Yenifer Molina (Detective Pikachu) has apparently joined the cast of Doctor Strange in the Multiverse of Madness. This comes from a Twitter page called @DrStrangeUpdate as they uncovered the actresses role.
For those unfamiliar with the character, Gargantos was a sea-monster at the command of Naga. Naga is a Lemurian emperor who wields the mystical Serpent Crown, which gives the wearer superhuman strength, the power to read and control minds, as well as many other abilities. Gargantos first appeared in X-Factor (1986) Annual #4 and again in The Sub-Mariner (1968) #13. Both issues have the sea-monster battling Namor the Sub-Mariner.
No official word has been disclosed.
