>>114093697Hawkman just doesn't work when you get right down to it. It couldn't work in the 40s and his series was cancelled, didn't work in the 60s and his series was cancelled, and did not do too well in later eras either. He's just not that interesting to a wide audience. He has fans, the same way everyone has some fans out there somewhere. A flying barbarian guy with a mace that hits things just does not bring in tons of readers.
Most of the flappy bird guys never get a solo anyway, Most winged heroes are on teams and only appear in team books. The X-Men one never does solo anything, Dawnstar never goes solo, Falcon does not go solo, the winged people are always backup on teams that fly the non flying members to places.
