Starfy

Stafy (also spelled Stafi, Starfi, or Starfy) is the name of the hero of the Densetsu no Stafy (Legend of Stafy) series, so far only released in Japan. The Legend of Stafy series itself was created by TOSE, a second-party video game developing company of Nintendo.

Stafy is connected to the Mario series in many different ways, mostly through cameos.

Mario & Luigi: Superstar Saga
In Mario & Luigi: Superstar Saga, Stafy made a cameo appearance on a movie poster in the Yoshi Theatre.

Super Princess Peach
In Super Princess Peach, Stafy makes a cameo as the enemy known as "Starfish". The game's Glossary even describes him as "A star-shaped foe rumored to be the prince of a kingdom?"

Super Smash Bros. Brawl
Stafy also appears in Super Smash Bros. Brawl, as an Assist Trophy character. However, unlike most Assist Trophies, Stafy is vulnerable to opposing attacks, and can be sent flying out of the stage easily. He makes up for this with strong attacks, as well as a wide range of moves, such as a spin attack, and a fiery explosion.
