|Power(s) given||Similar to Super Mario, but lets Mario break blocks by running into or jumping on them, and defeat most enemies in one jump.|
|First appearance||Super Mario Maker (2015)|
|Latest appearance||Super Mario Maker 2 (2019)|
Big Mario is the form Mario takes after obtaining a Big Mushroom, appearing in Super Mario Maker and Super Mario Maker 2. Upon scanning 30th Anniversary Mario amiibo onto the Wii U GamePad's , a Big Mushroom will appear. Mario can only get the form if the level is in the Super Mario Bros. style. With this form, Mario can break Brick Blocks and hard blocks by running into them with some 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, and he shrinks if he gets hit. Depending on the scanned amiibo, Mario's appearance will be based on his original Super Mario Bros. sprite for the Classic Colors amiibo or his original sprite with modern colors for the Modern Colors amiibo. If Big Mario grabs a Big Mushroom of a different color, the Big Mushroom's color overrides Big Mario's (for example, collecting a Big Mushroom in classic colors as a modern colored Big Mario makes Big Mario gain classic colors). Placing a Big Mushroom in any other style will still place the mushroom, but grabbing it will do nothing but give 1000 points.
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.
In Super Mario Maker 2, Luigi, Toad, and Toadette can also use this form. Besides the use of the characters' modern appearances (as only the modern Big Mushroom reappears), none of the aesthetic effects from the previous game return. Big Mario now reverts to Super Mario if hit, rather than Small Mario. Unlike in the previous game, Big Mario cannot break blocks from the side, only above or below him.
