Raphael

Just like his unusual choice of weapon (the sai), Raphael is arguably the most complex dude out of the TMNT bunch. Raph's got a bit of a temper, you see, and a rather bleak outlook of the world. He has a difficult relationship with Leonardo, his older brother and the leader of the group.

Unfortunately, although maybe necessarily, in original, kid-friendly cartoon series, this complex character was simplified and was mostly known for his one-liners:

• "He's not only from medieval Japan, but also from an alternate universe, so naturally he speaks English!"
• "If he starts singing, I advise changing to another channel."
• "Thanks, Raphael, I owe you one!" "You owe me 6, but who's countin'?"
• "MMMph hmm MPHMMHM!" "That's April, alright. I recognize her mumbles!"
