|“||You can't hide from your fears forever.||„|
|~ Bete's hidden dialogue at the end of Dust|
Bête Noire, often referred to as Betty, is the main antagonist of Season 2. She is a physical incarnation of the soul trait FEAR, and was created to ensure humans and monsters will never live in peace. She seeks to gain the power to fulfill her purpose, and is a spell that lacks some human emotions.
She is voiced by Courtney (ProjectSNT).
Bete physically appears as a cute preteen girl that has brown hair with tips of pink on the edges that's about medium-long. The closer she is to be able to use her Rhabdophobia magic, the pinker her hair will be, starting from the bottom. Once Rhabdophobia is available for her, her hair becomes completely pink with no trace of brown. She wears a magenta skirt which had its edges torn as seen in the My Promise trailer (referencing Amber's torn skirt in Glitchtale Origins: The Black Beast), a light purple turtleneck with a large light pink stripe at its bottom, light purple leggings (except in My Sunshine) and brown boots that are pretty close to reaching her knees.
She has pink pupils that become brighter when HATE controls her and her white sclera turns darker depending on how much HATE is being used and her mouth becomes crooked and fully black if the HATE takes over.
With her soul intact, her sclera becomes a dark shade of magenta, her pupil becomes a darker shade of pink, and her mouth becomes more crooked, similar to Kumu's. Her body is no longer empty and is filled with pink magical matter.
|“||...she sacrificed her own soul to create the most powerful and destructive being imaginable. A creature whose sole purpose is to ensure that humans and monsters would never live in peace.||„|
Hundreds of years ago, there lived a innocent girl named Amber that had a Kindness and Integrity soul. She lived a happy life as the younger sibling of Agate Lightvale, (The Wizard of Bravery) and Copper Lightvale (The Wizard of Determination).
However, everything changed after Agate and Copper began to argue over the barrier. Copper, wanted to break the barrier and set monsters free from the Underground, while Agate, said it was better not to break the barrier and maintain the peace.
Both of them strongly believed that their idea is the right decision, Which eventually led to them battling, with Amber watching them. At the end of the battle, Agate lost, causing her to feel great humiliation, she lost her trait because of this and then fled.
While Agate was gone, she was searching for a trait that is able to defeat determination. Copper, on the other hand, was having a difficult time taking care of the kingdom on his own, and having to deal with a lot of responsibilities.
Then, when Agate returned to the kingdom, Copper and Amber gave her a warm welcomed due to her long dissapearance. After some time, she challenged her brother again, except against his will. This time, however, she was winning. During the fight, Amber tried to escape, but her sister blocked her from escaping by using her magic, and then murdered her. This caused Copper to lose his trait, resulting in his soul turn into a grey soul. She then killed him brutally with her spear.
|“||And with that, little Amber... my life is yours...||„|
|~ Agate Lightvale on "The Black Beast" speedpaint by Camila|
Agate won in the battle, she realized that her soul was cracking and she was dying slowly after she reverted her trait. Knowing that her time was running short, she sacrificed her soul to create a powerful creature that would destroy all of Monsterkind and mankind , Bete Noire , by using Amber's body as a vessel for her soul and as a physical form for the fear.
Bete Noire's Awakening Official Comic
Post-Love Part 1 Official Comic
|“||That was awesome!||„|
|~ Bete to Frisk, also an example of her "energetic" personality|
|“||Your soul is very special Asriel. Mind if I take it? Kumu is hungry.||„|
|~ Bete talking about Asriel's soul in Dust, also showing her sadism|
Quick to smile and bursting with energy, Bete seemed to be incapable of cruelty at first glance. She seemed naturally cheerful and was typically seen smiling. She wielded a somewhat happy-go-lucky attitude, and never seemed to worry about the future. In fact, she was never seen feeling hopeless. Also, she treated her peers with great friendliness and was quick to greet Jessica and Frisk when she met them.
