She’s based on Cammy
Thanks to creator TheJamk, Overwatch makes a surprisingly fitting appearance in Street Fighter V by way of a Cammy mod. Yep, someone altered Cammy’s parameters to craft a Tracer skin, and it not only fits the art style, but it looks fun to play as well.
As the “mascot” of the game of sorts according to Blizzard, she’s shown up elsewhere too, like in Heroes of the Storm. Blizzard is likely thrilled with the level of popularity that the series has reached given that it’s a new IP. Zangief as Reinhardt next, modders?
You can find the Tracer mod here.
