As my sig says...
Classic Mewtwo shot first.
And for the record, if you're a scientist on Team Rocket's payroll, you're classified as "evil." Thus, they were
both created by "evil" scientists. Also, in the original Japanese dub, Mewtwo wasn't "evil." He was portrayed closer to that of a confused child and even had childlike mannerisms. The English dub made him evil.
And for fun, here's the temper tantrum I threw on IRC...
<TrakNar> Okay, what the hell. So, I got some information on the new movie, and the Mewtwo in that one is indeed a different one created by different mad scientists.
<TrakNar> One of the biggest things about Mewtwo's story was that he was the ONLY FRIGGIN' ONE. Now, there are TWO??
<TrakNar> So, they couldn't use the one from twelve years ago who was already PATROLLING A CITY, they had to make a NEW ONE?!
<TrakNar> GRRRRAAAAAAAAAAAAAHHHH!!

<Jello> I didn't even /know/ there was a new Mewtwo movie
<Jello> wtf.
<Jello> and somehow they create the exact same species
<Jello> and on that outrage, I think I'm off to bed
