Lego Rock Raiders (stylized as LEGO Rock Raiders) was a Lego theme focused on mining equipment that released in 1999 and 2000. It was the only underground-based Lego theme before Lego Power Miners. The theme, while short-lived, featured sixteen construction sets and numerous story-related media, including three books and a video game.


Lego Rock Raiders was a short-lived Lego theme that lasted for two years. It was launched in 1999 and discontinued in 2000. Despite this short lifespan, the theme introduced an elaborate storyline that was delivered through video games and comics. The storyline centered on the crew of the spaceship the LMS Explorer and their search for energy crystals. The toy sets were all set on an alien planet. The storyline involved the Rock Raiders' spaceship being sucked through a wormhole into a distant galaxy. The crew must then mine for energy crystals but in the process must also face territorial Rock Monsters. In 2009, the Power Miners theme was launched, which despite not being set in an alien galaxy, had similarities to the Rock Raiders theme by focusing on a group of miners.[2]



There are six characters in the Lego Rock Raiders theme.

Energy crystals

Three of the green energy crystals, the most common variety.

Energy crystals are yellowish-green crystals that contain vast amounts of energy, and are the main sources of power for the Rock Raiders. However, they also serve as the primary food source for the monsters and slugs on Planet U, often resulting in conflicts between them and the Rock Raiders. Energy crystals were introduced in Lego Rock Raiders, and have appeared in several themes since then.

When an energy crystal's energy has been depleted, either by use of a Mining Laser or by Slimy Slugs, it turns either a dark gray or a purple color and has to be recharged at a Recharge Seam.

A rare variety of red energy crystals, five times more powerful than normal green ones, appears in the PlayStation video game, where they serve as bonus pickups to challenge the player for a better score.

Planet U

Planet U's surface

Planet U is the alien planet featured in Rock Raiders. The entire plot takes place on this planet. Planet U is located in another galaxy, outside of the Milky Way. The rock below the planet's surface is abundant with Lego ore and energy crystals. Monsters made out of rock, ice, and lava live in caverns deep underground, feeding on the energy crystals. Other creatures like giant slugs, scorpions, and spiders also make their homes in the tunnels. Runs found in one of the books suggests an intelligent civilization may have once lived on the planet. Planet U has very little oxygen, the Rock Raiders must build Support Stations to purify the air, and make it breathable.


The LMS Explorer being pulled into a wormhole


Rock Raider HQ is made up of a number of buildings. Buildings must be constructed by power paths, which can be used to link buildings together to allow power to flow to them all. Rock Raiders can run much faster on power paths than rubble or cavern floor, and power paths can also be used as dams to temporarily block lava erosion.


Construction sets

The Lego Rock Raiders theme featured fifteen Lego sets in total.[1] Eight main sets were released in 1999, while seven smaller ones were released in 2000. First editions of the 1999 sets included promotional mini comic books. Four of the sets released in 2000 were promotional sets sold by Kabaya Foods Corporation.
