The Kree Captain was a member of the Kree Watch in 2091 serving under Kasius in the Lighthouse. He was killed by Alphonso Mackenzie during a confrontation after the S.H.I.E.L.D. agent arrived in the future with his team.
The Kree Captain and his companion went to investigate noise on Level 3 of the Lighthouse and found a group of strangers. After one of them tried to attack his companion, the Captain unleashed his Plasma Gun on the ceiling to knock out the strangers. The Captain then smiled.
After securing the strangers in a cell, the Captain and his companion took two of them to another room for questioning. While the Captain talked about leaving the other three for the floor chief, one came up and demanded to now what they were going to do with her friends. The Captain told her whatever they wanted. When the stranger said they wouldn't make it easy for them, the Captain disagreed, as every Human he encountered always begged before him. He and his comrade then walked off.
The Captain and his comrade walked into the room that the other two were changed in. When the man asked if they spoke English, the Captain answered as if it were obvious they did. The man begged the Captain to let his female companion go, saying she didn't do anything wrong. In response, the Captain punched the man in the stomach, telling him just because they spoke English, didn't mean they wanted to hear it. When the man spoke Spanish, the Captain saw it as a mockery, and continued to punish him. After a while of torture, the Captain suggested to offer the man to Kasius for the pits, as a way for them to be rewarded. The Captain agreed, but proceeded to free the woman's arms, as a substitution for the man's punishment. After a while, the woman who talked to the Captain earlier showed up and and ambushed his companion. After the woman freed the man, he attacked the Captain with his companion's Kree Battle Axe. After a short fight, the man killed the Captain with the Kree axe.
After the Captain and his companion's death, Lighthouse scavenger, Deke Shaw, helped the strangers dispose of their bodies. They took them to the section of the Lighthouse where the Vrellnexians were and let them suck their life, so the Kree would believe they were Humans.
