You know, everybody’s making jokes about the McElroys making Type: Null as an Arceus knockoff, but really I think that the Poekmon-universe-equivalents of them McElroys would probably have been much more likely to have worked on the Mewtwo cloning-project.
Like, think about it, who else do you know would look at the lanky; grotesque form of Mewtwo; compare it to the tiny cat-fetus-god Mew, and say “You know, this looks just like Mew. Tip to toe this is a Mew. Universe creator Arceus quits in disgrace: they’re just better at Mew than I am.” ?
An anonymous user requested that I upload the concept art from Myuutsu no Gyakushuu after reading this post. I’m sorry about the poor image quality (I took these with my phone). The scans in that old post are even older – I made those scans seven or more years ago, stored them on online storage, and since then no longer have a scanner.
To further answer the anon’s question, I don’t know where to get the concept art now. I received the concept art as part of a package with the Gyakushuu VHS fifteen years ago (omg I am old). It’s on a poster. One side is the concept art and the other side is, strangely enough, the dub promotional poster of the movie. The package also came with the English promo Mewtwo card for the movie. And the tape itself contains both the movie and the 10-minute short. There’s no subtitles; everything is raw.
I got the VHS from an online store that is now gone. Sorry. You can probably find it on eBay or something like that, though.
