MASTERS OF UNIVERSE TMNT TURTLES OF GRAYSKULL (2024)

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.

The universe is in knots! Renet is doing everything she can to stop the Teenage Mutant Ninja Turtle and He-Man universes from getting all tangled up, but they're stuck in a time loop! And with He-Man and the Turtles on the Triceraton Homeworlds facing-off against the All-Star Team in the Tri-Sports Arena, things seem to be only getting worse...

The Teenage Mutant Ninja Turtles and He-Man travel to one another's universes in the hopes of untangling the Knot in the cosmos. But despite plans to avoid jumbling realties, they find themselves drawn to each other's friends and allies. Meanwhile, timestress Renet has found herself in the past-smack-dab in the middle of the Foot Clan's training dojo-where a mysterious student may have something to do with all this trouble...

THE MASTERMIND IS REVEALED! In the wild conclusion to this wicked series, we discover who has been tying the threads of the He-Man and Teenage Mutant Ninja Turtles universes together. He-Man and the Teenage Mutant Ninja Turtles find themselves facing-off against unthinkable mutations and chaos—but this time there’s no reboots, no safety net, and no rules! Can our teenaged heroes prevail? • Script by the critically acclaimed and New York Times bestselling writer Tim Seeley. • Four issue series.
