Along with several other characters, the Sinister Six were amongst those characters who became zombies in the Earth-2149 timeline AKA the Marvel Zombieverse. Not a lot is known about this version of the Sinister Six prior to the breakout of the zombie plague on this version of Marvel Earth, but it's generally presumed that they carried out much the same actions as they do in the standard Marvel continuity. In the Marvel Zombieverse, zombified versions of the Sinister Six characters attacked the mutant characters Wolverine and Magneto as they were aiding various people in taking shelter on a S.H.I.E.L.D. Helicarrier. Sandman, Green Goblin, Doctor Octopus, Electro, Vulture and Mysterio were all present as zombies in the attack, along with Venom.
