Leonardo is the leader of the Teenage Mutant Ninja Turtles team.
After Astronema feels they failed one time too many against the rangers, she orders Elgar to fire the Dark Fortress' Satellasers at the sewers of New York City, causing the five Ninja Turtles to teleport out of the sewers. When the Space Rangers are having trouble fighting Electrotramp, the Ninja Turtles appear and effortlessly destroy the monster, gaining the Rangers' trust. After being taken to the Megaship, Donatello starts hacking into its computer, turning DECA against the Rangers and allowing Astronema to board the Megaship. Things looked bleak for the rangers, until the Megaship flew through an electric storm, lifting the Turtles from Astronema's brainwashing. They subsequently turned against her and teamed up with the Rangers in a brief battle against Quantrons. After their victory, the Rangers offer the Turtles to bring them back home to New York. But before going home, the Turtles went for a small ride on the Galaxy Gliders.
