During the Shadowland crossover, writer Gregg Hurwitz and artist Ron Garney wrote a three issue limited series where Moon Knight deals with his brother in a final confrontation.

Randall is actually a member of the Cult of Khonshu, having been mystically enhanced with impenetrable skin and superhuman strength by Princess Nephthys.

Nepthys' "lunar treatments" granted him superhuman strength and external durability, although his internal organs were like those of a normal human's.

A young Randall Spector appears in flashbacks in the Marvel Cinematic Universe / Disney+ miniseries Moon Knight episode "Asylum", portrayed by Claudio Fabian Contreras.

As the latter survived, their embittered mother Wendy blamed him for Randall's death, which caused her to become abusive towards Marc, who consequently developed dissociative identity disorder and created Steven Grant to protect himself from her.
