Former Guardian known as Starlight
Marissa was one of the younger Guardians and spent time in Ang’s Youngbloods as well. Flight, bolts of energy, light based shielding were some of her abilities. She always seemed to be a hero out of responsibility more than any sort of enjoyment of her powers or even the benefits of being a hero. She had a secret identity, although it was generally known to the Guardians
Since Destruction Day, she has generally thrived in Refuge Point, being one of the more well like people across groups. In some ways, her agreement to leave Refuge Point may have one of the more surprising choices, since she could have kept living her life there without any interruption.
