Slizer / Throwbots " You may be looking for Slizer , a minifigure from Space Police . " Slizer , known as Throwbots in the US and Canada , is a subtheme of TECHNIC that launched winter 1999 and continued into 2000 . It features bots that throw . Description . The line debuted a new ball - and - cup system of building that allowed the figures to be articulated in ways not possible with LEGO elements that were extant prior . At launch there were eight elementally themed figures , packaged in special carrying cases that could be worn on a belt . Each Slizer comes with two discs that can be thrown using a special flinger arm . Most of the figures also feature adjustable heads via a gear mechanism . The 2000 wave introduced mutant Slizer , two of which are larger scale figures with dual flinger arms . Development . Christian Faber , who would go on to develop story and art for BIONICLE , also had a hand in the formation of Slizer . His 1995 Cybots concept proposed the ball - and - socket building system that the theme adopted . He also created much of the art , for both the packaging and the faceplates of the models themselves . At one point , selling the models via vending machines was considered . Story . In keeping with the separate theme names between the US / Canada and the rest of the world , the theme has two similar , but distinct , presentations of the story . Slizer . The 1999 general LEGO catalog and the May 1999 issue of LEGO Technic Magazine provide the same account of the Slizer story . Planet Slizer is located 4000 light years from Earth , and is divided into seven elemental zones . A transmission from the planet reads " WE ARE SLIZER . JOIN US . " The bots are evenly divided into two opposing teams - Fire Slizer , Sub Slizer , City Slizer and Ice Slizer are good , and can combine to form the Super Slizer . Judge Slizer , Jungle Slizer , Rock Slizer and Energy Slizer are evil , and can combine to form the Mega Slizer . Each Slizer carries out a mission in his home environment These missions all involve a search for a source of power that will give them an edge in combat . Comics packed with the sets offer small looks into the story . In one , the Slizer participate in a tournament at the Slizer Dome , throwing discs at the energy ring in the center of the arena . Jungle Slizer is the first to land a shot through the ring ' s mouth , and shouts victoriously . In another comic , the good Slizers form the Super Slizer and confront their evil enemies , who in turn form the Mega Slizer . The March / April issue of LEGO World Club Magazine in Germany offers a backstory for the 2000 wave of sets : " There is peace on the Planet Slizer . . . until the day a meteor thunders through the atmosphere and strikes the surface . . . half the planet is crushed into microscopic parts ! " " Many Slizer die in the explosion . From their fragments mutate four new Slizer . They are big , strong , fast and deathly dangerous ! And all four are trying to control Planet Slizer . That ' s why they shoot at everything that moves - including the other Slizer ! " There are four mutant Slizer : Throwbots . In the US , the line is introduced in the January / February issue of MANIA Magazine . The sets are described as robots constructed by aliens in another galaxy . " Light - years " of self - maintenance have led the Throwbots to adapt individually to their respective home planets . All of the Throwbots are described as " Guardians of the Galaxy " ( no , not those ones ) . Each lives on their own homeworld and endures its natural hazards . While the descriptions of most of these worlds match what can be seen on the box art and in the Slizer bios , Turbo ' s world is described as one of rolling hills instead of a techno - city , while Jet ' s is characterized as a " giant gas world " instead of the Slizer Dome . Torch , Scuba , Turbo , and Ski combine to form the super Throwbot Robotops , while Jet , Amazon , Electro , and Granite become UltraRex . In a comic featured on Lunchables boxes , Torch encounters a fire monster too great to be dealt with alone . The LEGO Maniac summons Scuba , Turbo , and Ski , allowing them to form Robotops and fight off the beast . This comic goes back to calling the Throwbots ' home environments " zones , " not " worlds , " in keeping with the Slizer storyline . This change remains with the launch of the next wave of sets in 2000 . The set boxes prominently display the singular , meteor - crushed planet . The January - February 2000 issue of MANIA Magazine provides a short synopsis of the story : " New Years eve a mysterious meteor hits the Throwbots Planet . . . The powerful collision creates a giant crater . And out of the crater , climb four fantastic , new Throwbots . " These new Throwbots include Millenia , who can transform between a large form and a small bike - riding form , and Spark , Flare , and Blaster , who combine to form the super Throwbot Dynamo . Throwbots make their final appearance in MANIA Magazine in the May / June 2000 issue . In a " Battle of the Big Bots , " Millenia and Blaster showdown in an arena to determine who is " the most powerful Throwbot in the universe ! " Discs . The throwing discs used by the Slizer were marketed as collectibles . Six discs existed for each of the 1999 Slizer , labelled from power level 2 to 7 . Each power level featured a different part of the Slizer ' s environment on the disc . Every set contained its own level 2 disc , and the level 3 disc of another Slizer . The rest could be collected from randomly packed 8508 Supplementary Discs sets . The 2000 wave featured seven discs altogether , spread out across the four sets . List of Sets .
