Mr. Eraser is an ally in Super Mario Maker and its sequel, Super Mario Maker 2, who takes the shape of an eraser with legs and eyes. His icon is placed on the right hand side of the level creation screen, under Coursebot. Upon his icon being tapped, the player is able to remove spawned enemies and objects. He has three official courses made by him. Super Mario Maker 2 features Mr. Eraser in the game's story mode, appearing for the first time as a 3D model.
As seen in the game's E3 2014 trailer, there was originally an eraser that had a letter "E" on it, similar to the one in Mario Paint, which had the exact same effect. This old icon was later replaced with Mr. Eraser.
In Super Mario Maker 2, he has a more important role in Story Mode. In this game, he has courses, which are needed to help him to erase blocks that block a pipe's path. His catchphase is "Adios, amigo!", which means "Bye, friend!" in Spanish.
If the player tries to erase Mario using Mr. Eraser, it briefly tickles Mario and he laughs.
