Leonardo would say that he's simply a humble turtle trying to do what's best for his family, his people, and the world. He wants to leave a positive influence and save future generations from the wretched clutches of the bloodthirsty alien race, the Kraang. The slider would do everything in his power to make sure the ones he loves are safe and sound, even if that meant sacrificing everything for it. He never had children but he seems to be adopting strays left and right! He loves being a mentor.
