Stinger, an aged figure with weathered features, possesses scaly light-green skin and unkempt medium-length green hair. His layered attire includes a tan overcoat, a blue vest beneath, a green shirt, and a crimson tie. When transformed into his Invader state, he serves as the armored shell and rear segment of a colossal amalgamated beast, sporting five spindly legs flanking each side, a serpentine neck supporting a horned head, and a whip-like tail.

A former physicist renowned for his expertise in Getter Rays, Stinger collaborated closely with Dr. Saotome until he and associate Cowen succumbed to an Invader infection that mutated them into thralls under extraterrestrial control. Tasked as vanguards for the Invader invasion, they commanded the fearsome Metal Beast Dragon. Confronted by the Getter Team’s Shin Getter Robo, their mechanized beast was nearly obliterated by the Stoner Sunshine assault. Fleeing to Jupiter, the pair plotted to convert the planet’s Getter Core into a stellar energy source. Their final gambit saw them fused into a towering bio-mechanical horror to eradicate the Getter Team, only to meet annihilation via Shin Getter 1’s Final Tomahawk strike.

Stinger’s tactical prowess extended to piloting the Metal Beast Liger through neural symbiosis with his Invader parasites. His monstrous form also channeled energy as a living transmission array.

His visual aesthetic echoes the sinister motifs of *Majuu Sensen*’s Dr. Barbia.
