Why is Wolf in the game and not Isaac from Golden Sun?

Seeing Olimar and 3D Pitt in pixels is kinda cool.

I would love to see some of these sprites on MUGEN. As for the portable DS smash having a 2d brawl would be amazing. make it like Jump ultimate stars nintendo!

Well, Wolf has a lot more history.  He's been Fox's rival for a decade and a half.  Isaac has only been in 2 games, and the last one was released almost 6 full years ago (in Japan).  Do we really need another swordsman?  Link, T. Link, Marth, Meta-Knight, and Ike not enough?  Wolf actually brought a fairly unique playstyle to the game.  His attacks are wild and primal.  No, he's not a Fox clone.  The landmaster is pretty lame though. 

Cool Image

i love that image *looks at sig*

Isn't there a stage in Brawl where the characters are converted to sprites? or am I mistaken? (there were 4 green warp pipes, one in each corner, black background and a red floor)

^That is just the classic Mario Bros. stage. Characters look normal on it.

mad skills

I see a lot of people are using the characters for their sigs. Also, a Smash Bros DS would be sweet and it better be announced soon.
