El Devorador
El Devorador is the monster at the centre of The Vanishing, the free Stranger Things crossover mission. It is the Demogorgon from the show, renamed by the Soviet Lock Project that studied it.
El Pollo Loco
El Pollo Loco is a drugged-up fighting rooster you battle in Ramón's cave bunker during Spur of the Moment. It wears the spurs Ramón stole from Elvis Carballo, so this fight is personal.
