Alexander Summers (Earth-21399)

Early Life
Alexander Summers is the son of former Air Force pilot and Gulf War veteran Christopher "Corsair" Summers, who lived on a small ranch outside of Anchorage. The Summers family lived a normal life until one fateful day when they were flying home from a family vacation in Christopher's private jet. At some point during the return flight, their jet suffered catastrophic engine damage, and Scott was forced to jump alongside his older brother, Scott.

Neither of their parents' bodies were recovered from the wreckage. Scott suffered a minor brain injury in the fall due to their overburdened parachute sustaining damage, while Alex was relatively unharmed.

Scott and Alex were subsequently sent off to an orphanage. During their stay, Scott started suffering severe headaches and eye strain, which made him a target for bullying by one of the other boys at the orphanage, and Alex got injured more than once while trying to protect Scott. This continued until the day Scott's mutation finally manifested and he tore the orphanage apart with his optic blasts. The administrator attempted to contact the government and have Scott taken away from Alex, though both were picked up by Charles Xavier and Henry McCoy in their Worthington & Sons aircraft before this could happen.

The Xavier Institute
Scott's mutant manifest was the catalyst for the mutant panics in the United States, since it occurred publicly. Alex agreed to stay at the Xavier Institute under the alias "Lucas Redding". Scott stayed for the sake of keeping Alex safe.

Alex's mutation later manifested inside the Institute during a bit of roughhousing with Scott in the gymnasium. The whole room was trashed, though neither brother was harmed. When the boys went to train with their powers, Alex found that he could not control his plasma blasts no matter how hard he tried, even though he had no biological issues like Scott did. In the wake of this, Hank built a containment device to control Alex's blasts.
