Biography
In truth, Lance had been taken prisoner by Uvlavad Kudlak so that he could fight in a war for him. He befreinded Clyde Langer and Luke Smith and they managed to confront Uvlavad. It was revealed the war was over and so Uvlavad returned all the children he had taken.
His 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)
