Mighty Morphin Power Rangers/ Teenage Mutant Ninja Turtles II #4 [PDF ebook] 

The penultimate issue heats up as the Mutant Rangers are in dire straits, but a familiar mentor brings new allies to turn the tide! But the battle also rages in Dimension X, where the hero and villain roles continue to blur as they fight old foes and unfamiliar monsters. The Mutant Rangers shouldn’t celebrate too soon though, as their worst enemy arrives in a monstrous new form!
