I figured this would be a good spot to place my first post, as the Pokémon Trainer intrigues me so much, well... I had to speak my mind!
First of all, the concept is fantastic. The anonymity of the trainer was a great idea.
In each game, you choose a trainer, and choose his name. Then (If you're at all like me) you spend the next 100+ hours as that character.
The inclusion of Pikachu (And subsequent pokémon after him) was inevitable, though I was always curious when the trainer him(her)self would make the scene too.
Speaking of that, as far as the 'Wild vs. Trained' thing goes, I see it like this.
Pikachu does fine on his own, because no one in the Smash world outright resists his Thunder attacks. He can use all the electricity he wants, and it'll always hurt everyone the same.
The trainer's job in the games is to make sure his pokémon know that simply using 'their strongest attack' is not always the right path. Which is exactly what he adds to his 'team' in Brawl.
While Pikachu can just outright attack, the trainer needs to consider which of his three 'man' team is best suited for the current situation.
And on top of that...
Having three pokémon in one character just downright rocks, especially when it's the first three starters. Talk about nostalgia, huh?
Now as far as different movesets go...
I would imagine that Squirtle would have some sort of water projectile (Water gun?), possibly Skull Bash (Used often in the animé I believe), and I would think Rapid Spin as his up B. I'm thinking along the lines of Bowser's Up B, of course.
He rapid spins a lot in the animé, right? Plus it is actually useful in the games. In yo face, spikes.
Ivysaur, I love the idea of a vine whip move that would work as some sort of get back move, along the lines of the Link's hook shot.
The idea of the charging up SolarBeam is fantastic too. Razor Leaf would be a nice projectile.
Charizard... Flamethrower, seismic toss, and flight are all great. Wouldn't change any of that for the world.
As far as the PT in the background on moving stages, I adore the idea of a Pidgeot carrying him around. Probably not going to happen, but whoever thought that up earns a gold star in my book.
This guy is quickly moving up my list as a possible new main.
