I'm waiting for Megaman 10 also.
Zarake Kenpachi is from Bleach. you can find all the episodes online or probably rent some of the dvds to see if you like the series. I haven't watched an episode since like 190 or something. but kenpachi is one of the most bad ass characters among all animes. He's up there with Sephiroth, Rock Lee, Demon Eyes Kyo, Dante from Devil May Cry, Sylar, etc. etc.
As for Brokinarrow, I personally like the series, but I know a lot of people who don't. It's sort of the same concept as naruto. A bunch of normal kids have extraoridnary powers, although one of these kids is a death god (grim reaper). They help the fallen get to the spirit world. People that stay on earth turn to hollows (monsters who feed on other humans), in which the death gods needs to kill them with a special blade that will release their souls so they can escort them to to the spirit world Soul Society. In Soul Society there are 13 squads of shinigami (death gods). Zarake Kenpachi is the captain of the 11th squad which is known for being the most powerful and relentless. Kenpachi only really enjoys fighting. If his opponent is weak, he feels let down. When he fights strong opponents he starts having fun and doesn't hold back...
Mute this if you dislike Rob Zombie, but the video is pretty well made.