Despite appearing sweet and innocent, Bete's personality easily changed after Dr. Gaster read the tale of two siblings, and Asriel and Sans discovered some AMD footage of her doing questionable things. Here, Gaster learned that the Agate Lightvale sacrificed her own soul to create a powerful creature that would make sure monsterkind and humanity never live in peace. Afterward, she wasted no time trying to hide the monster inside of her. Bete revealed that she enjoys it when she severely hurts others (both physically and emotionally), indicating that she has a very sadistic, and violent personality. She appears to enjoy hurting her opponents before she kills them. In fact, Bete is known for attempting to kill anyone in her way. It's also clear that she has no problem lying to, or betraying others. Bete is very manipulative, as they manipulated Jessica, Undyne, and Asriel into doing what she wants them to do. An example is when they casted a hallucination on Undyne, causing her to kill Alphys instead of killing Bete.
When it comes to battles, she often becomes arrogant, which results in her underestimating her enemies. She's not a very good strategist, and relies on brute force. A bit of planning can outsmart her very easily as seen in her fight with Gaster.
Bete might suffer from necrophobia. If a foe tries to attack her with a powerful blow, she wears an absolutely terrified expression on her face. It is also known she fears death. She is also calculating and knows how to get what she wants.
Like a majority of Glitchtale villains, Bete, for the most part, thinks that what she is doing is right. According to a post, and a couple of lines from Scared of Me, she believes that monsters and humans living together is "like a time bomb waiting to go off". Therefore, she thinks that what she's doing "just speeding up the process". In fact, Bete's views on humans and monsters living together is the exact same as Agate's. In addition, she knows everyone's past, as she can read anyone and how their past was like. She uses the mistakes of other character's to justify what she does. An example is when Asriel (As Flowey) killed almost everyone in the Underground, she considers this act distasteful.
However, it's clearly not her fault that she's evil. This is shown in the comic that showed her awakening. Here, she seemed to be a good person until she remembered Agate Lightvale commanding her to do her evil deeds. In a post, it was revealed that she is unsure if what she was doing was right or not. She even seems to care about Akumu. For example, in Do or Die, she seemed concerned when the creature was hurt in their battle with Dr. Gaster. Both Kumu and Bete treasure each other as their best and only friend. But Cami said it was kind of like instinct since they need each other to live. If one of them dies, the other dies slowly due to lack of magic.
While under HATE's control, Bete acts far more violent and insane. In this state, if she gets into a battle, she mercilessly attacks her foes with a twisted black smile on her face. Also, Bete seems to be scared of the HATE's plans. This means she knows the hate has different plans than her own. Most likely because Bete only has the intent to kill Frisk and killing others aren't really necessary unless they need it for power. While HATE just wants to cause chaos and havoc with no purpose to do so.
- Akumu: Before the two fused, Bete was capable of using Akumu as a weapon, as seen in Do or Die. The creature can form various weapons, such as a scythe or an arm-mounted blade. Bete can also send Akumu to attack alongside herself, as seen when she used it to destroy one of Gaster's hands.
- Summoning/Life Creation: In Do or Die, Bete summoned a plethora of Pink Creatures to serve her. These lifeforms can transpierce others which removes their soul, and they can also disguise themselves as others.
- Hallucination Casting: Due to having the Soul of FEAR, Bete can cause others to hallucinate and she can control these hallucinations. She often uses this power to strike FEAR into an opponent's heart by creating hallucinations of someone, usually a loved one. Then, she jars them with a frightening change. For example, when Bete stole the vial that contained the HATE substance from Jessica Grey. Bete made her hallucinate that she was her daughter, then she jarred up the hallucination by giving her a demonic pair of eyes and a sadistic smile with her clothes torn up. She also displays this ability when she encountered Asriel and Sans. In which, she used her illusions to fool Asriel in believing that she was Chara, causing him to freeze in his tracks so that she could strike Asriel with her powerful spear.
- Immortality: Bete is shown to be biologically immortal and possesses eternal life, or at least an extended lifespan, having been around for around 300 years. In addition, she is resilient against physical damage; even before she attained her healing factor, Bete was unaffected after Undyne stabbed her in the shoulder.
- Mind Reading: It is confirmed in the above conversation between Bete and Akumu that she can read memories and look into one's soul by looking at the victim's eyes. This is presumably also how she figures out her victims' worst fears.
- Rhabdophobia: Bete's special attack that creates a negative pink area where she takes control of all enemy magic and allows her to use it against her enemies. Bete doesn't waste her powers by controlling an enemy's magic since it forces the target to use its own magic against themselves. Rhabdophobia has a couple of meanings, but in this context, it means "FEAR of Magic."
