- Not to be confused with Super Mario or Mega Mario.
Big Mario is the form Mario takes after obtaining a Big Mushroom in Super Mario Maker. Upon scanning 30th Anniversary Mario amiibo onto the Wii U GamePad's 
, a Big Mushroom will appear. It works only in Super Mario Bros. game style. With this form, Mario can break Brick Blocks and hard blocks by running into them at speed, as well as jumping onto them from above. Most enemies will be defeated instantly by stomping them. However, Mario is still vulnerable to enemy attacks. Depending on the scanned amiibo, Mario's appearance will be based on Super Mario Bros. and modern Mario.
Upon becoming Big Mario, several visual effects will change. Enemies will become Mario-themed, some wearing mustaches or Mario's cap, up to changing the appearance of other enemies altogether, such as Bullet Bills turning into miniature Luigis. The screen will also gain a filter that mimics the effect of a CRT television. These visual changes are purely aesthetic and do not alter gameplay, aside from Big Mario himself.
