Same as it ever was
One of the most famous episodes from the 2003's Teenage Mutant Ninja Turtles series is "Same As It Ever Was". Donatello gets teleported into a dystopian future, where Shredder has taken over and most of his family is either dead or estranged.
The shockingly dark and captivating plot of the episode has made it a favorite among many fans, myself included. As a tribute, I wanted to do a piece fashioned like a movie poster.
