Super Mario (simply called Mario in Super Mario 3D Land and Super Mario 3D World) is a form of Mario which he assumes by eating a Super Mushroom. Super Mario is twice as tall as his non-powered up form. He is able to withstand being hit by an enemy without immediately losing a life, instead shrinking back to Small Mario. He can also break Brick Blocks, and, as of New Super Mario Bros., earn multiple Coins from Coin Blocks in one held Ground Pound, unlike Small Mario.
Recent games depict Super Mario as Mario's default form. In fact, Mario always appears as Super Mario in the endings of Super Mario Bros. 2, Super Mario Bros. 3, Super Mario World, and New Super Mario Bros. Wii, and the opening movies created for Super Mario World: Super Mario Advance 2 and Super Mario Advance 4: Super Mario Bros. 3 depict Mario and Luigi's Super forms as their standard forms. The opening of New Super Mario Bros. Wii depict Mario, Luigi, Blue Toad, and Yellow Toad starting out in their Super forms, only to revert to the Small form in time for the actual gameplay. The same goes for New Super Mario Bros., but while off-screen, Super Mario/Luigi is actually heard taking damage, and, when coming back on screen, is Small. This means that Super Mario is now Mario's regular form, and he becomes small when damaged, not unlike Wario in Wario Land: Super Mario Land 3.
Appearances in Other Media
The term Super Mario was used to define what is otherwise known as Fire Mario on The Super Mario Bros. Super Show!. However, this was dropped for The Adventures of Super Mario Bros. 3, which used the correct term.
Unlike the games, the Club Nintendo comic "Super Mario: Verloren in der Zeit" depicts Super Mario as much taller than other humans, similar to Mega Mario. In volume 4 of Super Mario-Kun, Princess Peach attempts to aid Mario by throwing him a Super Mushroom. Bowser quickly steals it and eats it, becoming enlarged and going by the name "Super Bowser" (スーパークッパ). Mario tries to attack him, but Bowser easily deflects him, seemingly defeating him.
