He-Man / TMNT: Turtles Of Grayskull #1 is the crossover that any reader who lived in the 80s could hope for in this unique crossover event. In this initial issue it is evident that Seeley and Williams are big fans of both properties. It will be interesting to see if the story continues to avoid the tropes common with this type of inter-property crossover event. Read Full Review

Plot
This first issue without preamble shows you the Ninja Turtles in Eternia uniforms, with a brief summary explaining that Krang and Shredder traded Skeletor mutant ooze for magic. Leonardo, Raphael, Michelangelo and Donatello contact Splinter and April O'neal to bring them up to date and tell them that they are about to go to an important battle at Castle Grayskull.

It is a key battle because He-Man disappears, so Mat at Arms brings all the cavalry to fight against Skeletor's mutant army. This battle has a twist when apparently He-Man transforms into a mutant with uncontrollable rage.

But the battle is stopped by Renet who comes to help stop this temporal disaster, but what she does is that they go to another alternate era where they are in a gladiator arena and He-man is the main star.

This comic has epic action sequences, where the mix of the characters' universe is not only with their presence, but with their suits and weapons, making this crossover organic and fluid in a sea full of nostalgia. The balance between war techno-fantasy with street criminal fighters is brilliant.

Michelangelo in a blonde wig is the icing on the cake of a good comedy.

Art
It is very organic and full of mesmerizing details, with textures that elevate the details and it feels like seeing the art of the MOTU and TMNT action figure boxes.

There are a series of splash pages that awaken the nostalgia of those who played with those action figures as soon as they came out, seeing all these characters together is a dream that I didn't know I needed to come true.

Summary
The Ninja Turtles go to the aid of Eternia when its most important warrior He-Man mysteriously disappears and Skeletor uses the power of the mutant ooze to boost his army.
Excellent crossover that we didn't think we needed with so much fervor more
