It would be awesome if we fought a super buffed Mario... >_>

How about this then...

Captain Falcon

Maybe it's Petey Piranha. He seems to show up a lot these days.

That's very true. It'd probably piss me off a bit though.

Bowser? :P I don't actually think it'll be any of these, but hey, it'd be really cool.

That would be amazing, but I wouldn't get my hopes up.

Yeah, I guess we'll have to save our Little Mac vs. Captain Falcon hopes and dreams until the next Smash Bros. ... Little Mac better be in the next one. Pretty sure he will, too.

What about Bowser?

Edit: Majin said that already. Maybe he fights Rocky!

Apparently, this surprise will please all the Punch-Out fans.

So I think this is link to a Punch-Out game; thus the choices are:

- Mike Tyson: but it seems hard since he is in Fight Night

-Mario: but he is too small to be fightable in my opinion; and it would be hard to include him well

-Mr Dream

-Doc Louis Young

They are in my opininion the only ones likely to be the secret and so to please everybody.

Otherwise, Rocky would be fantastic
