Watch the part of the movie at the beginning, where all of the trainers are at the dock and Officer Jenny and Miranda are explaining the situation. Fergus says, "All my Pokémon are water type!" That's not true. He has a Nidoqueen, which I believe is half Ground and half Ice.
OK, minor slip up, if it can even be called one.
First of all, I taught my Nidoqueen, Michelle, surf. It can learn ANYTHING I tell ya... =)
Secondly, a chunky kid like that probably doesn't want to waste time on a boring ol' police officer dressed like a meter maid so he generalized a bit.
Third, Ground and Ice? Where the heck did you get that idea? Nidoqueen is Ground and Poison. Nidor is the latin word for stench and plague. Nidoqueen is a poison rat, so it was aptly named, huh?
You don't believe right. Nidoqueen is ground and poison...why do you call yourself 'Pokémaster?' What is correct is that the lady is dressed like she's just came from 1313 in a time machine, and she is a liar. Don't forget TR braved the storm. She said anyone who braved the storm would become pokémon masters. Correction: She said it more like porAmoon machhests.
Well, they did brave the storm, but they weren't Team Rocket, they were Team Odin! So, they are Pokemon Masters so long as they are Vikings and Meowth is a Valkyrie. Lol.
He's a bit stupid then. Poison and Ground are crap against Psychic. And I think Water PokéMon are evenly matched, but would have to be on a higher level than Mew-Two. None of the trainers had any hope of beating Mew-Two! But it figures- none of them did beat Mew-Two.
You have to remember they thought Mewtwo was going to be a person and not a Pokémon, so they had no idea what they were up against. And a Quagsire is Ground and Water, no ice in there.
