Sora

Sora is the protagonist of the crossover video game series Kingdom Hearts by Disney and Square Enix. The series pits him fighting alongside and against various Disney and  characters, including Cloud Strife and Sephiroth. Sora wields a Keyblade as his weapon of choice. Sora holds the distinction of being the last DLC character added to Super Smash Bros. Ultimate.

Super Smash Bros. Ultimate
On October 5, 2021, Sora was announced to be the last DLC character for Super Smash Bros. Ultimate and was released alongside his home stage Hollow Bastion as part of Challenger Pack 11 on October 18, 2021. According to Sakurai in Sora's reveal trailer, Sora was the real winner of the Smash Bros. Fighter Ballot held in 2015 for Super Smash Bros. for Wii U and Super Smash Bros. for Nintendo 3DS; though the contest concluded with Bayonetta being added to the game, Sakurai stated that this was because Sora was not considered a realistic option at the time. Sakurai has stated that Sora was originally not going to be part of the game and that there were only supposed to be five fighters in Fighters Pass 2. He stated that he met a Disney representative that was open to the idea, and after some discussions, they decided to add him as an extra character.

Sora is a lightweight character who possesses a unique midair jump, ascending a further distance in a curved trajectory in a similar manner to Ness or Mewtwo. If Sora wins a stamina battle, the screen will zoom in and slowly fade to white, a reference to the victory animation that occurs when defeating a boss in the Kingdom Hearts series.

All of Sora's alternate costumes are based on each of his outfits in the series. While the default one is from the first Kingdom Hearts, the second one is from Kingdom Hearts II, third from Kingdom Hearts 3D: Dream Drop Distance and fourth from Kingdom Hearts III. The rest are various forms of him from the games; the fifth, sixth and seventh are the Timeless River form, the Valor Form and Wisdom Form from Kingdom Hearts II respectively, and the eighth and last is the Ultimate Form from Kingdom Hearts III.

Classic Mode route
All matches in Sora's Classic Mode route are Stamina battles, except for the final round.

Palutena's Guidance
Sora shares this stock conversation with all other DLC characters except Piranha Plant. It was originally used for Mewtwo, Lucas, Roy, Ryu, Cloud, Corrin, and Bayonetta in Super Smash Bros. for Wii U, who are downloadable fighters in that game.
 * Pit: Who is THAT?
 * Palutena: I have no data on this fighter. I can't believe it!
 * Viridi: It must be an intruder from another dimension!
 * Pit: Whoever it is, the goal remains the same: to fight and win!

Trivia

 * The announcement for Sora in Super Smash Bros. Ultimate was paired with an announcement that the three mainline Kingdom Hearts titles (' + ', ' and ') would be coming to the Nintendo Switch via cloud streaming.
