Lego Power Miners


Lego Power Miners was a product range – or "theme" – of the construction toy Lego. It was influenced by the previous 1999 Lego Rock Raiders line. Power Miners is based beneath the surface of the Lego World, wherein a team of 'Power Miners' investigate the cause of a series of severe earthquakes and discover both Rock Monsters and Energy Crystals. The theme was released originally in 2009. It was a theme introduced in 2009 and discontinued in 2010.

Story

The Power Miners are sent underground by the government to investigate a series of earthquakes occurring in the Southwest Region of the U.S that have destroyed several cities on the surface of the Lego World. While underground, they discover the Energy Crystals and the Rock Monsters. They attempt to collect and mine the crystals in order to stop the monsters from consuming them and causing the earthquakes on the surface. However, a bigger threat emerges in the form of The Crystal King, the undisputed ruler of all Rock Monsters underground has awoken from his years of sleep.
In January 2010, Power Miners were brought back to life in the new sub-theme Power Miners: Core of the Underworld. The plot, based on the November 2009 comic, shows the Power Miners fighting the Crystal King with the Titanuim Command Rig, but they accidentally break through the cave floor and fall into the inner core of the earth, where they also find the Lava Monsters: Firax, Combustix, Infernox, and Eruptorr. To keep themselves from boiling from the hot climate, Brains creates heat-protection silver suits, and designs a large base known as the set "Lavatraz." Their new vehicles involve usually water cannons, to put out the lava and Lava Monsters. Therefore, the color scheme changed from lime green and orange to lime green, grey and blue. The Energy Crystals also change into Lava Crystals, which is what the Lava Monsters eat.

Characters

Miners

2009

Doc is the leader of the group, and is determined to discover what hides underground. He has also been on other adventures. Brains is the team scientist. He is fascinated by the rock monsters and would like to capture a Rock Monster to take to the surface for study. Rex is the engineer who builds the Power Miners vehicles, while Duke is a veteran miner who has dug for precious minerals around the world. The other miners are Duke's assistant miners and the engineer. While underground, they discover strange energy crystals and the Rock Monsters, the source of the earthquakes. So far, they have a total of 12 vehicles to fight the Rock Monsters with. They have a large base and a mobile drilling rig Most of the vehicles are equipped with giant drills and elaborate gear mechanisms.

2010

In 2010, the miners were fighting the crystal King with the Titanium Command Rig when the expedition opened an entrance into the inner core of the Earth. Brains then created new heat-protection silver suits to protect themselves from boiling. Rex also designed three new vehicles all equipped with utensils to stop the Lava Monsters. A new base was designed by Brains and built by Rex called "Lavatraz," a portmanteau on the words lava and Alcatraz, a famous prison located near San Francisco. Note: The 2009 Power Miners vehicles were built mostly for mining, while the 2010 vehicles are built for capturing lava monsters.
Rex is seen wearing the new, silver, heat-resistant armor of the 2010 line-up of sets. Before Doc called him, he was working on a giant geo-thermal power station. This could have been adapted to the Underground Mining Station. He designed and helped build every vehicle, and in 2010 he teamed together with Brains to design and build their new vehicles and base. He also specially designed and built the Fire Blaster himself.
Appearances:
– Claw Digger, Crystal Crawler, Rock Wrecker, Underground Mining Station, Rubble Rescue Rover, Fire Blaster
Brains is a famous scientist of the Power Miners. He is the one who started the whole operation and would love to bring a Rock Monster to the surface to be studied. He got his nickname, "Brains," from Rex when they first met. He and Doc, his colleague, who asked him to lead the operation. He designed the Mine Mech and also built it, the Crystal Sweeper, which he did not build, along with the Titanium Command Rig. Later in 2010, he specifically teamed with Rex and the engineer to create the four vehicles and base. It is unknown why he wears a monocle over his left eye. When his mission with the Power Miners was completed, he joined the Atlantis Salvage Crew.
Appearances:
– Mine Mech, Cave Cutter, Crystal Sweeper, Crystal Crawler, Titanium Command Rig, Rock Watchman, Blast Roller, Claw Catcher, Deep Sea Raider
Duke is a veteran miner, although he has never seen anything like the Rock Monsters before. So far he has appeared in most sets from the Power Miners line. In 2010, Duke is seen sporting the new silver, heat-resistant armor. He has dug for gold, diamonds and survived cave-ins and floods. He sometimes is not sure if he even believes in the Rock Monsters and crystals. He was asked to help him by his friend Doc, because of his reputation. He helped build the Thunder Driller, Titanium Command Rig, and the Cave Crusher. Later, in 2010, he helped build Lavatraz.
Appearances:
– Thunder Driller, Aero Shredder, Titanium Command Rig, Rock Watchman, Blast Roller, Lavatraz, Cave Crusher
Doc is the leader of the Power Miners team. He has been on many adventures around the world. He was asked to lead the operation by his colleague, Brains.

