What if... Master Chief was in Brawl?

We've not debating IF it will happen, it won't. Question is: What if it did?

I wouldn't be so quick to ignore the possibility yet. There's still a lot of time for a Halo DS games to be announced and the more I think about it, I think it's still a decent sized IF but there's still a decent chance too.

-edit-
And I know Master Chief isn't huge in Japan, but he is huge in America.  They've already added some characters from Japan only games and that is what they've done in the past too, but what if they started thinking about the American audience too?  Like I said, adding Master Chief would make the game even more insane popular in America and bring in a whole new audience.  There would be lines of people lining up to buy the game and console just because Master Chief was in it.
