Katokk Alzamille

A long serving member of the United Nations Earth military, he stayed on and continued his service with the New United Nations Earth military. Working his way up from the enlisted ranks during the 7th Space War, he served as one of the ground troops. His actions on and off the battlefield have made him unpopular with officers, his offenses including shooting one of his own commanding officers.

Using himself as a human shield, Katokk protects Garrod and Tiffa till Jamil can take out the soldiers with his own machine gun. Mortally wounded he lays dying in Garrod's arms, telling Jamil the truth, that his family was killed by the United Nations Earth by a poison gas attack, but he found it easier to blame Jamil and Newtypes instead of the government in which he served. Before he dies in the arms of the young boy, he tells him not to make the same mistakes that the past generation did.
