Valentina Resnick-Baker

"Val", hero name, Summit, was one of the five astronauts in The Event that granted her superpowers of plasma fusion or "the power of the stars" as she mentions that's controlled by her emotions.

History
Raised in Iowa, Val was always very interested in space and with her supportive parents by her side, she excelled in school and became an astrophysicist and soon, an astronaut for Foresight being part of Project Icarus. Haunted by the hallucinations of her co-workers and friends, she manages to safely land back to Earth before getting brought back to Foresight for testing where she finds out she has the ability to manipulate plasma fusion off her emotions.

With the help of her ex-boyfriend, Professor JB, she's given a suit to help control her powers so she doesn't hurt anyone.

Trivia

 * Her hero name "Summit" stemmed from her suit being called "spatial utility mecha suit" by Reem, the creator.
