About LEGO Technic Slizer

LEGO Slizer, which was also known as Throwbots in the US and Canada, was a subtheme of TECHNIC that launched in 1999 and replaced by Robo Riders in 2000. The Slizer sets came with two discs that can be thrown using a special flinger arm.
1999 LEGO Sets
1999 was a landmark year with the launch of LEGO Star Wars, the company’s first licensed theme, debuting alongside The Phantom Menace. This partnership with Lucasfilm transformed LEGO’s strategy and ushered in the era of licensed themes. New original lines included Rock Raiders, Slizers (Throwbots), and Adventurers: Jungle, while LEGO Education was formally established from LEGO Dacta. Several older themes—Cyberslam, TechPlay, UFO, Insectoids, Znap, and Model Team—were retired, marking a clear generational shift toward modern play concepts and digital engagement.
