Yu Yu Hakusho

From Asaction

Bleach's spiritual predecessor. Moved to Toonami after gaining huge ratings with the tween/teen crowd (where it was unfortunately watered-down for afternoon broadcast).

Also, there were about 10 million fighting tournaments in this one. (Actually there were only two, The Dark Tournament, and there was one during The Saga of the Three Kings, I dunno what it was, since I haven't seen the entire anime. The manga is like, way better)

Hiei (a demon with 3 eyes, the third one being an EVIL EYE!!! WOOOOO! SCARY STUFF!!!!!), like, PWNZ!!!!!

Also, episode 8 was like, da best ep EVAR!!!!1111!!
