As the Sentinels are dispatched to find and kill mutants living underground, Iceman, Colossus, Sunspot, Blink and Warpath hold them off while Shadowcat and Bishop attempt to travel back a few days before the attack. Before the time-travel occurs, Sunspot is killed by a Sentinel who had acquired Iceman's freezing abilities.
With the timeline altered, Sunspot retreats with the group to a monastery in China where they meet with the X-Men and send Wolverine's consciousness back in time to 1973 and alter the timeline to prevent the current war against Mutants. While Shadowcat performs the process, Sunspot and the group guard the monastery from Sentinels to give Wolverine enough time in the past to complete his mission. Sunspot is later impaled and killed by a Sentinel using the powers of Lady Deathstrike. As the Sentinels entered the monastery and prepared to kill the remaining Mutants present, the time travel process was completed and the timeline was altered, erasing the future war.
Due to Wolverine traveling back in time to January 1973, and preventing Bolivar Trask from being assassinated by Mystique, and changing the significant events after that point, the Sentinel Wars never took place. Thus the Free Mutants were never formed, and its members never killed in the future war.
Solar Radiation Absorption - Sunspot absorbs 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. Apparently, Sunspot can store solar-derived energy in his cells through the same or a similar method, and release it whenever necessary.
Solar Form -
Sunspot in its solar form
When Sunspot absorbs enough solar energy, he can be transformed into a humanoid sun, giving him great power.
Solar Beam Emission - Sunspot is able to generate bursts of solar energy from his arms and chest.
Flight - Sunspot is able to fly in his Solar Form.
Superhuman Strength - When Sunspots cells are powered by solar energy, he is able to augment his physical strength, allowing him to fight off Sentinels for a short time.
Superhuman Durability - Sunspot's transformation increases his physical durability, allowing him to withstand fighting Sentinels for a short time.
In the film X-Men: Days of Future Past, Sunspot is a Brazilian mutant played by Adan Canto who is Caucasian Mexican. But in The New Mutants film, Sunspot is played by Henry Zaga, who is Brazilian.
