I recognize the information is doubtful due to it's nature, and I actually have zero way of proving anything, the only thing I can say is put it in the back of your mind, and revisit it as information comes out, or in other words let time do its thing.
For people asking about tilts and move sets, i'm a casual gamer, actually I wouldn't even really call myself a gamer by any stretch.
I've had a lasting fondness of smash bros, pokemon, and dbz since childhood so i've always kinda stayed current with it, and used sites like this to get little nods of information.
When I was playing the demo I wasn't dissecting it, with the intention of regurgitating every little bit I saw.
I picked it up and wanted to beat my brother, and have a bit of fun.
I figured "hey, these guys might appreciate some info, I lurk it enough, ya know"
So I passed on a few notable things I remember during the match, some of which I ran by my brother to make sure was correct or coincided with what he remembered, in case I was wrong.
I didn't really play brawl, like I owned a copy but didn't nearly play it as much as melee or 64, different time in my life, didn't really play games as much. Like I don't even know what a tilt is, lol, needless to say i'm experiencing a bit of culture clash with you guys.
Take the information I gave you with a grain of salt, it's all you can and should do, frivolously debating and trying to debunk or prove it is rather silly.
I'm not offended or anything, like I get it, so if your reading this like i'm defensive, i'm really not, i'm just laying it all out on the line, like here's the information, take it as it is, what you get is what you get, simple, but like i've said it is what it is. I was just trying to be informative but if your taking it as like some conspiracy to debunk a wanted character, then just leave it alone lol, don't over think it.
Take what you can from it, and move on until it's relevant again I guess.
