This has been bugging me for quite some time. I have played the ORIGINAL Pokemon games, Red AND Blue, respectively. Mew is mentioned in there. In the Cinnabar Mansion, there are documents on the tables. Reading them clearly states the discovery of a New Species of Pokemon. Mew. If you read them all, one will clearly state that Mew GAVE BIRTH to a NEW POKEMON. They named it Mewtwo. Henceforth, Mewtwo is the Child of Mew, not a clone, and Mew is FEMALE. Glad I could clear that up.
The game came before the movie, and in Red/Blue/Green it says Mew gave birth to Mewtwo, so I'm assuming it's a female. :|
But they changed the story in the movie and so without it saying Mew gave birth to Mewtwo, Mew could be seen as male.
But I will always say that Mew is a female because the games are more canon to me than the anime.
I think that it is in the show. But by some miracle it is not then a girl because it is pink, it's behavior is better suited as a girl, plus it's voice sounds closer to a girl. the reason I said a girl in the game is because in yellow when your reading the journals in the burned mansion it said mew gave BIRTH.
Very few people who answered this question know anything about DNA it seems. o_0 Sorry anime fan girls who ship Mew with Mewtwo in their Fanfiction, but Mew is a guy because Mewtwo is a guy. Mew and Mewtwo have to be the same gender, because Mewtwo was made with DNA from Mew. If Mewtwo had actually been born, then it could've been a guy or girl. However, since there was only one DNA and not two DNA from a guy and girl after having sex, Mewtwo would have to be whatever gender Mew is. I hope I explained that well enough, it's kind of complicated. As for the arguments that Mew is a girl, because it's pink, small and sounds feminine, I've seen guys that wear pink, guys that are small and disturbingly enough I've even met some guys with really high voices. Anybody who ships Mew and Mewtwo is shipping a homosexual couple, just so you know.
No offense to most of you, but you're kinda dumb if you think Mew is a girl... MY REASON: If you think Mewtwo is male, then Mew has to be male as well since they have the same gene. And just because mew acts and looks girly, its neither a girly girl or trying to be cute. Hope yall believe me now!?!?!
Mew is a girl because in the games it says mew gave BIRTH to mewtwo if you think mew is a boy because mewtwo is a boy and in the anime mewtwo is a clone how are you so sure mewtwo is a boy but not sure if mew is a girl so mewtwo could be a girl but I'm sure that wouldn't go well with many people because many people think men are best men are stronges ect but when they specificity how they usually have no reasoning
I think mew is a girl because she is so small and well,she's pink. Plus mew has always struck me as a girl. Besides mew is be super cute. Besides in my opinion mewtwo is a guy. Mewtwo is a clone,but what if the scientists made mewtwo a boy? Maybe in hopes of the mews making mewtwo's species you know a real one. You can think what you think but this is my opinion,so please no hate. ??
