- This version of Gargantos was inspired by Shuma-Gorath, but Marvel Studios cannot legally use that name due to it having originated in Robert E. Howard's 1967 short story The Curse of the Golden Skull, and thus being owned by Heroic Signatures. Rather than negotiate with Heroic Signatures to license the name Shuma-Gorath, Disney opted to call the MCU adaptation Gargantos instead.
