Future!Dean is a version of Dean five years into the future of 2009. In 2012 Lucifer's minions re-released the Croatoan demon virus - in this post-apocalyptic world, most humans have been reduced to mindless murderous zombies.

In this future, Dean is in command of a resistance force at Camp Chitaqua, where survivors have gathered - including Future!Chuck and Future!Castiel. The Future!Dean never reconciled with Sam after they parted, and at some point Sam agreed to be Lucifer's vessel in Detroit.

Future!Dean tried to become Michael's Vessel, however it was too late because The Host of Heaven and all of the Angels had left Earth.

When Dean from 2009 arrives at Camp Chitaqua, Future!Dean takes him prisoner. Dean finds, that Future!Dean has become ruthless. After regaining the Colt, Future!Dean leads a mission to kill Lucifer, using his friends in a suicide mission to distract Lucifer. In a confrontation with Lucifer, Future!Dean is killed.

Note: there is mixed opinion amongst fans as to whether the future shown here is "real" or merely constructed by Zachariah to persuade Dean to become Michael's Vessel
