For me, it would be Meta Knight's super move. It has that Raging Demon feel to it, and it's just freakin' badass.

"Know my power!"

^How could anyone not love that? lol

Link's super move is pretty cool, too. 

Even though I can't stand using Ganondorf. I love his final smash. And pretty much anything DeDeDe does is aces in my book.

Well, pretty much every moves Ganondorf can pull off. He's just sooo good! Too bad the online service sucks so bad I can't play well with him against other people (actually, versus 1 or 2 I always win, but versus 3 and 4 it all depends if there are some over-powered Smash abusers in the match, for example Ike... b*tch!). I'd show everyone what a great Ganondorf player can do! =P

 lol! Ike and Link are the cheapest characters in the game.

Dedede for the win. His B-up is so great. I don't understand how my friends NEVER dodge it! It must be because he launches up SO DAMN HIGH, and by the time he makes his descent back to earth, the other 3 fighters forgot about him. Then BAM!

His B-down is a ginormous ass-kicking mechanized hammer, half the time I can't use it effectively, but the most fun comes in simply scaring the shit out of everyone as I walk and JUMP around with a huge, presumably jet fuel-powered, fully charged mallet.

His B-side? Waddle-dees for everyone! Some big slow guy like Dedede can't extend his reach to you way over there with his humongous hammer alone? Throw some Waddle-dees over there! Hell, throw some spike things once in a while, and even BOMBS and SMASH BALLS. Yes. The magical coat of Dedede stores every item known to man.

Did I mention he can swallow a man whole? Yeah, he can.

Marth's FS - soooooo good!

 Nah, don't forget Fox's (or Falco's or Wolf's) *takes a deep breath* over-powered-too-darn-long-what-the-heck-it's-not-over-yet Final Smash... And the Dragoon parts... Oh my god! @__@

 I also just hate the new way they changed some of the weakest attacks in Melee and made them the most casual friendly super powerful attacks ever. For example, run attacks are now more powerful than Up+A Smashes (or any other combination) for pretty much every characters, you can't really defeat your opponent with simple A combos (aerial A combos count too) so your best moves are now Smashes... But that's just cheap IMO, etc.

 Oh well, I guess I've still got to get used to the new engine. I miss some techniques from Melee, I really do. ;_;

Snake's running A, as well as his tilt A and standard A combo attacks are pretty awesome. I love just dashing back and forth doing running-A attacks with Snake, and occasionally laying trip and proximity mines everywhere. Love it.

Ummm i love that bomb from star fox .....its just so pwning hit it by accident on small stage everyone doomed !Throw it into ppl fighting watch them get blown sit back and laugh ....

I love Peach's final smash!!! There's something really satisfying about walking up to your helpless foe and hitting him with a fully charged side smash which send him flying away or kills him. And then while he's not there you're free to eat those yummy peaches!
