The WORST episodes of Teenage Mutant Ninja Turtles

Every episode of Teenage Mutant Ninja Turtles ever, ranked from worst to best by thousands of votes from fans of the show. The worst episodes of Teenage Mutant Ninja Turtles!

Distinctly different from the grim, violent, and dark MIRAGE comics from which the Turtles originated, this version of the franchise has remained the longest running, and most memorable, version of all. Four turtles fall into the sewers and are befriended by Hamato Yoshi a Japanese man sent to New York who was forced to live in the sewers. One day he sees a strange green glow which transforms the four turtles into human-like creatures. Hamato (now Master Splinter) changes into a giant rat from the green glow and teaches the turtles the skills of the ninja as they team up with Channel 6 news reporter April O'Neil to battle against Yoshi's arch enemy Shredder and Krang, an alien warlord from Dimension X.
