Toxikinesis

Maya Herrera (Heroes)
Maya and Alejandro both seem to believe that Maya is responsible for causing the deaths of people around them. They believe that they need to get to New York, where there is a doctor who can help her. Since they have been reading a copy of Activating Evolution, they are presumably seeking Chandra Suresh.

When Alejandro finds Maya after she is kidnapped by some "coyotes", everyone else in the truck has died; their eyes have spilled black tears.

Maya's virulent ability manifests when she begins leaking black liquid from her eyes. Then, her guide to cross the border dies just like the coyotes. However, Alejandro is somehow able to reverse the condition, by gripping Maya's hands tight and praying. The guide comes back to life and flees, and all the black liquid is absorbed into Alejandro's eyes. Maya later learns to reverse the effects of her ability without Alejandro.

At long last, Maya's ability is taken away by Arthur Petrelli.
