OW Hero: Zarya

This can go both ways, but I would say Sombra would be more likely to win a 1v1. For one, her hacking can prevent Zarya from throwing up her bubble and her teleport can get her to a better position. Plus, Sombra's weapon has a bit more range on it and can do a bit more damage, unless Zarya was able to charge beforehand. It really depends on if Zarya's alone or not. If not, Zarya's obviously more likely to win.

As Zarya, stick to your team and only engage Sombra if you are confident you can take her out.