- Statistics Amplification: Bete usually grows stronger when more fear is around, the closer she is to death and how many souls she has. She feeds on the fears of others and even their own to get stronger. Usually when closer to death she grows stronger depending on how close she is to dying. This is seen in Do or Die; when Gaster was about to blast a beam from his Gaster Blaster to Bete, her hair turned fully pink and with enough strength, Akumu escaped the green force field Gaster trapped him in.
- Mind Control: Through HATE, Bete can corrupt souls and force them under her control. Sans was the first victim of this power and Asriel followed not long after. It seems that the victims' souls must be in Bete's ownership before they can be affected.
- Forcefield Creation: In Love, Part 2, Bete conjured a humungous dome of darkness/HATE around the part of the canyon where she was fighting Frisk.
- Regenerative Healing Factor: Thanks to HATE, Bete possesses a regenerative healing factor, allowing her to heal wounds almost instantly and regrow limbs. However, it can be overtaxed and it is confirmed that the regen can't heal everything.
- Energy Manipulation: At multiple points in Glitchtale, Bete has been seen utilizing what seems to be an energy of sorts, starting with light energy conjured from her spear in Do or Die, used against Gaster. In Love, Part 1, Bete conjured dark energy and swung that at Undyne. In Love, Part 2, Bete summoned a wave of pink energy by slamming the ground, and in My Promise, pink energy emanated from her body.
- HATE Tentacles: In Love, Part 2, Bete extended a HATE tentacle from her right shoulder after Frisk severed her arm.
In addition, Bete is shown to be quite strong physically — able to heavily damage a wall with a single, casual punch in My Promise — and very agile and athletic. So if your over weight, you might not escape her.
|“||Hey! Thanks for saving me from that! Aren't you... Frisk? (Frisk: Yea!) My name's Betty. I saw you all over the news a month ago, pleased to meet you.||„|
|~ Bete introducing herself to Frisk|
As Frisk was making their way to the Anti-Monsters Department (or AMD) HQ, they spotted Bete carelessly roaming the streets. It seemed like she was about to get hit by a car if it wasn't for Frisk, who summoned their shield to protect her.
At first, the two seemed to get along, and Frisk continued their journey to the AMD HQ. Here, Frisk hoped to convince the AMD leader, Jessica Grey, to sign a peace treaty between monsters and humans.
After Frisk successfully managed to convince Jessica to give them a chance at showing her that monsters are kind creatures, they took her and Bete to Gaster's lab. Here, she met Gaster. He explained to Jessica how the core's expansion would be helpful to both humans and monsters. Bete was presumably listening because, according to a Tumblr post, Bete was looking for something in Gaster's core.
Next, Frisk took Jessica and Bete to Toriel's school, where they asked Toriel to make one of her students demonstrate how to use their magic. During the demonstration, however, a pink blob-like creature popped out of Bete. Bete told everyone that the creature was Akumu (or Kumu for short), her "overprotective" helper.
Frisk later took Bete to Grillby's, where she met Sans and Asriel. Here, they questioned Bete about her soul and her magic. This forced her to tell them that her soul was no ordinary soul; it was pink. Upon learning about her unique soul trait, Gaster started researching about "Bete's Soul".
Eventually, the conference horribly erupted into chaos from the revelation that Asgore had murdered Alina, Jessica's daughter. Afterward, a shadow-like creature (presumably Bete herself) gave Jessica an offer; if she did exactly what she told her to do, she would help her deliver out her revenge on Monsterkind.
|“||The pink trait... the 'Bete Noire'... (Grins evilly) The soul of FEAR.||„|
|~ Bete revealing her soul trait and her true self|
After the episode's introduction, Bete appeared when Frisk visited Gaster. They asked him if he found anything about her soul. Sadly, at the time, he had found nothing. Before they left to see Mettaton's first live performance, Bete decided to come along with them along with Papyrus, Sans, and Asriel.
When they arrived, Bete decided to go talk to Mettaton. Meanwhile, Papyrus spotted a girl stuck on a crane that was holding slabs of concrete. However, Bete was presumably controlling the girl, whic was just an illusion she created and was using her powers to conceal the fact that wasn't a real girl from Papyrus's view.
