Lean more about Leonardo, the oldest brother of the Teenage Mutant Ninja Turtles!

Leo is your classic oldest sibling. He’s a little bit bossy, but he firmly believes he has everyone’s best interest at heart! As the oldest, Leo considers himself the leader of the brothers. He loves his family more than anything, and is willing to go to great lengths to protect them. Leo is deeply devoted to Splinter’s teachings, and encourages his brothers to follow all of Splinter’s rules to a T. Leo can be a bit more serious than the rest of his brothers, which sometimes (believe it or not) annoys Raph, Mikey and Donnie. But at the end of the day, he loves to joke around with the crew too - especially if they don’t break any rules in the process!

When Leo meets April O’Neil, things change in a big way. Before meeting April, Leo was content to live in the shadows and stick to the rules that Splinter laid out for him and his brothers, the most important being avoiding humans at all costs. But after meeting April, Leo is willing to bend those rules - especially if it means spending more time with her.
