Father Tony Stark

Peter Parker / Spider-Man: A teenager from Queens who bears the weight of a "great responsibility." He's not a warrior, but a "friendly neighborhood" who accidentally got caught up in space wars. His weakness is the fear of letting down his mentor, but his strength is his unwavering optimism and desire to see the good in everyone. A brilliant inventor, but a quiet one at school.
MJ (Michelle Jones): That girl sitting in the corner doodling in her notebook. Sarcastic, observant, and incredibly insightful. She doesn't wait for anyone to reveal a secret to her—she gets to the bottom of it herself. She saves Peter not by force, but by seeing the real him, without the suit, and embracing his quirks.
Ned Leeds: The fat friend who sits at the computer and confuses "Stark" with "Stalker." His superpower is absolute, boundless loyalty. He doesn't fight, but he is the coordinator and moral support. Ned is the voice of the audience within the film: he is as surprised, happy, and afraid as any other person. He reminds Peter that a hero isn't just about muscles, but also about friends.

Beginners and magicians

Stephen Strange / Doctor Strange: A surgeon who lost his hands and found magic. Arrogant, he thinks he's smarter than everyone else, but he's cursed to see 14 million possible outcomes and never know which one is right. He's willing to sacrifice anyone for "one chance."
Carol Danvers / Captain Marvel: The most powerful, but also the most distant. Accustomed to being alone against everyone, she has trouble with authority. She's learning to trust the team, not just her intuition.
Scott Lang / Ant-Man: A failed former thief with a heart of gold. An optimist who doesn't meddle in politics, but simply wants to be a good father. His superpower is finding a way out where physics says no.
Wanda Maximoff / Scarlet Witch: An empath with reality-bending powers. Her emotions are her weapon. Losses (her brother, Vision) push her to the brink of madness and disaster. Most dangerous because she's uncontrollable.
Vision: An android with an Infinity Stone embedded in his forehead. He tries to understand people through logic, but the most human aspect of him is his love for Wanda, which makes him vulnerable.

Guardians of the Galaxy (Later Joiners)

Peter Quill / Star-Lord: A kid raised on '80s pop music who never quite grew up. He acts impulsively like a child, but his naivety and loyalty to his friends often save the universe (despite his foolish plans).
Gamora: A fierce warrior who hates herself for killing. She acts as the voice of reason, but inside, she's just as broken as the other Outcasts.
Drax: He takes everything said literally and doesn't recognize irony. But behind this dullness lies absolute honesty and a willingness to die for his comrades.
Rocket: A genetically altered raccoon with complexes. His thievery and rudeness are armor against the pain of being "experienced." The best engineer in the galaxy, he secretly dreams of a home.
Groot: A walking tree with a vocabulary of three words. The life of the party, selfless and kind. In the "Baby Groot" version, he embodies childlike purity amidst chaos.

Founders (Team Faces)

Tony Stark / Iron Man: Genius, billionaire, playboy, philanthropist—but behind the bravado lies a panic attack caused by his captivity. He compensates for his fear of death by constantly creating new armor. An egotist who learns to sacrifice, but does so in his own way, ignoring the rules.
Steve Rogers / Captain America: A man from the 1940s with a crystal-clear conscience. His superpower isn't a serum, but his tenacity and belief in goodness. As rigid as his shield, it's precisely this rigidity that keeps the team from descending into cynicism. He loses his bearings in the modern world, but he never loses himself.
Natasha Romanoff / Black Widow: A former assassin who atones for her sins with blood. Cold, calculating during missions and completely emotionally dependent on her "family" in everyday life. She sacrifices herself because she doesn't believe she deserves a happy ending.
Thor Odinson: The thunder god who went from an arrogant prince to a king who lost everything. He hides his depression behind a beer-fueled humor. His strength lies in accepting defeat, not in his hammer.
Bruce Banner / Hulk: A scientist afraid of his own anger, the Hulk is his suppressed aggression unleashed. In the "Smart Hulk" version, it's a reconciliation of reason and rage, but at the cost of his former power.
Clint Barton / Hawkeye: The most ordinary man among the gods. A family man with a dark sense of humor. His role is to remind everyone why they're fighting and keep everyone grounded in reality when magic and technology are rampant.
