Early Life

Roberto da Costa is the son of Brazilian millionaire Emmanuel da Costa and his American wife Nina, an archaeologist. Roberto first manifested his superhuman mutant powers when, at the age of fourteen, he was playing in a championship soccer match for his school team in Rio de Janeiro. Motivated by racial hatred, a boy named Keller and another member of the opposing team knocked da Costa to the ground. The hot-tempered da Costa retaliated by tackling Keller, who began brutally beating him. It was then that, without being aware of what was happening to him, da Costa first manifested his superhuman strength. His body and clothing temporarily turned black in the process, and he inadvertently hurled Keller away from him. Confused and frightened, da Costa sought help, but both the other players and most of the spectators panicked and fled. However, his girlfriend, Juliana Sandoval, who had been watching the game along with Emmanuel, stood by Roberto in his time of need.

Days of Future Past

During the war with the Sentinels, Sunspot joined the resistance group known as the Free Mutants.

Powers and Abilities


Solar Radiation Absorption: He can absorb solar energy and can utilize it for physical strength. The cells of a normal human body convert energy from foodstuffs into a form of energy usable by the body. This energy is stored through converting molecules of adenosine diphosphate (ADP) in the cells into adenosine triphosphate (ATP); the energy is released when necessary by breaking a chemical bond in the ATP molecules, converting them back to ADP. Apparently Sunspot can store solar-derived energy in his cells through the same, or a similar method, and release it when necessary to enhance his physical strength. His body is cloaked in darkness because he drains all the ambient light from his skin.

Solar Re-channeling: He possess the ability to re-channel the solar energy which his body absorbs, by which he takes the solar energy and uses it for a variety of related purposes:

  • Flight: He possess the ability to fly by propelling himself through the air, by force of will, by generating thermal updrafts. Bobby has also refined this ability to be able to hover in the air without leaving a heat trail, and can reach speeds of up to 150 mph maximum without over exerting himself.
  • Enhanced Strength: When Sunspots cells are powered by solar energy he has the superhuman ability to augment his physical strength. The original limits of his strength was that of 2 tons. Since then however his strength has increased to 50 tons.
  • Limited Durability: Sunspot is one of the interesting powerhouses of the Marvel Universe due to the fact that he is one of the only that does not have a heightened sense of invulnerability. Although Sunspot has not been seen able to deflect bullets his limited durability does provide his body the needed protection to be able to lift the massive weight that his super strength allows him to. Recently, Sunspot has been seen to withstand the impact of a eighteen-wheeler moving at 100 mph and remain nearly unharmed.
  • Thermokinesis: Ability to project heat in intense waves when he absorbs and re-channels solar energy from any part of his body to raise the temperature. Roberto can also absorb heat into his body to lower the temperature in his immediate area. He can also project and absorb heat directly into/from people, causing intense discomfort at their fluctuating body temperatures.
  • Thermokinetic Concussive/Energy Blasts: Sunspot has the ability to fire blasts of heat and concussive force.
  • Dark Solar Plasma Blasts: He has the ability to project concussive dark plasma energy blasts from his hands, with about 20 tons of force behind them at their most powerful.
  • Fire and Heat Immunity: As is the norm with most pyrokinetics, Sunspot is immune to all forms of heat and fire as they simply add to his abilities and his mutant metabolism is able to simply convert these two forms and augment his abilities. This includes heat powers that are directed at him as well as heat that is present because of weather conditions. Sunspot has also been seen with the ability to absorb the energy that fire gives off and has remained unharmed while walking through it.


Combat (Unarmed/Armed): Sunspot has been trained by mutants in combat.

Athlete: Roberto is a very skilled soccer player, and used to play for his high school soccer team.

Multilingual: Roberto speaks English, Spanish, and is fluent in Portuguese.
