Lance Metcalf
From Tardis Wiki, the free Doctor Who reference
Lance Metcalf was one of the first kids to go missing while playing Combat 3000, a laser tag game.
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, Simon Metcalf, 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. Luke dispensed with the nickname when he realised it was insensitive. (TV: Warriors of Kudlak)
