The Greatest Teenage Mutant Ninja Turtles Villains Of All Time

September 20, 2012
Sean Astin has been a rebel, an underdog, a Goonie, and a hobbit. Next, he'll be a Ninja Turtle.

Specifically, he'll be providing the voice for Raphael in the new animated series of the Teenage Mutant Ninja Turtles franchise, which will debut on Nickelodeon on September 29 at 11am.

Being a child of the 80s and 90s, it doesn't take very much for me to get excited about anything related to the Turtles. That said, as much love as I have for the quartet, the characters I find myself most fond of are the colorful, bombastic villains that they came across on their adventures. Maybe it's because I'm secretly evil (!!!), or it could be a testament to the strength of all the characters throughout the franchise.

Whether playing with the toys, fighting them in video games, or watching them be foiled at every turn, the Ninja Turtles rogue gallery is something to behold. Here's our top five.

5. Shredder

The coolest of the cool. Whenever you saw Baxter Stockman, you knew you were in for a great episode. Although he was unequivocally a villain, he was also a weirdly sympathetic character, starting out as a pathetic former scientist until he was transformed into a mutant fly when Krang's attempt to discard him after he'd no longer been useful backfired. Combined with his scientific propensity, he became one of the Turtles' most difficult foes while also pursuing revenge against his former employers.