After he succeeded at moving the crane above the building's ceiling, the illusion that looked similar to Agate commanded him to push a button, resulting in him unintentionally dropping the concrete. Luckily, Sans used his powers to stop the concrete in its place. Using this opportunity, Jessica Grey, who was waiting for this, shot him with the Anti-Magic Ray.
Later, Sans and Asriel teleported to the AMD's recording room, where they investigated the camera's recordings; Asriel believed that the AMD was involved with what happened. The two of them then saw the recording where Frisk saved Bete from the car in the previous episode.
Instead of a car appearing, nothing was there, indicating that she was using her powers make Frisk see a car. The two also saw a recording of her leaving Gaster's lab during the conference. With this, Sans and Asriel learned that she was secretly orchestrating the events that occurred from the attempts to make peace with humans and monsters.
Before the two could leave, Bete entered the room. She wasted no time revealing her true nature. She told them that she really wanted to keep it a secret longer and spoil it herself, but that didn't really matter to her as she has all the information she has anyway. Then she talks about Asriel's soul and talks about how special it is. She hallucinates Asriel into seeing Chara, causing him to freeze in his tracks. Little did he know that she was going to stab him with her powerful spear. She threw her spear, but Sans, having failed to stop the attack with telekinesis due to being hit by the Anti-Magic Ray for the second time, teleported in front of him, sacrificing himself. She then took his soul and fed it to Akumu, turning him into dust. Asriel attacked her in grief, only for Akumu to shield her from the projectile attack. He prepared another attack, before retreating after remembering Sans telling him to warn the others.
Bete proceeded to order Jessica Grey to give her the HATE vial. When she refused, Akumu brutally grabbed her by her neck and pushed her against the wall. Bete then conjured an illusion, masquerading herself as Alina. She then jarred up the hallucination by giving her demonic eyes, cuts and scrapes, and torn up clothes. The episode then cut to black, with Jessica's screams audible in the background.
|“||Don't worry, I'll keep my promise! I'll turn all those monsters to Dust.||„|
|~ Bete talking to Jessica at the end of Dust|
Canon Conversation with Akumu
This conversation took place after the Dust episode, as we understand from the dialogues.
- Bete Noire: What am I?…
- Bete Noire: Something made to be hated?…
- Bete Noire: … Looks like it…
- Bete Noire: I never asked to be made…
- Bete Noire: I didn’t ask to be this way…
- Bete Noire: But it’s what I am. And here we are trying to fulfill our purpose despite our doubts…
- Akumu: …
- Bete Noire: I know we don’t have other choice, you don’t need to remind me that.
- Bete Noire: Plus, we’ve already started. There’s no going back now. * We gotta make mom proud…
- Akumu: …
- Bete Noire: She told me you are and will be my only friend. That we can’t trust humans… that monsters are dangerous…
- Bete Noire: That a civilization where the 2 races live together, is just a time bomb waiting to go off.
- Bete Noire: That we’re doing good by speeding up the process.
- Bete Noire: She’s right… I’ve seen what they’ve done. As soon as I look at someone’s eyes, I can see straight to their souls, like a window. It shows me everything, good and bad memories.
- Bete Noire: Frisk looked nice and innocent at first. But then I saw the horrible things they did to his so called “friends”…
- Bete Noire: Then I thought monsters would be different… I saw Asgore… Those poor children.
- Bete Noire: Then I saw Asriel, I thought his son would be different. But he was also keeping his secrets… he looked cute as a flower tho.
- Bete Noire: The small skeleton was no different. He watched it all happen at first. And only intervened at the end. Only to murder them until he lost count.
- Bete Noire: Trying to pretend something they’re not. Ha! And they got angry with me for doing the same. Hypocrites.
- Bete Noire: I can see why mom wanted me to do this. I’ll do everything I can to fulfill my purpose.
- Bete Noire: Humans are easier to deal with, most of them don’t even have magic, get their souls will be easy. Monsters… will be slightly harder, I can’t trick Jessica again. But at least, I think I got rid of the strongest one.
- Akumu: …
- Bete Noire: What’s wrong kumu? Was that soul not enough?
