10 Alternate Timeline Movies The MCU Should Make
10. Stinger
In Avengers Infinity War, Doctor Strange saw 14, 000, 605 alternate timelines, and while we don't know in exactly how many of these scenarios the rat walked over the controls of the van to release Scott from the Quantum Realm, it's fair assume that in at least a few million it didn't. Thus, leaving Ant-Man stranded and assumed to be dusted by the snap.
This would leave Cassie Lang to grow up without her father, as she did in the five year time jump in Endgame. With her neighborhood now run down and her father gone, what if Cassie stumbled across some old Ant-Man equipment and decided to carry on Scott's legacy in his absence.
In the comics, Cassie deliberately exposes herself to Pym Particles in order to gain powers like her father and she takes on the alter-ego of Stinger. This could be a relatively grounded movie about Cassie trying to better her community rather than saving the universe. Kind of a friendly, neighborhood Stinger.
This could be the beginning of a path to a Young Avengers team up with the likes of Ty Simpkins as Iron Lad and Kate Bishop should she be introduced to the MCU.
