As rejected Legion applicants go, Fire Lad actually has some decent powers, and they make for a neat visual; he breathes fire. The Legion turned him down because his power was "too dangerous and might cause accidental holocausts." I think that was just a nice way of telling him his costume sucked.
Designed by the Archduke of Squares, John Forte, Firelad's duds hit the viewer over the head with a "FIRE!!!" theme, including a fireball belt buckle that looks more like a pretty yellow carnation. My suggestion: dial that shit back a notch. Or two!
I've balanced out all that yellow, orange, and red with an equal amount of cool white. And I designed a nice, graphic torch symbol for him. I also like the contrast of the head-wrapping cowl and the punky haircut. It's an edgy look to go with his carnival sideshow powers.
