Biography
Lance had actually been taken prisoner by Uvlavad Kudlak to fight in a war for him. He befriended Clyde Langer and Luke Smith and they confronted Uvlavad. When he found out the war was over, Uvlavad returned all the children he had taken.
Lance's father was a British Army soldier who had been killed in Iraq. Luke Smith, not knowing this, had coined the nickname "the Corporal" (as in 'Lance-Corporal') for him at school. (SJA: Warriors of Kudlak)
