The reason that Mewtwo looks like Giegue is because Ape and Game Freak are the same company. That's right. The company that made Mother/Earthbound made Pokemon. Not the same guy, but the company.• I thought Mew and Mewtwo were labeled off as cats..for some reason. Don't ask me why about Mewtwo, I thought he was based offa Giegue.
• ....You might as well tell me right now that Dragonite isn't based off of the Item Bag of Dragonite, Braviary is secretly not a reference to Flying Man, and N's Farewell isn't the Mother 3 Love Theme.The reason that Mewtwo looks like Giegue is because Ape and Game Freak are the same company.

Though according to Chuggaaconroy fandom logic, the 3 beasts are hamsters. Though they look like cats. Though people call them dogs. How does that work?
Edit: Actually Ape is not Game Freak. Ape is actually Creatures. Still though they both worked on Mother and Pokemon, but APE is Creatures and that's why Mewtwo looks like Giegue.
