Widowmaker and Sombra are quite different. They might be on the same team but Sombra is a very quippy, cheek and smug woman while Widowmaker is the exact opposite being patient, ruthless and emotionless.

Widowmaker has Yellow Eyes, Long Blue tied into Ponytail which reaches past her hips and Purple-Blue Skin.

Sombra has Purple Eyes, Shoulder Length Dark Brown Hair with Purple Highlights at the Ends with her Left Side Shaven, and Tan Brown Skin.
