Thanos (Marvel Zombies)

Thanos sent the Black Order to Earth to retrieve the Infinity Stones found there, unaware that the planet was infested with zombies. After collecting the Infinity Stones that were in space, Thanos himself went to Earth, unaware the Black Order had now also been zombified. At some point in his attempt to collect the Time Stone, Thanos was zombified, arriving in Wakanda soon after.
