Overwatch - Ze shipping is getting stronger

Headcanon: Dell Conagher, Grey Mann, and the Medic pioneered much of the technology used in Overwatch, which given that would place such work a full century before Overwatch, would be plenty of time to perfect it.

-Dell developing tech for automated sentry placements, and cyborg limbs, which are furthered by Torbjorn and Mercy.

-Grey Mann developing robotics, leading to everything involving the Omnics.

-The Medic developing healing technology, resurrection machines, and personal shield generators.
