Starhawk

He is very powerful, able to hold his own against the likes of Thor. Stakar first appeared in "Defenders" vol. 1 #27 (September, 1975) where he was a mysterious alien who joined the Defenders and Guardians against the Badoon. He stayed with the Guardians when the teams parted ways. He has since been retconned to the son of the Earth-691 versions of Quasar and Kismet. He is half-human and half of the same artificially created race as Adam Warlock. He was born on planet Vesper but was abducted shortly after birth. He was raised on planet Arcturus IV by adoptive parents and learned much later they were not his biological parents.

His adoptive parents were mutants who had left Earth and traveled to the stars. They were eliminated by the Reavers of Arcturus, a military force devoted to the cause of eradicating all mutants. To their surprise Stakar had no obvious mutant traits, appearing baseline human. He was adopted by a Reaver, named Ogord. Stakar was an intellectual and pursued studies in science and archaeology. He and his adoptive sister Aleta accidentally revived the dormant Hawk God and were transformed by his powers. The two adoptive siblings have had a complex relationship, ranging from intense rivalry and hatred for each other to at times pursuing romantic relationship with each other.  
 

Powers

Either due to his genetic inheritance of his Divine Powers, Starhawk has a particularly long lifespan. In the Earth-691 reality, he was born in the 21st century and survived to the 31st with little signs of aging. He fires blasts of photonic energy. He can merge with Aleta into a single entity and then create solid constructs of light. His senses are superhuman, primarily his eyesight. He remains sensitive to energy in his environment and can track energy trails across the galaxy.
