I really did like Captain Falcon's as well. Olimar turning around to see Captain Falcon and the Mute City music coming on was awesome. Then he killed all the Pikmin, Hilarious.
I actually didn't like Meta Knights. I mean, he just came flying outta nowhere, and then fought Marth. First of all, with the Mach Sword he would've kicked Marth's butt. No way anyone could even react to that. Second off all, where did he come from, around the Subspace Explosion?
The reason Sonic's entrance still puzzles me is that he would have been vaporized by Tabuu's pulse from his wings had he been in subspace prior to the group entering. Which means he would've had to just come in right then. I think he and Snake should have had something together, since they're both not from Nintendo. He's random presence in subspace is stupid. Anyone could ahve damaged Tabuu's wings. Kirby could've dragooned 'em had he showed up in the end, Cpt Falcon could've flown Blue Falcon or the Flyer right through his wings, it's not that great that he did that. All it shows was that after everyone else did the work, he came in and now you give him all this credit. What I'm saying is. Just take one character and leave them out til the end and they could've done it. Sonic just happened to be the last character put in.
And by the way, "if you read the story": Go to the section called Tabuu's Off Waves. Apparently they have the ability to turn anything into trophies at a great distance.

Making Sonic's into not only stupid, but impossible.
