Centipeetle's Crew

Centipeetle Mother Big PNG

The Centipeetle's Crew includes two Corrupted Gems that appear in "Monster Reunion". Their bodies and gemstones are the same as the corrupted Centipeetle, implying they are the same Gem type. Interestingly, the bands around the gemstone's of the Centipeetle's crew are not curved, suggesting they did not damage their gemstones being in the safety of the ship.

They did not evacuate Earth when ordered to as they did not want to leave their captain behind, and as a result they also became corrupted. As of now, they live together in the Ancient Gem Colony Ship.
