I want to see a story that makes all Overwatch characters forced into other characters' roles.
Reaper as Mercy, Mercy as Reaper.
Tracer as Reinhart, vice versa. Something like that.
Would be interesting lol.
It's really out-there, but Tracer could play Rein's role if she went full anime. Hell, she can be a sort time mage.
Reinhardt has a shield to defend his teammates? How about a big, isolated sphere in the space-time continuum that stops/freezes the travel time of any enemy bullet/bomb/whatever that touches that sphere?
Reinhardt slams his hammer to the ground to stun enemies? Try putting the chronal accelerator to overdrive, freeze all enemies within an AOE, and have you and your teammates pull a Za Warudo (minus the steamroller) until its duration is over?
