A few quibbles aside, I've been very pleasantly surprised by how good this show has been so far, and it's great to see them begin to introduce a few of the old favorites like Leartherhead here. Casey Jones next though please!
Emerging from their hidden lair in the sewers, the Teenage Mutant Ninja Turtles visit the surface for the very first time and confront the wondrous and hostile world of New York City! They immediately face a group of thugs attempting to kidnap April O’Neil and her father Kirby. Failing miserably to rescue Kirby, the band of reptile brothers promise to help April find her father, and together, they learn the importance of working as a team. When the Turtles come upon a mysterious canister of mutagen, they realize the mystery of their existence is much bigger than they ever imagined. Now, with the proper ninjutsu training, and Leo as leader, the brothers are ready to face their worst enemies, including a race of extra-dimensional aliens known as the Kraang, a vast army of ninja warriors known as The Foot, and of course, the evil and ruthless Shredder.
Teenage Mutant Ninja Turtles airs Saturday mornings on Nickelodeon.
