Pain

Pain is a major antagonist featured in the anime house series, and could be considered the leader of the villain house.

Personality
Pain is very serious and only talks when needed. He is extremely aggressive and will not hesitate to destroy anyone who gets in his way. Pain does have a sense of humor, as he had entertained Orochimaru when he had questioned why Vegeta went to Babidi instead of him.

Powers & Abilities
Pain wields the Rinnegan, and along with his other paths, wield the six paths of the Rinnegan. Pain isn't shown fighting much, but is shown holding his own and even overpowering Naruto in the opening.

Trivia

 * It can be assumed that since the other 5 paths were shown, that the Pain we see throughout the series is only a body which is probably controlled by Nagato Uzumaki.
