Sure, you can use whatever.
Also, I've been getting a lot of requests for Saix. Do you people think he would make more sense over Ike, since he's a heavier character, or should I just stick with Marth? I haven't made an Ike vertex yet, so I don't really know what is and what isn't possible with him.
And finally, would more people want me to do a Saix or Axel first? I'll interested in doing both eventually, but if it's clear that one is in far more demand than the other, I'll try to make it a priority.
I say you should make Saix first but on another note who would you make Axel on? Link? I mean maybe you could use the edgemaster thing or something.. Axel would be epic pwnge no matter what. Also make saix on ike definatly I would love to play Saix Vs. Xemnas Vs. Sora Vs. Mickey(once hes out)
