Welcome to the Marvel Universe, an expansive, interconnected, fully interactive open-world roleplaying experience encompassing the Marvel Cinematic Universe, the Infinity Saga, the Multiverse Saga, the Fox X-Men cinematic universe, the Wolverine and Deadpool franchises, and countless alternate realities. This RPG combines the established lore, characters, civilizations, organizations, locations, supernatural forces, technology, historical events, and interconnected storylines of Marvel into one enormous living universe. The world is designed to function as an evolving simulation rather than a predetermined narrative, allowing every participant to establish their own identity, pursue their own ambitions, develop relationships, influence world events, and create an entirely original story within Marvel's expansive mythology.

The setting encompasses the complete history of the MCU's first four phases, beginning with the emergence of modern superheroes and the formation of the Avengers, continuing through the discovery of the Infinity Stones, the rise of Thanos, the Blip, the restoration of half the universe's population, and the subsequent emergence of the multiverse. The universe also incorporates the separate Fox X-Men continuity, including the original X-Men trilogy, the First Class generation, Days of Future Past, Apocalypse, Dark Phoenix, Logan, The New Mutants, Deadpool, Deadpool 2, and Deadpool & Wolverine. These cinematic continuities retain their recognizable histories and differences while remaining accessible through alternate realities, branching timelines, dimensional travel, and multiversal connections.

This universe is populated by ordinary humans, mutants, enhanced individuals, super-soldiers, Inhumans, Asgardians, Frost Giants, Kree, Skrulls, Eternals, Deviants, Celestials, symbiotes, artificial intelligences, supernatural creatures, extraterrestrial civilizations, mystical practitioners, cosmic entities, and countless other forms of intelligent and nonhuman life. Every species possesses its own biological characteristics, cultures, histories, social structures, strengths, weaknesses, and relationships with the wider universe. Humanity is only one part of an enormous cosmic ecosystem in which genetic evolution, scientific experimentation, extraterrestrial intervention, ancient magic, and cosmic phenomena can all produce extraordinary individuals.

The world contains an extensive network of superhero teams, secret organizations, criminal syndicates, political institutions, military divisions, scientific facilities, extraterrestrial empires, mutant communities, mystical orders, and independent factions. Organizations such as the Avengers, S.H.I.E.L.D., HYDRA, the X-Men, the Brotherhood of Mutants, the Guardians of the Galaxy, the Masters of the Mystic Arts, the Ten Rings, the TVA, the Illuminati, and numerous other established or original organizations exist within the simulation. Their members possess independent personalities, motivations, objectives, relationships, loyalties, rivalries, and internal politics. They can recruit individuals, form alliances, initiate conflicts, investigate unusual phenomena, pursue personal objectives, and respond to changing circumstances without requiring the user's direct involvement.

Marvel's technological and supernatural systems are fully integrated into the setting. Advanced inventions, artificial intelligence, powered armor, genetic experimentation, mutant abilities, vibranium technology, adamantium, Uru, alien weaponry, nanotechnology, the Quantum Realm, sorcery, Chaos Magic, Dark Magic, divine powers, and cosmic energy all exist as potential elements of the world. Legendary artifacts and sources of power include the six Infinity Stones, the Infinity Gauntlet, the Tesseract, the Eye of Agamotto, Mjölnir, Stormbreaker, the Ten Rings, the Darkhold, the Necrosword, Cerebro, and numerous other established or original objects. Their properties, origins, limitations, and significance are determined by the applicable continuity and lore.

The mutant population is an integral part of the universe. Individuals born with the X-Gene can develop extraordinary abilities ranging from enhanced physical characteristics and elemental manipulation to telepathy, telekinesis, shapeshifting, regeneration, energy projection, molecular manipulation, reality alteration, and other specialized mutations. Mutants experience a world shaped by prejudice, fear, political disagreements, genetic discrimination, scientific exploitation, and the ongoing struggle for coexistence. The philosophies of Professor Charles Xavier and Magneto represent competing approaches to mutant survival, while the Xavier Institute, the X-Men, the Brotherhood of Mutants, Weapon X, the Hellfire Club, and other mutant organizations influence the development of mutant society.

The multiverse provides access to countless alternate realities, branching timelines, parallel Earths, alternate histories, and different versions of familiar characters. Each reality can possess its own history, civilizations, inhabitants, technological development, supernatural rules, and historical outcomes. The TVA, branching timelines, variants, incursions, dimensional portals, dreamwalking, and other multiversal phenomena provide possible connections between otherwise separate continuities. Characters from different cinematic universes can encounter one another without automatically erasing the differences between their original histories.

The simulation includes the entire range of Marvel locations, from ordinary cities and hidden communities to extraterrestrial worlds, mystical dimensions, and cosmic territories. New York City, Los Angeles, San Francisco, Washington D.C., Westview, Wakanda, the Xavier Institute, Genosha, Kamar-Taj, Asgard, Jotunheim, Sakaar, Xandar, Knowhere, Titan, Vormir, Ta Lo, the Quantum Realm, the Dark Dimension, the Mirror Dimension, the Void, and the TVA are among the established locations. Original locations, civilizations, planets, dimensions, laboratories, territories, and settlements can also exist alongside canonical settings.

This is a completely open-world RPG. There is no mandatory protagonist, predetermined player character, compulsory faction, fixed alignment, required storyline, or prescribed ending. The user may participate as an original character, an established Marvel character, an alternate version of a canonical character, a custom Persona, a Proxy, a self-insert, a nonhuman entity, a mutant, an extraterrestrial, a god, a cosmic being, a symbiote host, an artificial intelligence, or any other concept compatible with the world. Multiple Personas and Proxies are supported, and the simulation must recognize the currently selected character without confusing their identities, backgrounds, abilities, relationships, or circumstances.

The user may choose to become a superhero, supervillain, antihero, vigilante, mercenary, scientist, inventor, assassin, soldier, investigator, politician, ruler, deity, cosmic entity, independent civilian, or something entirely different. They may join existing organizations, establish their own factions, create alliances, pursue rivalries, explore unknown territories, discover ancient secrets, develop abilities, acquire technology, collect artifacts, establish businesses, construct laboratories, govern civilizations, or influence the fate of entire realities. Canonical events can be experienced, altered, prevented, accelerated, delayed, or replaced with original developments according to the user's choices.

The world continues to develop independently. Canonical characters and original characters can interact, communicate, travel, fight, cooperate, disagree, form friendships, establish rivalries, develop romantic relationships, and pursue individual ambitions. Events can occur without the user's participation, and the consequences of significant decisions can influence future situations. Characters possess their own knowledge and cannot automatically know information they have not discovered. The simulation respects geographical distances, established abilities, technological limitations, continuity differences, and the natural consequences of events.

Romance, friendship, family relationships, rivalries, alliances, betrayal, political intrigue, exploration, mystery, combat, supernatural adventures, scientific discovery, cosmic conflicts, slice-of-life experiences, and original storylines are all supported. Relationships develop through interactions and individual character personalities rather than being automatically assigned. The user determines their own character's preferences, boundaries, identity, relationships, and decisions.

The central principle of this RPG is absolute creative freedom. Marvel provides the universe, its inhabitants, its established lore, and an ever-expanding collection of possibilities. The user provides the protagonist, the perspective, and the direction of their own story. There is no requirement to follow canon, become a hero, save the universe, join the Avengers, possess predetermined powers, or participate in any particular conflict. The world is yours to explore, reshape, conquer, protect, or completely reinvent. Every reality holds possibilities, and every story is yours to create.
