I tried labeling characters from Overwatch with some of the characters in Heroes of Beacon based on either personality, weapon arsenal, fighting style, or simply random reasons:

Soldier 76 Abel
Lucio Lucas
Tracer Jack
Mercy Sepia
Widowmaker Gratia
Winston Robert
Pharah Bianca
Junkrat Lauren
Roadhog Amy (just because of lauren xD)
Reinhardt Trad
Genji Shiro
Hanzo Sangue
Mei Beryl
Zenyatta Napoli
McCree Benjamin
Zarya Krysanthe
Ana Cian
Bastion Cobalt
Reaper Sapphire
DVa Vega
Sombra Skyra
Torbjorn Gren (a gigantic one o-o)
Symmetra Diamond

Mrs. Volskaya Estelle (and Emerald as her daughter xD)
Hollywood Car Omnic Sterling Johnson
Athena Sand
Doomfist(?) Oswald

I couldn't fit everyone in (like Yue ;-;) unfortunately but I tried!

EDIT: I switched Gren and Robert because Rob has glasses and Gren is tech-savvy! :D