Rock Monsters

The Rock Monsters are the enemies of the miners. They appear in all the sets from the Power Miners series. They are made of different colored rock and crystals. There are five different kinds of Rock Monster. The rock monsters are Meltrox, Boulderax, Glaciator, Sulfurix, Firox, Geolix, Tremorox and RockRage. They are shown to have some primitive technology, like monster launchers. The Rock Monsters eat crystals, which give them power. If a rock monster eats a different colored crystal to what it is it will burp and break wind.
In 2010, the Power Miners found out more about the Rock Monsters. The rock monsters are creatures that formed in the core and crust of the earth over thousands of years. They then traveled into the mantle of the lego world. The first of the monsters was the Sulfurix, who had begun gathering the energy crystals to gain power and tunnel to the world above. Brains also found out that the monsters were made of Rock and Kinetic energy trapped in rock form. The crystals gave them the power to grow in size, and release the energy from the crystals in any way they wanted to, explaining their powers. Some Sulfurix grew from crystals into the Geolix, also making the powers more severe. Finally, after thousands of years, a Geolix had turned into RockRage, the massive Crystal King. He then created the other four types of monsters. This is also the theory for the Tremerox. Soon, when the Rock Monsters planned to tunnel to the top of the surface, they would take it over using the power of the crystals.
Meltrox is a red species of Rock Monster from the Power Miners line. The Meltroxes are angry, destructive, and full of rage when they're in a good mood, when they are in a bad mood, they are much worse, which is why part of his name is melt, as in destroy. He is plainly mad at everything all the time and has problems with his temper. He is a red monster and eats red Energy Crystals. He is always the first to fight, even if there are crystals for the taking. Meltrox is one of the four types of rock monsters created by the Crystal King. Once he eats a red energy crystal, he is shown to have a surge of anger that he uses to destroy certain things. He has two cousins, the Tremorox, who are large versions of Meltrox, and the Infernox, who are versions of Meltrox heated up badly. He often attacks with Glaciator.
Appearances: – Stone Chopper, Cave Cutter, Crystal Sweeper, Crystal Crawler
The Boulderaxes are strong, slow, but not so smart. They are green. Once they start attacking miners, they forget about the crystals. Glaciators get them to do their dirty work for them. The Boulderax are as dumb as a bag of rocks, and will fight the Thunder Driller just for the fun of it. He is one of the least common rock monsters. The Boulderax are one of the four types of monsters created by the Crystal King. Once he eats a green energy crystal, he has super-strength. He has no cousins and is exclusive to the Mine Mech set.
Appearances: – Mine Mech, Cave Cutter

