Crystal Boy, alias Crystal Bowie, is a humanoid cyborg with a golden skeleton encased in an indestructible glass body engineered for combat. His right hand mounts a detachable claw that crushes targets, fires lasers, acts as a grappling hook, or launches as a projectile—a tool he wields with sadistic precision, often slitting victims’ throats.

As a top-tier assassin for the Space Pirate Guild led by Lord Salamander, he enforces the Guild’s galactic dominance by eliminating threats, including his rival Cobra. His ruthless ambition centers on proving the Guild’s invincibility, willing to obliterate entire galaxies to cement its supremacy.

Manipulative and cruel, Crystal Boy relishes psychological control, abducting women to brainwash into adoring him before coercing them to murder one another. Despite his cybernetic enhancements, remnants of humanity linger in his taste for luxury—fine wines and gourmet cuisine.

In battle, his glass form deflects energy-based attacks by channeling beams harmlessly through his body. This defense falters under sustained energy reflections, which risk structural damage from overheating. Cobra exploits this flaw, shattering him with a rocket punch after a grueling duel.

Crystal Boy’s schemes target Cobra through calculated manipulation, including exploiting the Royal Sisters—Jane, Catherine, and Dominique—to advance the Guild’s agenda. After cryogenically imprisoning Cobra during Catherine’s rescue, Cobra escapes through Jane’s emotional influence. Their conflict climaxes on the artificial planet Myrus, where Crystal Boy meets his end, breaking his hold on Catherine in his final defeat.
