From the shadows of the sewers to the heart of New York City’s greatest battles, Splinter stands as the wise and fearless mentor to the Teenage Mutant Ninja Turtles. Cloaked in calm wisdom (and fur), he’s trained his four turtle sons in the art of ninjutsu, turning them from pizza-loving hatchlings into shell-kicking heroes. With his sharp mind, sharper reflexes, and a lifetime of discipline, Splinter proves you don’t need a shell to be totally radical.
