8516 The Boss is a LEGO set released in 2000 in the short lived RoboRiders theme. This set is the largest not-combined RoboRider that existed. Boss had two forms of appearance: a flyer who could attach to a motorcycle for in the Dust Area and a large form that could split in three for in the Frost area. It is unknown who Boss was, some say the one who released the virus or the leader of the RoboRiders hence it's name Boss.