- Bete Noire: what?… it’s not drained yet? And you had enough to put the plan in action… would you look at that… and it still has a good portion left. We won the big prize with this one. It’ll be a while until it shatters.
- Bete Noire: … don’t look at me like that, you’re always hungry.
- Bete Noire: … hm? Sleep? What’s “sleep”? Oh… that human/monster thing… what about it? I don’t want to sleep… I… don’t know how to…
- Bete Noire: So we’ll just wait for the sun to come out and we’ll do our thing ok? Just, get ready… it’ll be a long day…
|“||Kill them, Kumu.||„|
|~ Bete ordering Kumu to kill Alphys and Jessica Grey|
Around the beginning of the episode, Bete was shown waiting in the core with Akumu. Soon, Akumu grabbed her attention and showed her Sans's soul, which was having its magic drained. She realized that the magic Akumu absorbed from Sans's was enough to start her plan and the screen then cut to black.
Later, it was revealed that Bete needed to drain a monster's/human's magic so they could create an army of Pink Creatures that she would use to search and steal the souls of humans. She is briefly seen commanding a Pink Creature(s) to kill Alphys. While the Pink Creature(s) were beginning their "soul harvest", Gaster, who was accompanied by Alphys and Jessica Grey, cornered Bete in the nullifier room, forcing her to fight Gaster. He hoped to kill her himself and, if he failed, Alphys would activate the nullifier room, which she hoped would kill her once and for all.
As the "soul harvest" continued, Gaster and Bete continued fighting. During their fight, the slimes managed to gather some souls from human children. Gaster didn't know at the time, but, Bete's special attack, Rhabdophobia, was almost charged up.
During the fight, Gaster delivered serious damage to her. But, before he could finish her, a slime attempted to kill a girl named Lily but, her brother Cam sacrificed himself. But, as a result, the slime took his soul and Bete managed to fully charge up Rhabdophobia.
This allowed her to take control of his hands and his Gaster Blaster. She brutally attacked him and attempted to kill him by stabbing him in the back with her spear.
Luckily for him, Jessica and Alphys came in just in time. Jessica shot Bete, temporarily incapacitating her, after which Alphys gave Jessica an indigo artifact, allowing her to teleport back home with Gaster. Kumu attempted to attack her, only for Alphys to put up a shield around her. She planned to use the nullifier to kill Bete once and for all. She managed to activate it and it attacked her.
Alphys' shield soon disappeared, resulting in Bete impaling her with her spear. The nullifier didn't affect her; it only works on monsters and humans, but she was neither. Next, Undyne entered the room. She summoned her spear and launched it at Bete, only for Bete to hold Alphys' soul in the spear's path, resulting in Undyne accidentally killing her. She then took control of her spear and attempted to use it to kill Undyne too. However, she, due to her immense Determination, transformed into Undyne the Undying. The episode then ended on a cliffhanger.
|“||WHY DID YOU DEVOUR THE ENTIRE THING YOU IDIOT!? (Coughs up HATE) I-I'm sorry for yelling... Akumu, this...this darkness...this horrible substance...we underestimated so much... I hardly feel like myself now. I can feel our goals, our very reason for existing slipping from our grasp. Kumu... I feel that this HATE has its own plans... I don't know how long I'll be able to decline them...||„|
|~ Bete chatting with Kumu on how she felt after the creature ate the HATE vial|
This episode begins with Bete confronting Undyne the Undying. Thanks to her determination, Undyne easily overwhelmed her. Eventually, Bete's patience ran thin. She charged up Rhabdophobia and attempted to use it on Undyne's spears.
Unfortunately for her, Undyne just created more spears, aimed at her, and finished her off with a giant, red energy spear that created a massive explosion. The blow from the spear was so powerful that it blew the roof off the Nullifier chamber and disintegrated Bete's back.
Kumu, still alive, consumed the HATE vial, transferring its effects to Bete. Revived and intact, but visibly under the effects of HATE, Bete attacked Undyne again. Later in the fight, she began to cough up the HATE substance. This forced Bete and Kumu to retreat through the broken roof.
Later, Bete and Akumu were seen hiding in a rundown shed. She revealed to Akumu that she didn't feel like herself after consuming the HATE, and the fact that she was terrified of the HATE's goals. This means that she has standards.
