Colt

Colt (コルト, Koruto?) is an chimera ant with angel-like wings on his back and bird-like claws for feet. He was among the first chimera ants to be born by the Queen following her change to an all-human diet. Colt is first seen in the manga leading his squad on a food-gathering attack on a human farming settlement. Throughout his appearances, Colt projects a very strict and formal attitude. Colt is seen pressuring other squadron leaders to become better organized, and also seen monitoring the work of the others. He is extremely devoted both to the Queen and his work, and was the only squadron leader that always gave all the humans he killed to the Queen as food. When the Queen was grievously injured as a result of the King's birth, Colt was the ant that decided to surrender contacted the Hunters in order to secure medical attention for her, and even offered his own organs to save her life.

Colt's loyalty and desire to protect is a trait inherited from the first human eaten by the Queen, a young boy trying to protect his sister Reina. Colt was partly born of the boy's genetic material, and had residual memories of Reina, even mentioning her name without realizing it. After the Queen's death he cursed his inability to protect her and Reina, but soon noticed a tiny infant, no larger than a finger, among the Queen's remains and vowed to protect and raise it. Following this emotional scene, a tearful Morel declared he himself would protect Colt and his ward from harm if they could learn not to eat humans.
