Nah, just Ridley. Meta Ridley is cool, but too Metroid Prime exclusive. Since the Metroid Prime trilogy is over and we probably won't be seeing him again, it doesn't make sense.
Same goes for Omega Ridley, only he's less epic. He's purely about Phazon, and while that was cool for the Prime series while it lasted, it should not have gotten to Ridley. Prime 3 is over, and since Phazon is gone, Omega Ridley is no more.
Ridley has had the most appearances, and he could represent Meta and Omega Ridley as well. Possibly alternate costumes for him, in fact. The only game Ridley hasn't been in is MP2, and I THINK Metroid 2. I've not gotten very far in that game, so I THINK it's just Metroids but I haven't researched it so I could be wrong.
Plus, if we have multiple Ridleys, we won't have room for Dark Samus and the victor here.
Thank you!! I respectfully disagree with what you're saying, but this is the most well-reasoned, non-flame-involving argument I've ever heard against Ridley. And the fact that you don't want him in because it would make him less epic. That's a good point, but...Metroid needs another rep and Ridley is the only one I see fit to do so. Dark Samus has made an appearance in two games, a cameo appearance in one (100% ending of Metroid Prime). The hunters (all of them) have been in one game, although I guess if that ship at the end of MP3 is Sylux's, that's sort of a cameo appearance for him. Plus, Metroid Prime Hunters wasn't a real Metroid game and, while I like Spire and Kanden (I agree with you there; he's another one of my favorites, and he has a nice story behind him. A little bit like Mewtwo, actually...), they just don't deserve to represent Metroid in my opinion. Even Zero Suit Samus doesn't have a place if you ask me, because ZERO SUIT Samus had a half hour appearance in Zero Mission, and then what, 3 ending apperances? It's just an alternate of Samus anyways; it doesn't count as a rep if you ask me.
Ultimately, I see either a Metroid (ugh...no generic characters), Kraid (waay too big), Ridley, and Space Pirates (again, generic) as being fit to have a spot. A Space Pirate would be awesome, actually, but I can't see one single Space Pirate that could represent them all. Weavel is supposed to be a Space Pirate, but doesn't look like one, nor has this fight to the death with Samus ever been in a game before. The Omega Pirate has had a one-time appearance, so again, no. Ridley may be big, and making him playable may be downgrading him, but on the other hand, he is probably the general of the Space Pirates (there have been conflicting things whether Mother Brain or Ridley is), he would be a great rep that DESERVES to represent the Metroid universe, and would be a villain to even it out. They've conquered challenges before; Pokemon Trainer, Bowser (I know you said don't use that argument, but despite the fact that he changes sizes every game, he has never been that small, except for maybe in the first game; and in that case, Ridley was that size in the first game too.), Ice Climbers, ROB, Zero Suit Samus, and coming up with movesets for people like Zelda and Captain Falcon. Not to mention the biggest challenge of all; finding a way to put tons of famous Nintendo characters into one game. If they've tackled all of these challenges successfully, I find it hard to believe that what Sakurai says is true about Ridley;
I just realized something; the Metroid games have ALWAYS been about Samus. Samus alone. Samus against the world. As such, I've now spontaneously realized that that's how it should be in Smash Bros. Samus against the world.
I still see Ridley as most fit as a rep, so he's still got my vote, but I'm fine without another Metroid rep.
Everything in the blue-ish color is to let you know that I still hold those arguments, but what I just said is what's most important.
