@CLOCKWORKIAN The 2003 cartoon series had them fight alien humanoid Triceratops. And a martial arts tournament in another dimension where they meet the rabbit from Usagi Yojimbo. But I actually like the colour-coded bandanas. The Nickelodeon cartoon goes further by giving them different details and even different shades of green.
@Ailurusf Ninja Turtles was never not "dark and gritty", but they are also silly. They were always meant to parody the dark 1980s comic like the stuff Frank Miller wrote in that era. The 2003 cartoon was also pretty serious, but still aware of its own silliness.
