BOOM! has done so many great things for the Power Rangers franchise. In addition to their amazing ongoing and standalone comics, they've had these crossover stories that just have fun. First there was the Justice League crossover and now Teenage Mutant Ninja Turtles! It's like playing with your 90s action figures, but with professional storytellers and artists telling the story.I enjoyed this book even more than the Justice League crossover because this story really leaned in. The new innovative designs are so cool! The Turtles as Rangers, new megazords, and more!The book opens with a classic feel from both properties and establishes where in the Power Rangers timeline this takes place. Tommy is the Green ranger, but he's not currently fighting with the rest of the team. Tommy is missing and where he's gone directly connects to the Turtles.This book takes place in a world where the Power Rangers and the Ninja Turtles both exist. I like the kind-of throwback to the television crossover. Donatello is even a fan of the Power Rangers. I expected there to be some dimension crossing, but I liked that they exist within the same world.When Tommy morphs, the Turtles recognize a ranger, but the Rangers thinks they're some of Finster's creations. This sets up great conflict that moves the story along. The pairings while fighting are so great. I love the interactions. The personalities of all the characters really shine through. Ryan knows them well.Tommy's character is expanded upon even more. His motivation is explained and some of his life history is delved into.Shredder meets Rita! Casey Jones appears. April gets an awesome costume! (with just a small modification) There is so much great design and artwork in this book.This book is so much fun. It feels very true to both of the franchises. There's even a potential for a sequel left open. I hope that happens. Or, at least, another crossover story. I give this book a 5/5.
