101 is a low tracked robot armed with a small spike weapon. It was notable for being named 101 as it was rumoured that the whole robot only cost £1.01 to build. It actually cost slightly more than this at £5, and the name actually came from the length (101cm) and a team member's love of 101 Dalmatians, but was still remarkably inexpensive. 101 was fairly successful in Robot Wars, reaching the second round of the Semi-Finals of Series 3, reaching the heat final of Series 4, and winning the Series 4 Tag-Team Terror Tournament, alongside King B3, before suffering a disappointing first round exit in the Fifth Wars against Fluffy. Because of its tracks, 101 could run inverted when flipped, and this ability was maintained in-game.
