Quick note : the original game's design had Sonic bring a member of a band and having a human girlfriend named Madonna, among other weird ideas (including Sega of America insisting Sonic be from Nebraska. Yes, really!). The cartoons and comics quite likely drew ideas from these and other elements that didn't make it…

I've rewatched a good chunk of Sonic X with my kids. They've loved it. I find it inoffensive and think it holds up a LOT better than the 1990s shows.

Adventure Time is great, but seriously - no American Dad!, Animaniacs or Archer in the A category as runners up? All three are tremendous shows. (American Dad! is criminally underappreciated, and far better than the Family Guy success that enabled its existence.)
