No, Hero got released because for months if not over a year they told him to get into better shape because he had no tone whatsoever. So, he doesn't do any of that and continues to look like he has AIDS, so they released him.
It's not a radical transformation, but Steen definitely added muscle and lost some fat. Easier to get by as a fat guy because of your "power" than it is to get by with being skinny and having girl arms.
