Mighty Morphin Power Rangers/ Teenage Mutant Ninja Turtles II #2 [PDF ebook] 

Casey Jones finds himself at odds with his former friends… and allied with Rita Repusla and General Krang! But has his allegiance truly shifted, or is he under some kind of spell-one that the Turtles and the Rangers can break? But our heroes have a lot on their plate: not only do Zordon and Alpha face certain doom, but an invasion threatens all of New York!
