Now OWI brings the Sumo tradition to your home. The super warrior SUMO ROBOT can be controlled to assail and overpower its opponent or retreat to prepare for battle. An infrared sensor beam is emitted when detecting an opponent. Upon detection, it instructs the brain of SUMO to "charge", thereby creating a bonafide wrestling match! You can be the referee (gyoji) and decide who the grand champion (yokozuna) will be. Buy two and let the SUMO ROBOT (wrestling) match begin!
