Kingdom Hearts: Next Generations is the second anime series of the Kingdom Hearts anime. It is the sequel to the anime, Kingdom Hearts (2008 TV series), and is followed by Kingdom Hearts: Guardians of Light. It was focused on Sora and his friends' continued battle against the Darkness. The storyline is notable for having matured the characters and taking a darker tone, with increased narrative complexity and frequency of character deaths. All main, recurring, and supporting characters have vastly different appearances compared to the first season, as a new anime team and style was brought in order to give the show a sleeker look.
Sora, Donald and Goofy have been asleep for 3 years, regaining their memories. When Sora awakens, he eventually arrives in Twilight Town, the place where a mysterious boy, Roxas, lived before he suddenly left. Gaining new clothes and powers, Sora continues his quest by unlocking paths to new worlds, learning of Nobodies and fighting the Heartless, as well as facing the remaining members of the mysterious Organization XIII. Meanwhile, the mysterious disappearance of Tony Stark makes a 17-year old Theodore Detweiler put the Omnitrix back on, as well as forcing him to search and locate Tony. At the same time, he must enlist the help of the S.H.I.E.L.D. kids (children or grandchildren of retired S.H.I.E.L.D. which are commonly half human and half mutant), retired members of the Fusion Tenders and repel attacks from a new enemy, the Highbreed.
