Arena Killer was a competitor in the first series of Dutch Robot Wars. It fought through to the second round, where it fell to eventual runners-up Lizzard. In addition, Arena Killer fought in German Robot Wars under the name Absolut Krankhaft, German for "Absolutely Nauseating", because there were not enough native German competitors. Because the letters were welded on the robot, the team needed a name for the German Series that used the same letters. It was chosen by Werner Hess who was the team's speaker in German interviews. Absolut Krankhaft fell in the first round against eventual winner and runner-up Black Hole and Tsunami.
