By the power of Grayskull...Turtle Power!

When the Teenage Mutant Ninja Turtles came across Krang and Shredder making a deal with some otherworldly 'demon-mage' named Skeletor, things got hella-weird and they ended up in ETERNIA! It turns out, when you mix Ultrom mutagen with demon magic you get a nasty purple poison-and it's brought Eternia to the brink of chaos. So, Leo, Raph, Donnie, and Mikey are teaming up with the Masters of the Universe to kick some blue boney butt. The only problem is...He-Man is missing in action.
