Superstar Mario

Superstar Mario  (also known as Powerful Mario, Super Baby,  Super Mario, Super Baby Mario, Super Mario Baby, or Caped Mario ) is the form Baby Mario obtains when he comes in contact with a Super Star in Super Mario World 2: Yoshi's Island (and its reissue), Yoshi Touch & Go, and Yoshi's Island DS. Baby Mario gets a Super Cape, and the Yoshi turns into a Giant Egg. After the time runs out, the Yoshi emerges with Baby Mario. Superstar Mario gains speed, enough to dash on walls and ceilings. He can use his cape to float down slowly. Superstar Mario is also invincible against enemies, attacks, and even hazards such as spikes and lava but not bottomless pits. During development, the star item was initially conceptualized to turn Baby Mario into the mustachioed adult Mario, but it was pointed out this concept would seem strange. Shigeru Miyamoto joked he still prefers this early idea to the final version. Sprites related to this concept can be found in development assets.

Powerful Mario appears as Baby Mario's power-up in Super Mario-kun's fourteenth volume, the adaption of Super Mario World 2: Yoshi's Island. It enables Baby Mario to climb up walls and float as it did in the games, but it also gives him super strength. The strength enables him to beat up enemies and even use boulders to hurt Mario, Luigi, and Yoshi when he gets angry.

Superstar Mario appears as a Legend class spirit with a neutral type in Super Smash Bros. Ultimate. He is obtained when players level up the Baby Mario spirit to Level 99. His special ability is a First-Strike Immunity, in which the player who uses him gets a brief moment of invincibility if they get the first strike. He also comes with three open slots for support spirits.

The music heard in the background received rearrangements in Super Mario 64, Super Mario 64 DS, New Super Mario Bros., Super Mario Galaxy, and Super Mario Galaxy 2.
