Margo X is a character from the 1984 mecha anime series Chō Kōsoku Galvion. He serves as a loyal and capable subordinate to Henry McMillan, a key figure within the secret organization known as Shadow. In his role within Shadow, Margo X is characterized as a calm, composed, and professional combatant. He stands in contrast to his frequent partner, Johnny Crime, having a different appearance yet working in well-coordinated tandem with him to carry out missions. His primary function within the narrative is as an antagonist who directly opposes the protagonists of the Circus team, carrying out orders that involve sabotage, pursuit, and direct confrontation. As the story progresses, Margo X becomes a recurring threat, piloting a dedicated transforming mecha called the Goblin, a machine characterized by heavy armor and powerful weaponry that reflects his methodical fighting style. His relationship with his superior, Henry McMillan, is marked by unwavering loyalty and obedience. While his on-screen presence was limited due to the series' premature conclusion after 22 episodes, planned future storylines would have expanded his role considerably. In the intended continuation of the series, he and Johnny Crime would have been tasked by Henry with leading forces to hunt down the Circus team after they were forced into a guerrilla existence, highlighting his function as a persistent and capable field commander. His personal background and deeper motivations were not explored in the aired episodes, but the planned narratives indicate he was meant to have a more prominent part in the escalating conflict between the Circus and Henry's organization.
