Lego Rock Raiders was a Lego theme started 1999, and was discontinued in 2000. Rock Raiders was the only theme in the Lego Underground series before Power Miners. The theme, while short-lived, featured sixteen sets and was backed-up by numerous story-related media, including several comic books and video games.
The Rock Raiders HQ, also called the Ore Processing Plant, is the largest set. Included with this set is a Mining Laser, which requires two AAA batteries. The set includes one miner minifig, one Docs minifig, one Jet minifig, one Sparks minifig, two pieces of Lego Ore, two Energy Crystals, one small Transport Truck, one unnamed flying vehicle (similar to Hover Scout in PC game)and one rock monster.
The Rapid Rider comic starts with Bandit finding a piece of Lego Ore, he begins to bring it to Rock Raiders HQ with the Rapid Rider. As he is cruising down he meets a dead end and takes apart the Rapid Rider, he brings its parts over to the other side to rebuild it and then continues cruising. Along the way, he falls asleep and his vehicle cruises past a huge Energy Crystal cavern, and some Rock Monsters making statues. He then approaches a waterfall and falls down the edge, bumping all over and finally back into the water which wakes him up, he then arrives at Rock Raiders HQ.
The Rock Raiders HQ comic starts with everything going smoothly at the HQ, the Energy Crystals are processed in the Power Station and the Lego Ore is sent to be taken away via the Rapid Rider, miner manages to dump the Ore on Docs. Jet is operating the Upgrade Station when a irritating fly bothers her, she tries to whack it away but accidentally knocks the controls, the Ore being carried knocks Sparks off his flying vehicle and lands in the Power Station and gets a black face from the Power Station's beam. The Ore then knocks the Ore Refinery apart and Axle is dumped onto a Small Transport Truck, the Ore falls off the crane and smashes onto the Power Station laser which turns around and fires at one of the Upgrade Station supports. The Upgrade Station falls apart and Jet jumps out, but she is rescued by a Loader Dozer as the whole base falls apart. The crew is dismayed but starts to rebuild the base. The fly is unharmed and starts to irritate Bandit.