Kumu comforted her as the Pink Creature(s) she created to gather human souls from the school arrived. She explained to Kumu that she had done what she needed to do; make Frisk look for them. The creature then consumed a large number of souls collected by the Pink Creature(s) before the scene cut to black.
Bete and Kumu were later mentioned by Frisk.
|“||What took you so long? Did you need that much time to dry your tears? (...) Now that's more like it.||„|
|~ Bete taunting Frisk before their fight|
Bete soon encounters Frisk and the two begin to fight. Thanks to Bete's ability to use HATE, she gained a massive advantage. During the fight, she managed to use Frisk's bad memories from their genocide route to deplete their DETERMINATION until it was almost gone. Later in the fight, Frisk was about to be killed if it wasn't for Asriel. Using her illusions, Akumu managed to kill Asriel and take his soul.
Frisk then managed to increase their LV to 19 and continued to fight Bete. She was nearly completely overwhelmed by their incredible power, which is slightly enhanced by HATE. So she "called for help." She pulled out Sans' soul from Akumu and filled it with HATE. HATE's regeneration ability brought back Sans' body. Sans then could only obey Bete's evil commands.
Frisk clearly didn't stand a chance against Sans and was about to die if it wasn't for Papyrus's help. Bete began to notice Toriel, Asgore, Gaster, and everyone else approaching. In an attempt to not let them interfere, she created a giant HATE shield (like Chara did in Continue.) which shielded herself, Akumu, Frisk, Papyrus and Sans inside. Papyrus manages to take the HATE out of Sans using love. Then, the HATE shield shattered thanks to a beam emanated from Sans; as a result, Bete was forced to retreat with Kumu.
|“||I'm not scared of an angry boy anymore. I know all your tricks now...||„|
|~ Bete intimidating Frisk|
When the episode began, Bete was seen furious about the fact that people were supposed to fear her but she has repeatedly been forced to retreat. She then made Kumu show her the souls that were collected from the soul harvest. Unfortunately for her, all of the souls were infected by HATE, except for Cam's soul. While draining it, she told Kumu to destroy all the souls, with the exception of the rainbow one. After Cam's soul cracked, she told Kumu to use some HATE on Asriel's soul. After finishing the process of bringing out her new look, Bete told Asriel that they'll go hunt down his parents because they hurt him so much.
Later, when Frisk, Asgore, and Toriel came to the arena, Bete decided to "go say hi". Frisk, noticing Bete about to attack them, used a shield to try and block her attack, only to be sent backward from the impact. Asgore tried to attack her, but she effortlessly dodged the attack. She said that she was just going to fight Frisk, but Asgore and Toriel would get to fight somebody; Asriel Dreemurr.
Bete swooped in behind Frisk, who tried to attack her. However, she just blocked the attack. She claimed that she's no longer scared of them because she knows all their tricks.
After Asriel stabbed Asgore, and Frisk tackled him, Frisk told Asgore and Toriel that they'll have to retreat. Bete however, didn't want them to escape and made Asriel attack Frisk.Pink Creature(s) surround the area and tells them that they'll see who will be running away this time.
- Bete's "new look" in My Promise isn't actually a transformation, but her real appearance. In fact, what the audience has seen until My Promise was her transformation.
- When Bete damaged Gaster's soul in Do or Die, it triggered the first flashbacks he had on his experiences in the void.
- Before Love Part 2 was released, Camila said that Cam's soul is the most powerful soul Bete has collected.
- Bete doesn't have a gender..
- Betty's real name, Bete Noire, comes from the French term Bête Noire, which means "someone or something that one particularly dislikes." This is fitting, as, for her creator, Agate Lightvale, monsters were her bête noire. This could also be referring to the fans and most Glitchtale characters, as several people have a dislike towards her. Bete Noire in French specifically means "Black Beast".
- Camila said in the description of her speedpaint "The Black Beast" that one of the other reasons why Bete is also called "Black Beast" is because Bete feeds on HATE in order to get stronger.
- Betty is a nickname for "Bete Noire". 
- Bete's special attack was first announced in an amino post of Camila.
- Veir stated that "Bete fears death".
- "Do or Die" confirmed it when Bete was about to be killed by one of Gaster's gaster blasters.
