Powers: can absorb solar energy and convert it for use as physical strength
Roberto is an insecure, hot-tempered Brazilian boy. He has been known to fly off the handle over the most minor incidents, and often gets into fights with his fellow teammates (especially Berzerker.) He loves the fact that, with his power, he's stronger than everyone else on the team - at least during the sunlight hours, when he's able to draw solar energy from the sun. It's clear emphasis on his super-strength is a result of feeling inferior in other areas of his life.