The Glaciators are nasty, and evil. These Rock Monsters are blue and are feared by the other Rock Monsters. They get Boulderax to attack the miners while they feast on crystals. If there is trouble underground, you can be sure Glaciator is behind it somehow! He is the most common rock monster, being in 9 sets. The Glaciator are one of the four types of monsters created by the Crystal King. Once eaten a blue energy crystal, he can freeze water, rock and even power miner vehicles.
Appearances: – Granite Grinder, Aero Shredder, Cargo Crusher, Crystal Sweeper, Crystal Crawler, Boulder Blaster, Titanium Command Rig, Rock Watchman, Blast Roller
The Sulfurixes are clever and sly. They appear where you least expect them. They can make tunnels by melting through rock and can eat a load of crystals very quickly. He is the rock monster used in all promo sets including rock monsters. Once he eats a yellow energy crystal, he is able to tunnel through solid rock, and is probably the one who made the caves and tunnels in the first place. The Sulfurix was the first rock monsters to reach the Lego world. One ate the crystals and grew into the Geolix. Later, a Geolix grew into the Crystal King. The Sulfurix have three cousins, Geolix, a large version of Sulfurix, RockRage, the Crystal King, and Combustix, Sulfurixes that are heated up badly.
Appearances: – Monster Launcher, Claw Digger, Crystal Crawler
To date, Firox have only appeared in one set. Firox are sneaky and curious by nature, and fastest of all the rock monsters. Rex hates Firox the most, because they ruin all the machines he made. He enjoys stealing the Power Miners tools, playing tricks and messing up machines. He is one of the four rock monsters created by the Crystal King. Once he eats an orange crystal, he has a surge of super speed. He has two cousins: Firax, which are the Firox heated up badly, and Eruptorr, the larger version of the Firax.
Appearances: – Thunder Driller, Aero Shredder
Geolix is a Rock Monster from the 2009 Power Miners line. He is a large rock monster, and is similar in appearance to Sulfurix and the Crystal King. He can hold crystals on his back while he fights. Large monsters can launch rocks and small rock monsters with a lever on their backs. He is cunning and crystal-hungry, and is shown to be a bully and bosses around the Sulfurix. He constantly is making up games to throw around the small monsters as well. He has incredible strength and uncanny aim, and is a threat to every power miner vehicle. He has three cousins, the Sulfurix, the smaller version of Geolix, RockRage, a king version of the sulfurix and Geolix, and the Combustix, who are the Sulfurix heated up badly.
Appearances: – Rock Wrecker, Underground Mining Station, Rubble Rescue Rover
Tremorox is a Rock Monster from the Power Miners line. He is an enlarged Meltrox. The Meltroxes are angry, destructive, and full of rage. They always want to be the first to fight even when they could be chomping down on crystals. Tremorox can also launch rocks with a lever on his back just like Geolix. He is the angry, bigger and stronger leader of the Meltrox, and hates anything and anyone. The only thing he enjoys is smashing the power miner's vehicles. He has two cousins, the Meltrox, who are the smaller versions of the Tremerox, and the Infernox, who are versions of the Meltrox heated up badly.
Appearances: – Cave Crusher, Titanium Command Rig, Rock Watchman, Blast Roller
RockRage the Crystal King is thousands of years old and glowing from crystals he's devoured over centuries. He is the ultimate, undisputed ruler of all the monsters underground. His strength is unrivaled by any known monster, and grows stronger as he grows older. He may eat any type of crystal and can access any known power once he does. He has huge, pointy spikes, crystal teeth, and mysterious crystal armor plates. Soon, as every king monster does, he had to sleep for years to regain his strength. If a rock monster fails to give him enough crystals, he will eat the monster itself! He was awoken by the Titanium Command Rig, but it just so happened he regained enough power at the same time. He is cousins with all rock and lava monsters, but rules over only the rock monsters. He plans to "drill" to the surface world and conquer it as his own, and has the monsters do his bidding. He and the other monsters loathe the lava monsters and plan to travel to the earth before them. He is defeated when falls in the lava monsters territory
Appearances: – Crystal King

