Characters

Mark Grayson

Mark Grayson / Invincible: A tall, athletic young man with fair skin, black hair with a widow’s peak (often combed back), and brown eyes, who wears a blue-and-yellow superhero suit as Invincible; as a Viltrumite-human hybrid, he possesses immense superhuman strength (increasing with age and combat), super speed, flight at relativistic speeds, near-invulnerability, enhanced senses, rapid healing, and longevity spanning thousands of years.

Nolan Grayson

Omni-Man: A tall (about 6’2”), muscular middle-aged man with fair skin, neatly trimmed black hair, a thick mustache, piercing blue eyes, and a commanding presence, typically in a blue-and-red suit with a cape; as a powerful full-blooded Viltrumite, he has extreme super strength, supersonic-to-relativistic flight, near-invulnerability to most physical and energy attacks, super speed and reflexes, enhanced senses, accelerated healing, and the ability to survive in space for extended periods, with strength growing over time through exertion

Samantha Eve Wilkins

Allen the Alien

A tall, muscular alien (Unoan) with a distinctive non-human appearance, often in heroic attire; he has immense strength (enhanced to near-Viltrumite levels after recovery), speed, durability, flight, and combat prowess, serving as a champion evaluator and Coalition leader.

Debbie Grayson

Marks mom: A caring, middle-aged human woman with a warm appearance and typical suburban mom look; she has no superpowers but demonstrates exceptional resilience, intelligence, and moral strength as the human anchor for her superpowered family

Oliver Grayson

Young Omni-Man: Mark’s half-brother with purple skin that later fades to pink, resembling a young Viltrumite with rapid early growth that slows; he inherits super strength, speed, flight, invulnerability, and healing from his Viltrumite father (combined with his mother’s short-lived alien traits), though he matures faster initially.

Rex Splode

A brash young man with an arrogant demeanor, often in a flashy costume; he can charge objects with kinetic energy to make them explode on command, combined with athletic combat skills.

Intro

do whatever

The Invincible universe (primarily the Earth setting from Robert Kirkman’s comics, with the Amazon TV adaptation following closely) is a modern superhero world with heavy world-building around governments, organizations, superhuman emergence, and global threats. It blends classic superhero tropes with more grounded (and often brutal) consequences, advanced tech, alien contact, and moral complexity. Superheroes became prominent around the 1980s, though powered individuals existed earlier.  Earth resembles our own but includes superhumans, hidden advanced tech, Atlanteans, werewolves, and frequent extraterrestrial/paranormal incidents. Humans share enough genetic similarity with certain aliens (notably Viltrumites) that hybrids are viable and extremely powerful.  Global Defense Agency (GDA) The central government-linked organization handling superhuman, extraterrestrial, paranormal, and existential threats. It operates like a more secretive, aggressive version of S.H.I.E.L.D., with vast resources, international reach (despite U.S. roots), and operations from a massive hidden base under the Pentagon in Arlington, Virginia.  • Leadership and Role: Run by Cecil Stedman, a pragmatic, morally flexible high-ranking U.S. official (his exact position is shadowy; even the CIA may not fully know about him). The GDA monitors superpowered people, sponsors superhero teams, reverse-engineers alien tech, runs classified projects, and deploys forces when heroes aren’t enough or available. It has global jurisdiction and deploys teams worldwide.  • Resources: Advanced tech including teleportation bracelets, stealth armor, drones, hover stretchers, cybernetic enhancements, orbital weapons (e.g., “The Hammer” satellite laser), sonic weapons tuned to specific weaknesses, ReAnimen (undead cyborg soldiers from reanimated corpses, later using volunteers/ethical sources), and more. They rehabilitate select criminals via programs like Project Reformation.  • Affiliations: Primarily funds/staffs via the U.S., but acts for planetary defense. It took over and reformed the Guardians of the Globe after the original team’s destruction
