Anime/Manga- No order, except Soul Eater is number one. I'm counting Avatar TLA as one. It's a tie with Soul Eater. If you don't want to count it, then just add DBZ to mine.
1. Soul Eater
2. Avatar: The Last Airbender
3. Yugioh GX/Orignal
4. Death Note
5. Pokemon (Early Seasons)
Honorable: DBZ and Naruto
