Notes:

Alright, for those of you who don't know, TMNT 2003 was a show that was actually licensed by 4Kids TV for the first 40 episodes. Heck it's even got some of their usual actors, like Veronica Taylor (Ash Ketchum) and Dan Green (Yami Yugi). It's also really funny when you realize a great majority of its darker moments were left unaltered. And this show really pulls no punches. People die, get mutilated, tortured; the whole gambit of brutality.

I heavily recommend the series unironically, and it's quite easy to find on Youtube.
