Vasquez is an agent of the D.E.O. and a close collaborator of J'onn J'onzz, Alex Danvers and Supergirl.


Hunting Vartox

After they obtained a fragment of Vartox's axe, Vasquez and Alex Danvers used the obtained info on the object to hunt Vartox. Vasquez later informed "Hank Henshaw" that she found the Valeronian, on his way to National City. The director sent Supergirl to dispose of Vartox, and Vasquez watched.[1]

Red Tornado accident

Vasquez assisted as Supergirl battles Red Tornado and, later she showed a video of Maxwell Lord to Supergirl, where he, to his own advantage, blamed Supergirl for the android's rampage.[2]

Exposure of J'onn J'onzz

When Hank Henshaw was revealed to be an alien named J'onn J'onzz, he was taken away for questioning. When Kara asked Vasquez to shut down the dampening technology used to prevent her from eavesdropping, she apparently refused, but Vasquez deliberately left her post open, so Kara could listen in.[3]

White Martian infiltration

Vasquez was there when the base was locked down by J'onn J'onzz. She and the rest of the agents had to figure out who was really a White Martian. So she held her hand out to the fire and proved to everyone that she wasn't really a Martian.[4]

Behind the scenes

  • While the first name has never been seen on screen or in the credits, the actress who portrays Vasquez, Briana Venskus, believes that Vasquez' first name is Susan.[5]
