Lance Metcalf

From Tardis Wiki, the free Doctor Who reference

Lance Metcalf was the son of Simon and Carrie Metcalf and a student at Park Vale Comprehensive School.

An avid gamer who lived for video games, in the 2000s, Lance had been taken prisoner by Uvlavad Kudlak during the laser tag simulation game Combat 3000 to fight in a war for him. When Kudlak found out the war was over, he returned all the children that hadn't already left his spaceship to Earth, including Lance.

Lance's father, Simon, 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)
