What is "bionoid"

Bionoids are fictional creatures originating in the Spelljammer campaign setting for the Dungeons & Dragons role-playing game.

Bionoids are chitinous, bipedal humanoid insects with a glowing circular gem in the center of their forehead. Though their appearance strikes fear in those who view them, their demeanor belies their looks. They originated as “Living Weapons” during the Unhuman Wars.
