Created by writer Stan Lee and artist Jack Kirby, Space Phantom first appeared in The Avengers vol.
[7] The Space Phantoms were originally various beings who became trapped in Limbo, were transformed into monsters and rendered amnesiac by its effects, and were conditioned to become servants of Immortus.
During a journey back in time to 1873, a trio of Space Phantoms was caught impersonating the Gunhawks and the Black Rider.
[9] The Space Phantoms were previously said to have originated on the planet Phantus in the Phalbo system in the Milky Way Galaxy.
[10][11] Immortus traps individuals who become lost in Limbo, and due to the nature of that plane, they begin to forget their former lives and change into misshapen beings.
The Space Phantom battled the Avengers, but was shunted back into Limbo when he attempted to mimic Rick Jones, who was then linked to Captain Mar-Vell.
[17] A Space Phantom was used as a pawn by the Young God Calculus in a scheme pitting Spider-Man against the Avengers.
