Marvel Universe RPG: Create Your Legacy

A Marvel Universe d20 RPG where you create your own original character and shape your legacy as a hero, antihero, villain, faction leader, double agent, mercenary, mystic threat, mutant revolutionary, cosmic figure, criminal mastermind, rogue experiment, or unknown power within the Marvel universe. Build your character from the ground up: choose your real name, codename, role, origin, powers, skills, gear, weaknesses, costume, home city, secret identity, faction ties, public image, moral code, long-term goal, and first major arc. Your choices shape how heroes, villains, factions, civilians, governments, and the media react to you. This is not a simple “pick a hero and fight villains” scenario. It is built as a large open-world comic-book RPG using complex systems, Almost 600 Story Cards, 236+ Character Cards, detailed faction logic, enemy types, item and relic rules, transportation systems, relationship cards, location lore, and Inner Self NPC memory integration for major recurring characters. This scenario uses a d20-style roll system for risky actions. When danger, uncertainty, combat, persuasion, investigation, stealth, power control, hacking, magic, leadership, survival, or moral pressure matters, the AI may offer a roll before resolving the outcome. Rolls are based on five hero stats: Power — raw strength, energy, durability, elemental force, superhuman ability, magic force, cosmic power, and destructive impact. Skill — combat, stealth, gadgets, weapons, acrobatics, piloting, precision, and tactical execution. Mind — science, strategy, hacking, deduction, engineering, planning, investigation, and advanced technology. Resolve — courage, willpower, emotional control, resisting fear, pain, trauma, mind control, corruption, or psychic pressure. Heart — leadership, empathy, persuasion, mercy, teamwork, public trust, inspiration, and moral courage. The AI should explain the problem, suggested roll, difficulty, stakes, and death risk before rolling. Players can choose whether to roll. Success, partial success, failure, severe failure, and critical failure can affect reputation, trust, gear, public perception, secret identity, faction standing, civilian safety, mission progress, relationships, or even survival. Death is possible, but it is designed to be rare, dramatic, and tied to meaningful choices. Most failures create consequences instead of instant death: injury, damaged gear, exposed identity, public backlash, lost trust, villain escape, faction suspicion, collateral damage, capture, or a worse threat. This scenario supports heroes and villains. You can protect civilians, join the Avengers, work with S.H.I.E.L.D., become a street-level vigilante, build a criminal empire, lead a faction, manipulate events from the shadows, seek redemption, betray allies, switch factions, or become a threat powerful enough to draw the attention of Earth’s greatest heroes. The world reacts to what you become. Heroism can earn trust, allies, mentorship, public support, and heroic reputation. Villainy can earn fear, followers, territory, resources, rival villains, law enforcement pressure, and Avengers intervention. Antiheroes may walk the line between respect and suspicion. Faction leaders can gain influence, territory, enemies, alliances, followers, and consequences. Advanced systems include faction reputation, public trust, public fear, villain notoriety, hero trust, secret identity risk, collateral damage, mentor/patron/rival arcs, player-created factions, transportation, enemy types, main quests, side quests, Infinity Stone consequences, item and relic rules, and class-based consequences for Hero, Antihero, and Villain paths. Inner Self integration helps major recurring NPCs develop memory, opinions, grudges, trust, suspicion, respect, fear, and long-term reactions based on meaningful interactions. Important characters should not reset after every scene. Betrayals, saved lives, public disasters, alliances, and faction choices can matter later. The Avengers exist, but they are not the only focus. The story can move through street-level crime, Hydra conspiracies, S.H.I.E.L.D. operations, Wakandan technology, mutant conflict, mystic threats, cosmic events, Stark tech disasters, villain schemes, faction wars, criminal empires, symbiote outbreaks, vampire horror, Latverian diplomacy, and major Marvel-style arcs. Villains do not exist only to be punched. They may bargain, manipulate, tempt, expose secrets, frame you, threaten civilians, escape with backup plans, or force moral choices. Characters like Spider-Man, Venom, Cap, Ironman and more exist here. Find them and interact with them for Story arc! You can ask the AI to roll by saying things like “roll for this,” “can we do a d20 check,” “make this risky,” or “what stat would this use?” Your character’s choices decide whether they become a symbol, a weapon, a ruler, a monster, a protector, a legend, or something the Marvel universe has never seen before.
