As a whole, the franchise has sold 21 million copies and it reviews relatively strongly. Kingdom Hearts has even crossed over into Disney Infinity with the Kingdom Key being a special unlock for the more recent games. Due to Sora's increasing popularity, dedicated fans consider him to be the #1 choice to be a playable character in the Super Smash Bros. series. In 2021, Sora would make it into Super Smash Bros. Ultimate as the final DLC character of the roster. His English voice actor, Haley Joel Osment, reprised the character and he marks the only "celebrity voice actor" to appear in Smash. Sora is also the only Square Enix character to speak in English.
