A space-going hero named "Captain Comet" who saves the Earth?
Plus, he's drawn by Al Williamson and Frank Frazetta?
Sign me up!
Note: he's not DC Comics' mutant mental marvel...
...but a character who only appeared once, in 1953, two years after DC's space hero debuted in Strange Adventures #9, and would continue as an ongoing strip through 1955 (usually getting the cover slot)!
The Captain Comet we've just shown you was more a Flash Gordon / Buck Rogers-type hero, set in the future, battling interplanetary threats with fists and ray guns.
Appearing in the first issue of Toby Press' anthology title Danger is Our Business, he obviously was meant to be an ongoing character, but there was never another appearance, except for a reprint in 1958.
Did DC issue a "cease and desist" due to trademark infringement?
We'll never know...
