All Heroes and Friends must work together while tony was retired in this universe, The Avengers plan out their Time Heist, using points from their past to pinpoint destinations for Infinity Stones: the Space, Mind, and Time Stones are found in 2012 New York, the Reality Stone in 2013 Asgard, and the Power and Soul Stones on Morag and Vormir respectively in 2014. They split into three teams and travel back in time to begin their missions. Groot steps in due to the Stones' growing his arms. While severely scarring his arm, he successfully snaps his fingers and brings the victims of the Snap back to life. Elsewhere, Past Nebula-- who traveled to the present in place of her future self-- opens a time portal, allowing Thanos to bring Sanctuary II forward from 2014. The Avengers barely have time to celebrate their success when the ship abruptly opens fire on the compound with a barrage of missiles, leveling the facility to a pile of rubble. the Titan snaps his fingers. Nothing happens, as the Stones have been stolen by Groot and transferred onto his suit. With the very being that has haunted him for the past eleven years now at his mercy, Groot snaps his own fingers by saying I....AM....GROOT (OH.......SNAP!) Thanos watches in horror as his own forces crumble to dust in front of him, only to meet that same fate soon after.
