That Pokemon is really interesting, especially with the anime which sounds miles better than what we got. Though I don't subscribe to the theory that Giovanni is Ash's father I like what they did with it and the league challange with Giovanni being the champion and disbanding Team Rocket, not to mention Mewtwo being in a post season movie sounds 10 times more awesome than the First Movie to me. Oh if only those things happened instead of the stupid crap we got.
Though I do wonder why exactly Drowzee and Hypno were erased and why their replacements became Psychic/Fire, besides the puns, but I would like to see art of them since they still sound awesome like Plesia does, which is saying something since Lapras is pretty damn awesome. Molebore and Molecrush do kind of sound meh to me though, interesting for the concept but the names are boring to me. But I really like Marowak evolving into Kangaskhan and the names for the Nidoran are freaking adorable and wish those were canon.
However I'm not sure about the pirate, everything about her seems very out of place and out of nowhere, especially the name. I would have rather have Team Rocket attack the SS. Anne in the games like they did in the anime. However though I also don't subscribe to the theory that Blue's Raticate died I did like what they did with it as well.
I'm really curious what would happen in the sequel.
