Stealth and debilitating attacks make Sombra a powerful infiltrator. Her hacking can disrupt her enemies, ensuring they're easier to take out, while her EMP provides the upper hand against multiple foes at once. Sombra’s ability to Translocate and camouflage herself makes her a hard target to pin down.
While it doesn't do a ton of damage, her machine pistol has a large magazine. In addition to her Hack ability affecting other players (preventing them from using abilities) and health packs (making them unusable for enemies), she can hack Torbjorn's turrets. This doesn't damage or take control of them, but it does shut them down for a while, making it easier to destroy them. She also has a passive, Opportunist, that allows her to see enemies who are below 50 percent health through walls. While using her Thermoptic Camo, she is completely invisible to enemies--there's no shimmer to give her away.
