@flipz: Hmm...I have to think about that. I know Electivire is one. Gallade is also a good one. For the last, I would probably say...hmm...I have to think about the last one. What are you planning for them? Also, do you play Pokemon?
You'd summon them using the Great Controller for an epic battle against the main villians, who have summoned several powerful bosses from other games (specifically Kraid from Metroid, Rayquaza from Pokemon/Super Smash Bros Brawl, and...*sorry, I can't remember what the last one was. I'll have to check my notes). Funnily enough, Blade also chose Electivire...but hey, since you're working together that means Jas won't have to draw as many Pokemon...which means it'll be easier for him and he'll be able to finish sooner.
I don't really play Pokemon; most of my Pokemon knowledge is limited to Super Smash Bros Brawl (which explains why Lucario, Pikachu, and Ivysaur are currently my favorite 3). I'm not really that "in" to the concept of most Pokemon games (though Collisseum was and still is quite tempting); I just find certain Pokemon cute or cool-looking. Which is why I don't like Giratina. Because he is just plain ugly.[/brutalbutnecessaryhonesty]
