Is that a Superman punch? That's a lunging/leaping roundhouse right. I consider a "superman" punch to be a straight left from an orthodox fighter when he's using it as part of a combination. Unlike a jab, where you don't use much body twist, if you throw a straight left after a right cross (instead of the usual cleanup hook), if you put body weight into it, it's becomes like a superman punch. Zab Judah and PacMan both use it from time to time.
