Bullet Bug

Bullet Bug is a special insect found both within YGGDRASIL and the New World.

Appearance
A three centimeter-long insect that gleamed with a steely radiance and the front of its V-shaped bodies is sharp, bearing a strong resemblance to a rifle bullet.

Abilities
This bug could punch holes in steel, and even a large tree would be riddled full of holes. When used in swarms as shown by Entoma, they can become akin to a Gatling gun.

Trivia

 * The bullet bugs gather in groups to Entoma's left wrist before propelling themselves at a target on the command of the summoner.
