Character design would be like this: A minifigure with an exclusive hat. Or like this: A new head. Personally, I like the hat the most. Comment on which one YOU like best!
Sonic X Subseries
A subseries about Sonic X would be made February 2012.
A video game called Lego Sonic: The Video Game would be released later on. Another video game called Lego Sonic X: The Video Game would also be released, but split into two games, Lego Sonic X: Seasons 1 And 2, and Lego Sonic X: Season 3.
