Hmm...
If Warner Bros. does enter into an agreement with Toei, and Mazinger Z is among the properties hopping a boat to the U.S. as a result, this could cause ripples down the road...
With Warner Bros. Toei's partner in the U.S., Great Mazinger and Getter Robo won't be far behind, which means no Ronin Warriors or Starvengers as we know them. This is going to cause fierce butterflies involving Marvel-Sunbow and the partnership of Hasbro and Takara in the creation of a certain famous robotic toy franchise of the Eighties, with reverberations felt today...
I wonder, what if, say, Jay Ward Productions, looking for hits of their own, starts sniffing around the Land of the Rising Sun, and especially Toei's rivals Sunrise and Tatsunoko, looking for the next big hit after George of the Jungle and Dudley Do-Right, and discovers, say, Combattler V and Voltes V, rewrites the dialogue scripts to make them two halves of the same series, and thereby turns them collectively into a big hit on this side of the pond that jumpstarts the Eighties Mecha Explosion three of four years early. It could be Jay Ward Productions' biggest hit since Rocky and Bullwinkle. Then, with executive producer Nagahama Todao having bought the farm, Jay Ward turns to the next project of Nagahama's understudy, one Tomino Yoshiyuki, and his idea of a young boy falling into the cockpit of a cutting edge prototype on the eve of war in space...
And of course, even more interesting will be the concepts of American studios like Filmation, Freling-DePattie, Ruby-Spears, and Hanna-Barberra that are inspired by these developments...
