Description
Captain Gedorian, known as the Fanged Captain, is a major antagonist from the Kamen Rider series Kamen Rider BLACK RX, serving as one of the four key commanders within the Crisis Empire's invasion force. He holds the position of leader over the Alien Lifeforms Unit, also known as the Strange Demon Soldiers' Alien Unit, reporting directly to General Jark, the commander of Earth's invasion operations.

Gedorian is a small, unusual-looking creature whose physical appearance sets him apart from his fellow officers. His most defining behavioral trait is his constant, restless motion, as he is perpetually jumping around and speaking in a rapid, high-pitched voice. This nervous energy belies a deeply ingrained sense of insecurity. He is described as the most cowardly of the four captains, often being the first to retreat from a battle before a clear conclusion is reached, and he is quick to anger, possessing a short-tempered nature.

His background is the key to understanding his fierce loyalty and motivations. Gedorian hails from Gedra, described as the darkest and coldest region of the monster world. This humble and harsh origin stands in stark contrast to the more elite, pure-blooded members of the Crisis Empire. Because he was given his prestigious position by General Jark despite his lowly roots, Gedorian harbors an intense, almost desperate gratitude and loyalty toward the general. His obsession with his rank and status is far stronger than that of the other three captains, who are pure Crisis people and often look down on him. This deep-seated inferiority complex fuels his constant fear of being replaced or having his accomplishments stolen, making him highly jealous of any newcomer who might threaten his standing.

Within the crisis empire, Gedorian has a complex web of relationships. He is often looked down upon by Naval Commander Bosgun and Spy Staff Maribaron due to his impure lineage and erratic behavior. However, he is known to have collaborated frequently with Armored Captain Gatezone, who, like Gedorian, is not a pure Crisis being and is relatively unconcerned with status, making their partnership more practical and less strained. He also feels a palpable rivalry and later a murderous rage toward Colonel Dasmader, a special inspector sent by Emperor Crisis, viewing him as a direct threat to his position. His role in the story is primarily that of a recurring field commander who continuously devises schemes to defeat the hero, Kamen Rider BLACK RX.

Gedorian's character arc culminates in a notable act of desperate sacrifice. When Emperor Crisis, displeased with the stalled invasion, sends a final clock that will count down to the execution of all four captains, Gedorian volunteers for a last-ditch effort. He unleashes his ultimate weapon, a powerful monster named Gedoll Ridoll, which he cultivated from his own cells. In a final act of fanatical devotion, after his initial attack fails and he is betrayed by his fellow commanders who attempt to eliminate him, Gedorian uses himself as a medium to channel the immense energy of the Crisis Fortress directly into Gedoll Ridoll. He gives his life to empower his creation, pouring his very life force into the monster to ensure the mission might be completed, as the energy backlash ultimately causes him to disintegrate.

In terms of abilities, Gedorian is an agile fighter who makes use of his small size and light, quick movements in combat. His primary offensive weapon is the ability to fire destructive energy beams, which he can discharge from both of his hands and from the forehead of his visor-like compound eye. Beyond his physical powers, his most notable ability is his profound knowledge of alien lifeforms and technology, which he utilizes to create and cultivate the strange creatures under his command.
