Brawl - Dedede/Ike

(I like weapons!)

 BRING NESS BACK =((((((((((((((((((((((

I loved Ness.

PK Fire annoyed DK Punch spammers, and his grabs were so spammable that I couldn't help but sit there and laugh.

Damn, now I want to play the game again.

*Blows dust off N64*

That is so obviously Luigi

Kirby
Marth

All true.  Ness was my first character I felt I'd mastered and my favorite as well.  Kirby came in a very close second though.

its luigi, its slimer and taller than mario, it has its legs curled but it is really him, how could you say its obviously mario. Its the green marvel, the greatest sidekick of all time.

No, look at the picture above it. Mario is in the picture when the smash starts, so why would Luigi suddenly be the one affected? It quite clearly is-a Mario.

The angle may have you confused.  It looks slimmer than it is because you're looking at a 45 degree turn of his body, not straight on.   

And there's only 4 in a brawl.  Metaknight, Mario, Link, and Kirby are shown in the sequence of pictures in the final smash (the one that works).  So no, sorry, not confirmation of Luigi.

Updated:

That's Mario cebrian. Why would Mario transform into Luigi with a Final Smash? :P

Also, my favorites in the orignal were Pikachu, Link and Mario.

In Melee would be Captain Falcon, Mario, Marth and Mewtwo.
