Theme
Power Miners
Year Released
2009. This figure debuted at the launch of Power Miners, a theme that replaced Mars Mission and brought back the 'underground exploration' concept similar to Rock Raiders.
Rarity
Common. This specific variant was included in multiple entry-level and mid-range sets, making it widely available during its production run.
Head
The head is an integrated part of the upper body mold; it features a hinged jaw that can open to 'eat' crystals. It has small printed eyes (often red or orange) and a craggy stone texture.
Torso
The torso is a unique bulky 'rock' mold in dark stone gray. It features Trans-Neon Green crystalline patterns or 'veins' that represent the monster's energy source. It uses specialized short bulbous arms with standard minifigure clips for hands.
Legs
This figure does not use standard legs; it has two specialized Trans-Neon Green 1x1 round plates with 'toe' protrusions that snap into the bottom of the body mold.
Accessories
Typically paired with Trans-Neon Green crystals (part 30153). While the monster itself is considered the figure, the crystals are its primary accessory and food source in the lore.
Color Scheme
Dark Stone Gray (body) and Trans-Neon Green (internal crystals and feet). This identifies it as the 'Glaciator' type/color variant within the initial 2009 wave.
Printing Details
Printing is minimal, limited to the small eye dots on the upper face. The primary detail comes from the dual-molded plastic effect where the transparent green shows through the gray rock shell.
Variants
There are five primary colors: Glaciator (Green), Firox (Orange), Meltrox (Red), Boulderax (Blue), and Sulfurix (Yellow). There were also larger 'King' versions and later 'Lava' variants in subsequent waves.
Condition Notes
Common wear points include the hinge of the mouth (which can become loose) and the arm sockets which may develop stress marks if the arms are repeatedly removed. The trans-green plastic can show scratches easily.
Estimated Value
Used complete: $3 - $5 USD. New/Mint: $7 - $10 USD. Individual parts like the arms are often lost and cost about $1 each.
Price (New)
N/A - This figure was never sold individually. The cheapest set it appeared in was 8956 Stone Chopper which retailed for $5.99 in 2009.
Compatible Sets
8956 Stone Chopper, 8957 Mine Mech, 8958 Granite Grinder, 8962 Crystal King, 8963 Rock Wrecker, 8707 Boulder Blaster.
Character Background
Rock Monsters are the primary antagonists of the Power Miners. They live deep underground and feed on energy crystals, which the Power Miners are trying to collect. Glaciator is known for being slightly more aggressive or 'cold' in temperament.
Design Notes
The rock monster was a revolutionary design for LEGO as it moved away from the standard minifigure 'block' shape to a more organic, creature-based mold while remaining compatible with the hand-clip system.
Similar Minifigures
Firox (Orange), Meltrox (Red), and the later Wave 3 'Lava' Rock Monsters like Magmox.
Collectibility
High nostalgia value for 'Millennial' and 'Gen Z' collectors who grew up during the 2009-2010 era. However, because they were produced in high volume, the monetary value remains steady and affordable.
History
Power Miners was a major success for LEGO in 2009, revitalizing the 'In-house' non-licensed themes. These rock monsters became iconic for their ability to hold crystals in their mouths.
Interesting Facts
The designers originally considered making the monsters solid colors, but the 'translucent core' design was chosen to make them look like they were glowing from internal energy.
Display Suggestions
Display in a cave-like MOC or within a glass case alongside the different color variants to show the 'spectrum' of the rock monster species. They look best under backlighting to make the trans-green parts pop.
Modification Potential
The arms are frequently swapped with standard minifigure arms for a 'buff' look, and the body mold is popular for MOC builders as decorative 'living' stones in castle or fantasy settings.
Overall Assessment
A quintessential 2000s-era LEGO figure. Its unique mold and interaction with crystals make it a standout design. While it has low monetary value, its 'fun factor' and iconic status in the Power Miners line make it a 9/10 for any theme enthusiast.
