Sans and Papyrus

Papyrus dreams of becoming a member of the Royal Guard of the Underground and hopes to catch a human to impress the head of the guard, Undyne. To do this, he and his brother Sans set up several puzzle traps in the Snowdin forest.

Some abilities:
the use of "shortcuts" that allow Sans to quickly cover large distances in a short time;
the ability to be in different places in the same room at the same time, which suggests that Sans has the ability to teleport;
awareness of timelines.
