Transformed into a mutant from regular turtle form, Raphael and his three brothers learned a specialized form of martial arts and fight to destroy Shredder's evil ways. Many means of teaching by their sensei Splinter, Raphael and his brother a mean, green, crime fighting team. Raphael is the hot-headed, aggressive, wise-cracking turtle. The dual sai are almost a clash to Leonardo's dual katana's and how fitting that is. For Raphael was always arguing and fighting with his brother. He always had some way to rebel against him, for they just didn't see eye to eye. In contrary to fighting with Leonardo, Raphael got along real well Michaelangelo and Donatello. In battle some say raphael is the deadliest to fight because he fights with anger and agressiveness that isn't seen in the other 3. Even with his short temper, Rapahel is a favorite, for he definately is one of mine.
