Captain Comet is a particularly obscure time capsule of a character. Technically, while DC has plenty of characters with latent 'metagenes' that activated at puberty, mimicking Marvel's mutants, Adam Blake is their only actual Mutant. He was born the next step in human evolution as understood by 1950's era science fiction. This meant that he had a entire slew of extremely advanced powers, making him a sort of amalgam of early sci-fi character concepts. It was a solid concept, but it also meant that he was never well-defined enough to really take hold in the DC universe, despite being a regular supporting character in the early Justice League.

For some time, you really only saw him in the pages of L.E.G.I.O.N. in varying roles, including leading the team for a time, although he was always depicted as a sort of outsider to the team as a whole. Eventually, he was featured in the Rann-Thanagar War, earning a resurgence in popularity that led to is starring role in Mystery in Space, a miniseries showing his adventures on Hardcore Station.

We're focusing primarily on his role with L.E.G.I.O.N., showing him as a freelance character working with interstellar law agencies but never fully allying himself with them. Eventually, he will come into conflict with Lady Styx when she 'kills' him and begins using his corpse to clone new psionic warriors, leading to him joining Adam Strange's Omega Men, giving them an unbelievably powerful frontline fighter.
