It's unknown where Dark Energon spiders originate from — possibly formed by Dark Energon, or by manipulating these crystals. But wherever it is, Dark Energon spiders show up. Their only attack is to jump against an enemy. Their body is strange being in the shape of a flattened disc. They have six legs that allow them to rapidly scurry across the ground. Any eyes or mouth that they might have are not visible. They have been actively spawned on multiple occasions. First by Megatron in the Kaon prison, second by the Corrupted Worm, and last by Trypticon himself.
