Twn Trwn (pronounced "Tun Truun") was Team Monster's entrant for Series 3 of Robot Wars. Ultimately, one axe blow from Trident immobilised it, knocking it out of the competition. "Twn Trwn" is Welsh for "broken ring". "Twn Trwn sounds like the Thunderbirds' tune - "Twn Trwn!" - certainly needed International Rescue, but it didn't come for Twn Trwn." — Jonathan Pearce