Lava/Magma Monsters

The lava monsters are the new antagonists of the 2010 Power Miners line. They have to be fought with water instead of dynamite and other tools and live in the molten Lava chambers of the Earth which are deeper than the rock monsters.
The lava monsters are really rock monsters that were heated up badly when the monster race was beginning. A Sulfurix was heated in the magma chambers to create Combustix. Later, a Firax was created when a Firox fell in boiling lava. The same happened to Meltrox to create Infernox. The Lava Monsters then ate lava crystals that were made of lava and kinetic energy trapped in igneous rock formation. The monsters were made of the same material. Just like their cousins, the monsters release a form of energy once eating a crystal, in ways involving lava and volcanic eruption. A Firax once later grew in size to the powerful Eruptorr, who ruled the monsters. The Lava Monsters hate their Rock Monster cousins and wish to take over the LEGO world before them.
The Miners built Lavatraz, a large base designed to hold the monsters until destruction, along with water gun protection. Brains read more about the monsters and crystals and discovered the only way to defeat them was to put them out with water. Four vehicles were then created to capture the Lava Monsters and crystals and bring them back to base where they'd be destroyed. The monsters were then imprisoned in Lavatraz, where a crane would pick up a monster and dump them in a large tank filled with liquid nitrogen. This would completely destroy both for good.
Combustix is a yellow Lava Monster. He is the first lava monster, and is led by the lava monster leader, Eruptorr, along with the Firax and Infernox. He is similar in color to Sulfurix, though his carapace is a slightly darker, drabber yellow. The crystal he holds, however, is the same color as Sulfurix's. It is likely that Combustix monsters are heated Sulfurix, because Firax monsters might be super-heated Firox monsters. Brains is hardly sure of what the Combustix are made of, and all he knows is that it is hot and goopy. When the Combustix eats a yellow lava crystal, he leaves sizzling puddles of molten goo that burns everything in its path, and is also the reason why he doesn't stay in one place. He has three cousins, the Sulfurix, which is a rock version of him, the Geolix, a large version of the Sulfurix, and RockRage, a king Sulfurix.
Appearances: – Fire Blaster
A Firax is a Lava Monster that appears in the 2010 Power Miners line. Firax has a trans-orange carapace with black arms. Firax is the same orange color as Firox. Firax is included in two sets, as shown below. He seems to have scratches all over his fiery body. Also, Firax is said to be a Firox on fire. What happens when you put a Firox in super heat? You get an even trickier Firax to deal with!. This explains that Lava Monsters might be Rock Monsters somehow modified by high levels of volcanic heat to create Lava Monsters. Apparently, Firax likes to trap Power Miners and take their vehicles for joyrides- melting the seats in the process! They're mischievous like they're Firox cousins, and love trapping the power miners. Once they eat orange lava crystals, he can create a flood of lava in the chambers, much to the pleasure of the Infernox. He has a cousin and a brother, the Firox, a rock version of the Firax, and the Eruptorr, a larger version of the Firax.
Appearances: – Magma Mech, Lavatraz
Infernox is a Lava Monster in the new 2010 Power Miners series. His carapace is the same trans-red color as Meltrox. Because Firax monsters are described as super-heated Firox, Infernox is likely a super-heated Meltrox. The Infernox are wild and crazed because their brain is constantly boiling. They are constantly running, bouncing, whirling, crashing and splashing in lava streams and pools of the core of the earth. They're almost impossible for the power miners to catch, and even harder to hold once they do. They admire the Firax work, especially when they create more lava pools to splash in! They have two cousins, the Meltrox, a rock version of the Infernox, and the Tremorox, the larger version of the Meltrox. Once one eats a red lava crystal, he leaves a huge fire behind him, hence the name Inferno-x.
Appearances: – Claw Catcher
Eruptorr is a throwing Lava Monster in the 2010 Power Miners line. He is similar in appearance to the 2009 large throwing Rock Monsters, but is a Lava Monster. He has transparent orange legs and a black body. He is a larger version of Firax, and has flames all over his back. He is the biggest, strongest and loudest of the lava monsters, and is a primal volcanic force that rules the Earth's core with a fiery fist. He refuses to stop until he has personally driven the power miners out of the core. Once he eats an orange lava crystal, he can throw a limited amount of lava balls, and in rare cases, if he eats a lot of crystals, he can cause small volcanic eruptions. He has one cousin and one brother, the Firox, a rock version of the Firax, and the Firax, the smaller versions of Eruptorr.
Appearances: – Lavatraz

Similarities/Differences between Power Miners and Rock Raiders

One obvious element that was already present in the Rock Raiders theme was the occurrence of Rock Monsters and Energy Crystals in the story. However, in the Lego Power Miners, the Rock/Lava Monsters play a bigger role and are included in every set and each Rock/Lava Monster are all named characters with different personalities and traits.
The Lego Power Miners and Lego Rock Raiders theme both have settings that take place underground and both themes have each team search for crystals, whilst trying to prevent the Rock/Lava Monsters from eating them. However the difference is while the crystals in Lego Rock Raiders were Energy Crystals with massive power in them, the Lego Power Miners crystals seem to be kinetic energy based instead. While Lego Power Miners collect their crystals for research purposes, the Rock Raiders collect them as fuel for their ship. Another difference between the themes is that the Crystals eaten by Rock Monsters in Power Miners make them release the kinetic energy, causing massive rumbles when underneath the surface.
The Power Miners are dressed in blue/gray clothing and their vehicles are green/orange and very large, similar to real-world mining equipment – a difference between this theme and Rock Raiders, which is more futuristic with more compact vehicles and grungier colors. Power Miners also implemented several features that only appeared in the planning stage of Rock Raiders, such as the concept of a mobile base and a common uniform for the miner minifigures.

Features

The rock monsters have a flip top head, revealing the crystal stored inside. Keyring variants of rock monsters sent with monthly Lego magazine subscriptions have a fixed metal screw eye through the top of the head, and do not open. The screw eye can not be removed. It rotates, but does not withdraw from the plastic. Although there is a method of removing the metal screw.
Large monsters, such as Geolix, have a lever on their back that, when pressed/pushed, swings the left arm of the monster, which allows it to throw either rocks, crystals, or smaller monsters. Geolix and Tremorox all have studs on their backs for holding onto crystals. Unlike their smaller cousins, Large Rock Monsters cannot open their mouths. The largest of all monsters is the Crystal King, who is the boss of all monsters. He features a huge opening jaw, moveable limbs on ball joints, and fingers that can grab objects. He was last shown battling the power miners' titanium command rig when some of the power miners fell into the core of the earth, home of the lava monsters.
