Creature 666, like most Bydo, is a biomechanical creature. It's a large creature with a spiky shell, capable of firing green laser beams at targets.
Creature 666 flies in straight patterns, firing beams ahead of itself. Though the creature is easy enough to dodge, R-craft pilots will encounter this Bydo in an area with deadly electrical orbs that run on a track; these orbs are invulnerable and must be carefully navigated, even as the battlefield rotates. The creature speeds up as it takes damage.
Creature 666 is the second boss of the Fire Cask Factory.
- The number 666 is a number often associated with the Devil.
