8 Best Quotes From Teenage Mutant Ninja Turtles: Mutant Mayhem
TMNT: Mutant Mayhem is full of fun, silly lines that will stick with fans for a while after watching it. Here are just a few of the best quotes.
For some, that may be Leonardo. Chosen by Master Splinter himself to lead his brothers, he keeps the Turtles grounded in the present moment, or at least as grounded as four adolescents can get. His relationship/rivalry with Raphael is also the stuff of legends, having escalated on more than one occasion. Here are quotes from his more memorable moments in the franchise.

Nickelodeon bought the rights to the Teenage Mutant Ninja Turtles from the Mirage Group and 4Kids Entertainment in 2009. This left the franchise in a precarious position. Turtle fans would not be disappointed, though. Nickelodeon’s premiere Ninja Turtles cartoon in 2012 would deliver a charming blend of comedy, character development, and epic adventures.
One of the primary foes in this iteration are the Kraang, a race of brain-like aliens who pilot metallic humanoid exosuits. They also have a habit of speaking in the third person and in overly elaborate sentences. Leonardo has heard it so many times that he ends up incidentally emulating it himself.

While the child-friendly Saturday morning cartoon of the 80s introduced many to the Teenage Mutant Ninja Turtles, the characters first appeared in the independent comic book created by Eastman and Laird as a parody of Marvel’s Daredevil comics. Issue #1 opens with the four brothers cornered in an alleyway by members of the Purple Dragons gang, one of whom refers to them as wearing “stupid turtle costumes.”
Leonardo’s response tells new readers what they are in for. These weren’t just humans with superpowers or running around in bright costumes. These characters were an oddball creation, helping to set them apart from some of the more mainstream competition. This quote also puts a question mark in readers’ heads, making them wonder just exactly who these Turtles were.

The Turtles’ most recent battle with the Shredder in the 2003 cartoon left them badly injured and ultimately doomed without the intervention of the Utroms. This leaves Leonardo carrying PTSD and heavy guilt for nearly failing his family. To channel his anger, Splinter sends Leonardo to Japan to train with The Ancient One, who trained Splinter’s master.
Leo’s final trial in the episode is against a stone guardian who tells him he is weak, prompting flashbacks to their last encounter with the Shredder. Leo fights back, shouting, “I did the best I could,” and slices at its face, revealing a mirror image of himself. Here, Leonardo moves past his anger and guilt. He felt that he had failed his brothers when what he did not realize was that sometimes, even leaders fail. He did all he could for his family, and at the end of the day, that is all anyone can do, their best.

The Teenage Mutant Ninja Turtles’ big screen debut blends the light-hearted slapstick of the 80s cartoon with the darker edge of the original comic books. A heated argument between Leonardo and Raphael would see Raph departing from their temporary hideout in their friend April’s apartment. Soon after, a confrontation with the Foot Clan leaves Raphael in a coma, and the Turtles, April, and new ally Casey Jones retreat to a barn in the countryside.
Leonardo’s conflict with Raphael becomes a distant memory when his brother barely clings to life. During the days that Raphael is unconscious, Leo keeps a constant vigil over him. When he finally awakes and requests some food, Leonardo is overjoyed. Although the two get on each other’s nerves sometimes, Leonardo is just glad he is okay.
