With two decade's worth of games to pick from, these are some of the gigantic bosses and wily rivals Sonic and Sonic will be taking on in next month's Sonic Generations.

I always forget about Chaos. When I think Sonic villains, it's always Eggman in a mechanical hover-ball joined with some sort of giant robot suit. I guess that's a sure indicator of which generation of Sonic hit me the hardest. The only modern Sonic moment that's really stuck with me is that freaking whale from the first level of Sonic Adventure. Sega should create a level dedicated to punching that whale right in the face.
