The Artifacts are gadgets made by Alphys for either defense or transportation purposes.
So far its unknown how these are created, but they are useful for an emergency.
The Artifacts are a round mechanical sphere with a similar appearance to the one in "The Artifact Room" but only smaller with different shapes on the left side of the device and a different pattern to it. These items have two different types with different colors which currently known are green and a light blue. As we seen so far there are two types of Artifacts in the series.
The Green Artifact that has three small circles on the left side of the sphere. Both the top, and bottom have a metal plate while there a white line (paint or wires) making an L shape.
The Light Blue Artifact with some small triangles on the left side of the sphere. Both the top, and bottom have a metal plate while there a white line (paint or wires) making an L shape.
- Green Artifact: This artifact can create a green shield just like what a soul of Kindness can do for defense or to trap a person inside. A perfect example was when Alphys trapped Akumu inside of the shield.
- Light Blue Artifact: This artifact has the ability to teleport people to a different location but it can only do a certain number of people at a time.
