Mr. Saturn

Mr. Saturns are alien-like creatures from the EarthBound/Mother series. In both games they reside in a location called "Saturn Valley", and speak their own language.

In the Super Smash Bros. series, beginning with Super Smash Bros. Melee, Mr. Saturns appear as weak tossable items. While they normally walk around on the stage, they can be picked up and thrown at another player for minor damage. However, they deal a great amount of shield damage; in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, a thrown Mr. Saturn can instantly break another player's shield. Peach (and Daisy in Super Smash Bros. Ultimate), when doing her Vegetable move, has a small (1/166) chance of pulling up a Mr. Saturn instead of a vegetable. In the Onett mission of Adventure Mode in Super Smash Bros. Melee, Mr. Saturns are the only items that appear.

In Super Smash Bros. Ultimate, a Mr. Saturn hat that Mii Fighters can wear, can be unlocked for 450 G.

In Super Mario Maker, a Mr. Saturn can be unlocked as a Mystery Mushroom costume, via the Event Course Welcome to Saturn Valley. Their appearance is based on the original Mr. Saturn sprites from EarthBound.
