In training, Kilmoy used logic and strength to pass all courses. He always considered himself the brave one, and he wanted to be the best. Kilmoy ate a lot but managed to stay at ninety-five pounds. He was not a good runner, however, as he hated doing so. Kilmoy also loved demolition, considering himself a pyromaniac. He did not like pyrotechnics though, as he felt they to heavy using the guns. He was put in the 501st legion.
