@hauket prompted me to do a Junkersona design for Overwatch and this is all I’ve got so far. 

I’d def be a support character. Maybe using AOE attacks because I have horrible aim. I thinking a mixture of Ana, Widow, and Soldier. Healing/damaging grenades as a main attack (but fired from a grenade launcher like Junkrat), small poison mines, and a healing field. Ultimate would be a large poison gas cloud that does damage over time like the mines, but a larger area, so it’s harder to escape the effect.