- In My Sunshine, Bete can be seen looking around the AMD HQ while Frisk was talking with Jessica.
- Bete seems to grow more powerful by absorbing human and monster souls, which also causes her hair to turn increasingly pink. It also activates her special attack, Rhabdophobia.
- Camila Cuevas once had Bete's profile photo on YouTube, even before she was seen in the series.
- It was revealed in Do or Die and the description of a speedpaint video that one FEAR soul can exist at any moment, and the same goes for determination.
- Gaster told Frisk in Do or Die that only a fear soul can defeat a user of the determination soul trait and vice versa.
- Rhabdophobia (in the case of Bete's special attack, since Rhabdophobia has multiple meanings) is the fear of magic. This information was uncovered at the beginning of a speedpaint video.
- Bete does not eat, sleep or bleed. This was shown in Love, Part 1, when Bete did not shed any blood after being hit by Undyne's spear.
- If Akumu dies, Bete will slowly die, and the same applies to Akumu. The same is true for both, but they do not die immediately, it should take a while. If this were to happen, the cause of death would be from running out of magic, because they use magic to live
- Camila once said on her Tumblr page that the Bete's soul was pink because pink is a color that looks innocent and can also trick the characters and the audiences.
- In one Camila's tumblr post, Camila released a canon conversation between Bete and Akumu that was never shown in-series.
- Before Dust came out, Camila released a screenshot, which features Sans and Bete. .
- Bete is afraid of HATE's intentions.
- Killing monsters and humans are none of Bete's intentions, although it's enough to stop her. It's not necessary to kill them all.
- The traits FEAR and DETERMINATION counter each other.
- The Bete Noire Spell is a couple hundred years old, but Betty's body age is 13, and it will never progress.
- Camila doesn't want to explain why Bete is interested in Asriel's soul.
- According to a post, Bete was looking for something in the CORE. And, in another post, it was revealed that she was looking for a "very special" soul in Gaster's lab that might be hidden within the CORE. Looking closely at the power generator in the True Lab, a faint red heart could be seen, which might have belonged to a previous Determination soul bearer. After all, Determination can "refuse to die", which might explain why it was taken out of the host without being shattered. But, since it cannot return to whoever it host was, it seems as this SOUL lacks the Determination to return to the bearer.
- Much like Chara, if Hard Mode wasn't activated, Bete would never have existed in Season 2 and the consequences of her activities would have never occurred.
- Agate Lightvale is technically Bete's mother because she created her.
- Bete is not strong enough to beat Undyne.
- Bete doesn't care that the timeline will be erased if she kills Frisk.
- If you invert Bete's colors, you can find Amber.
- Bete is trying to be careful with HATE and she is trying to not use it. If she uses too much HATE, it will take over again. 
- Bete isn't the first Bete Noire spell to exist. There was someone else before her.
- Bete can never turn back into Amber because her soul is long gone due to Agate. After all, she has Agate's soul and NOT Amber's soul.
- Bete Noire knows who Amber is.
- The reason Bete didn't absorb Alphys' soul was because it wouldn't have made a big difference on her power.
- When Bete is consumed by HATE and her hair is fully pink, it doesn't mean she can use Rhabdophobia, it means she is terrified.
- If Agate used Copper as the vessel for the Bete Noire spell, the spell would've been stronger than Bete.
- Bete can be damaged by strong magic, but only truly defeated by Determination.
- Bete was originally supposed to be able to move between bodies, but Camila removed this idea.
- We have not seen Bete's 100%.
- Before My Sunshine's release (which was Bete's first appearance), she was announced in an amino post of Camila.
- A GIF of Bete and Kumu was published on Camila's amino before Do or Die was completed.
- Bete's special attack, Rhabdophobia, was originally supposed to be named Magicophobia.
- Bete feeds off magic in order to exist and if she runs out of magic, she'll die.
- Bete is mentally 29.
- Bete didn't wear leggings in the beginning of My Sunshine until the car scene.
- Bete let Frisk, Toriel, and Asgore escape because she was so caught up in wanting to be feared. 
- Bete doesn't have any human organs. The only way to kill her is to make her run out of magic or disintegrate her with a really powerful attack.
