Sonic X
"Sonic X", an anime series produced by TMS Entertainment and overseen by Naka, ran for three seasons (78 episodes) from 2003 to 2006. While previous series' episodes feature self-contained plots, "Sonic X" tells a single serialized story. The "Sonic" cast teleports from their home planet to Earth during a scuffle with Eggman, where they meet a human boy, Chris Thorndyke. Throughout the course of the series, Sonic and his friends attempt to return to their world while fighting Eggman. The second season adapts the "Sonic Adventure" games and "Sonic Battle", while the third season sees the friends return with Chris to their world, where they enter outer space and fight an army of aliens. Some critics enjoyed "Sonic X", while others disliked it. Although it suffered from poor ratings in Japan, "Sonic X" consistently topped ratings for its timeslot in the US and France.
