Great Thunderbug

The Great Thunderbugs are small wisping globes of light which seem to be swarming Thunderbugs. They are about the size of a Vespoid and have a tendency to wisp around the area rather than attack trespassers. They are also known to change into two different colors: blue and white. When in its normal and docile state, they are blue, but when attempting to attack, the blue hue becomes a fierce, glowing white, at which time they will harm you with strong electrical currents. They are naturally found in the Tower, but eye-witness reports claim that they can be internal hosts of elder dragons.

They are hatched in Yamatsukamis, which acts as a safe barrier for Great Thunderbugs as they mature.
