Which of these characters would most likely to work with if you want to rule the world?
L (One of the most smartest characters of all of animes, hes just awsome, he could work with almost anyone, and he could actually rule the world due to his unique solving methods)
Itachi Uchiha (Mangenkyo Sharingan, he's my favorite Naruto character, who doesn't?, I guess he could work with anybody. I don't this the great Itachi is THAT powerful to rule the world, but his mind is a little similar to L's)
Light Yagami (He has the Death Note, and he was close enough to actually changing the world)
Lelouch Lamperouge (Geass, he's another smart one and another of my favorites. He did rule the world for a short period of time T_T)
Kenpachi Zarakai (Two words...Epic Ownage. He could just take off his eye patch and you feel like you got hit by a nuke. Teamwork is not an option though.
Cell (I'm not really a huge fan of DBZ, but, he could destroy the Earth in any day. Teamwork isn't that good too, he'll probably just kill you if you join him)
Other People I forgot to mention...
