Which superhero flies with giant wings and fights with a mace?

That sounds like Carter Hall, the original Hawkman! He's a DC Comics hero who uses giant, natural wings (usually made from Nth metal-enhanced feathers) to soar through the skies, and he's famous for wielding ancient weapons in battle — including a mace — thanks to his background as a reincarnated Egyptian prince. Hawkman first appeared in Flash Comics back in the Golden Age and has remained a fan favorite ever since. If you want to dive in, look for the classic Flash Comics issues or more modern series like the Hawkman solo runs!
