Kumu... There you are...
~ Bete Noire

Akumu, or Kumu for short, is Bete's part. Not much is known about it/he.

The creature is voiced by Strelok, who also voices Frisk & Flowey and provides the sound design.

Personality Edit

You're always hungry.
~ Betty to Kumu, also showing Kumu's hunger for souls

Much like Betty, throughout My Sunshine and a portion of Dust, Kumu didn't seem to be evil. It acted somewhat friendly and playful, which was shown when it ran off with one of Gaster's books. However, according to Betty, it was a tad overprotective. But this all changed after the creature revealed the evil inside itself.

Kumu appears to be sadistic and doesn't care if it severely hurts others. According to a post, the creature wields a hunger for souls and treasures Betty as their best and only friend.

Not much else is know about Kumu's personality, apart from the fact that Betty is controlling the creature. This was revealed in the description of a speedpaint video.

Appearance Edit

He's so cut- oh...
~ Camila in a post.

Kumu is a bubblegum pink blob that has a face. It appears to be able to change its size and shape.

When in it's HATE form it gains black sclera and a black crooked mouth.

Abilities Edit

Shapeshifting - Akumu can change shape and turn into a wide variety of weapons and objects. An example of this is in Dust when Asriel tried to attack Betty.

History Edit

My Sunshine Edit

What is that thing? It's awesome.
~ Frisk complimenting Kumu
Don't come out! Stay there!
~ Betty to Kumu

After Frisk took Jessica Grey and Betty Toriel's school, when Betty was meeting Toriel, her soul reacted to Toriel's approach. As a result, Kumu popped out of Betty. The creature soon shapeshifted into a tiny flower on her head. Kumu stays on Betty's head as a tiny pink flower for the rest of the episode.

Dust Edit

When Frisk comes over to Gaster's house, Kumu can be seen playfully carrying around a book.

Near the end of the episode, after Asriel and Sans find out about Betty's true colors. Before leaving, Betty soon appears. She gave up on attempting to hide the monster inside her and removes Sans's soul from his body and fed it soul to Kumu.

Asriel soon escaped and Betty asked Jessica for the HATE vial that she had. After refusing to give it to her, Kumu grabbed Jessica and slammed her against the wall. The screen soon cut to black.

Do or Die Edit

Minutes into the animation, Kumu is seen with Betty at the Core. The creature soon shows Betty Sans' soul, which the creature was draining its magic. Betty soon realizes that she had enough magic to "start her plan" (which is the soul harvest.)

Before fighting Gaster, Betty is seen ordering Kumu to attack Alphys before one of her pink blobs attacked her. Later, Kumu fights alongside Betty against Gaster.

During the fight, Betty stabs Gaster in the back, causing him to pass out. But, Jessica and Alphys come in just in time. Alphys gave Jessica a dark blue artifact, allowing her to go home. Alphys put up a green shield around herself and activates the nullifier. The nullifier attacked Betty and Kumu.

Alphys' shield soon fell down. But Betty then attacked her. It turned out it didn't affect either of them; it only works on monsters and humans but she and Kumu were neither. Undyne soon entered the room. Betty then tricks her into killing Alphys and attempted to kill her too. But she turned into Undyne The Undying. The episode ended at this point.

Love Part 1 Edit

Near the beginning of the episode, Kumu and Betty fight Undyne the Undying, who easily overwhelmed the two with her Determination. Undyne then uses her special attack, "The Spear of Justice" that was able to disintegrate half of Betty's body and destroy the roof of the nulifier room. Akumu then ate the Hate vial they took from Jessica in Dust. Betty was able to recover half of their body using Hate. But this was still not enough to defeat Undyne. Betty then coughed out some Hate, not knowing what may happen to Betty both of them flee from battle.

Kumu consuming all the souls collected during the "soul harvest"

Later, Betty and Kumu are seen hiding out in an abandoned shed.  Kumu confronted Betty as Shen told the creature that she hardly felt like herself now due to the HATE. Eventually, Betty's pink blobs arrive. Kumu proceeds to consume them, and the souls they managed to gather.

Neither Betty nor Kumu was seen throughout the rest of the episode, not counting when Frisk mentioned them when we're talking to Asriel.

Love Part 2 Edit

IMG 6550

Betty and Kumu

When the episode began, Kumu was seen with Betty in an image inside Frisk's mind.

Later, the duo encountered Frisk and they began to fight. Before the duo could finish them, Asriel decided to interfere. However, Kumu managed to take his soul while he was fighting her. Upon seeing Asriel's "death", Frisk's LV became 19 and turned the tides of the battle as a result.

Kumu revealing Sans' soul

Getting an idea, Betty used Kumu to grab Sans' soul and fill it with HATE. Sans, now under HATE's control, began to fight Frisk. After Papyrus jumped in the fight and managed to remove the HATE from Sans, Betty and Kumu were forced to retreat.

My Promise Edit

Akumu was seen at the beginning of the episode, with Betty, who was furious that they were running away even though they were supposed to be feared. Betty orders Akumu to show them the souls that were infected by HATE, Akumu then shows Betty the souls they had consumed by making itself bigger and making a force field around Betty. Betty then starts cracking the souls due to the fact that HATE has infected most of the souls. Betty decides to keep Asriel's soul and absorb the magic of Cam's soul then tells Akumu to destroy the remaining souls.


Betty tells Akumu that she is tired of being split in two so she throws her spear at Akumu in order to fuse with them. The spear hits Betty and then slowly both Betty and Akumu start fusing transforming into their true form. Akumu was not seen again as they were fused with Betty for the rest of the episode.
