Ok so, I've got an idea that I've already made it's own thread to discuss a bit but I want some more opinions as I've already got a
few bullet points.
In the late 70s Marvel and Toei made a deal that allowed them to use eachothers characters however they saw fit. Marvel did this to create the Shogun Warriors comic (
https://tvtropes.org/pmwiki/pmwiki.php/ComicBook/ShogunWarriors) while Toei used it to make their
legendary Spider-Man series. The basic PoD would be that during contract negations an agreement is made that gives the two companies a little more direct oversight on projects pertaining to how each uses the others properties creating a closer overall working relationship with the two and changing a number of things.
The affirmationed bullet points:
Battle Fever J is created as it was originally envisioned, a captain america adaptation but for Japan with Captain Japan eventually getting to appear in thr comics and fight alongside the og Captain at least once.
Stan Lee's idea to do Power Rangers years before Saban ever does with Taiyou Sentai Sun Vulcan goes through resulting in the West getting a tast of Tokusatsu in the 80s rather than 90s, with him specifically making it a package deal with A dub of Toei Spider-Man that has a much stronger appeal thanks to the West already having had successful Marvel Superhero TV shows (A Spider-Man show already having been one) and the two forming a America equivalent to what otl Japan would call the Super Hero Time block.
Through butterfly effect Philip Michael Thomas dies in a freak accident before Miami Vice and the show never ends up getting off the ground.
From what I've found multiple sources say the Pryde of the X-Men pilot was animated by Toei and long story short in this timeline Marvel has it aired in Japan first as proof of concept before bringing it over to the west making for a slightly different X-Men animated series.
A bit into the timeline DC seeing Marvel and Toei's joint Sucess seeks out a Japanese partner of it's own and finds tsuburaya productions resulting in the TV movie Superman vs Ultraman
Saban, thoroughly kicking himself for not thinking of it first ITL after seeing the Sucess of Marvel's Super Sentai adaptation he aproched Toei as they were preparing to send Sailor Moon to the west with an offer, the result? A rough equivalent to Toon Makers Sailor Moon being the majority of American children's introduction to the story.
So, any other potential butterfly's I might want to add? Comments on what I've got so far? I'll take anything.
