Luke Triton is the son of Clark and Brenda Triton, and the apprentice to Professor Hershel Layton. He is studying to be an expert puzzle-solver and gentleman. He is also learning to play the violin. His talent, which is quite an unusual one, is that he can talk to animals.
He is scheduled to appear as a playable character in "The No No Name". In this game, he is 15 years old. (As opposed to being 10-12 in the games and the movie.)
