Raphael or Raph is one of the main protagonists of the 2012 TV series. He is the adoptive son of Master Splinter (Hamato Yoshi) and the adoptive brother of Karai (Hamato Miwa), as well as the biological brother of Leonardo, Donatello, and Michelangelo. He owned a pet tortoise named Spike, until Spike mutated into Slash. He then adopted a new pet whom he named Chompy Picasso. Just like his other incarnations, Raphael's wears a red mask and weapon of choice is his twin sai. His most defining character trait is his bad temper and bouts of rage, which he usually takes it out on Mikey. He's also been known to fight with Leo and Donnie, due to their occasional feud (Raph's sibling rivalry, jealousy that Leo is the team leader while Donnie is the team' scientist, mechanism and inventor). Raphael sports a chip in the bottom of his shell that resulted from an accident as a child during an fight between Splinter and The Kraang. He is voiced by Sean Astin in this series.
