Isn't it time someone became a boss?

I know that characters like Kyo and Terry are like virtually fighting gods; they seem to defeat everyone who ever challenges them. Ok, since they're so badass, isn't about time they ascend into the realm of boss now?

Well, at least Kyo has in a way turned into a mid-boss, Kusanagi.

I think Duo Lon should be a boss character instead of a regular selectable character. I thought Sol Badguy could "BEAST" people down, but not like Duo Lon. He dosn't even need Roman Cancels. WTF!
