Comic 72:Mewtwo Strikes Back is the first Pokemon Movie Based Comic in TARS, and 72 overall.
This is the first comic to have Mewtwo use his Melee artwork as a sprite.
According to the deviantart description, this comic was made right after Poyo watched M01 for the first time, and he also says he has watched all the movies. This means the 17th Pokemon Movie Poyo watched was the Mewtwo one.
Mewtwo says that most of the trainers at his island had weak Pokemon. According to Poyo Ride, he was on the island (offscreen) and had his Pokemon Cloned (Which Explains how Rayquaza got there.)
