Emergency Button is a recommended character (by yummysimon4) that appeared in Rescission. It was used by Firey to disintegrate Bubble at the start of the episode, then Pencil on Firey, Pencil on Leafy, and lastly Pencil on the other recommended characters in the episode, saying that she was "tired of [them] too". When activated, Emergency Button has the power to fire lasers that will disintegrate other objects upon contact.
