Meltrox, Trans-Red

Hey there, fellow brick fanatics! If you were building during the late 2000s, you know that Power Miners was an absolute banger of a theme, and the Rock Monsters are the crown jewel of that era's creature designs. Meltrox in Trans-Red is a standout piece because these weren't your traditional minifigures with separate torsos, legs, and arms. Instead, they feature a chunky molded body-and-leg assembly paired with a massive, hinged jaw head piece that gives them incredible shelf presence. Collectors love hunting these down because they bring a totally different silhouette to a display compared to standard humanoid figures.

When it comes to condition, finding a pristine Meltrox can be a fun challenge. Because these figures were built for play—often crashing through rock walls and getting chomped by mining vehicles—the plastic can show minor scuffs, and the painted eyes or teeth on the jaw piece can sometimes exhibit wear. Furthermore, the trans-red plastic has that gorgeous translucent quality that looks phenomenal under display lighting, but it means any deep scratches or internal stress marks from rough handling will really stand out. Snagging one with a tight jaw hinge and unblemished translucent plastic is a major win for any monster collector.

Meltrox in Trans-Red is locked to the 2009 Power Miners wave, making appearances in a couple of memorable sets including the smaller Stone Chopper and the beefier Crystal Sweeper. Because Power Miners has been retired for well over a decade now, finding these creatures complete and in good condition has become increasingly difficult as fans lock them away in nostalgia-driven collections. While not quite as elusive as some of the rarest color variants from the theme, trans-red Rock Monsters still command steady attention whenever they pop up on the secondary market.

You won't find Meltrox in any modern re-releases, meaning the pool of available figures is fixed. As more of these sets get permanently absorbed into private collections, tracking down individual monsters in desirable condition gets trickier by the year.
