This year for

Dr. Horrible
Looney Tunes / Merrie Melodies
Freakazoid!
The Spectacular Spider-Man (animated)
I also tried to nominate The Middleman and My Own Worst Enemy, but someone else seems to have already done it. I also goofed and added too many character names (but the mod forgave me. *bows*) for Freakazoid! But who wouldn't want Foamy the Freakadog on their list of characters? It would be a crime to exclude him. ;D
