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 was also the pet owner of Spike, until he mutated into Slash. Just like his other incarnations, Raphael's weapon of choice is his sai. He wears a red mask and fights with two sai. Known for his rage, he commonly takes it out on Mikey, and on occasions, to Leo and Donnie, due to their occasional feud (Raph's sibling rivalry, jealousy and power hunger 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 as a result of Splinter's earlier encounters with The Kraang that were after him. He is voiced by Sean Astin in this series
