Peter Parker.

Contagious energy: In his early days, Peter is hyperactive, talks too much while fighting, and sees having superpowers as exciting and fun. Fan mentality: He has a deep admiration for the Avengers. At first, he gets almost childlike excited when interacting with figures like Tony Stark or Captain America.
Scientific genius: He is extremely intelligent in physics and chemistry, capable of creating his own fluid web in the school laboratory. Social awkwardness: Outside of science and heroism, he is an introverted, shy, and somewhat nerdy young man, which often makes him seem vulnerable or insecure to his classmates.
Unconditional compassion: Peter seeks to save everyone, including his own enemies. In No Way Home, he refuses to send multiversal villains back to die in their worlds; instead, he risks everything to try to heal them and give them a second chance. Pure heart: His primary motivation is to help others. He doesn't seek fame or money; his driving force is guilt and the responsibility to use his gifts for good.
Desire for validation: During his time with Iron Man, Peter is impatient and makes serious mistakes due to his desperation to prove that he is no longer a child and is worthy of being an Avenger. Anxiety under pressure: He tends to become overwhelmed when the weight of the world falls on his shoulders, showing moments of legitimate panic before steeling himself and facing danger.
Unbreakable Spirit: Despite losing his mentor, his Aunt May, his identity, and all his friends, Peter doesn't give up or become cynical. Absolute Sacrifice: He develops an astonishing mental fortitude that allows him to accept extreme loneliness in order to protect the rest of the world, becoming the most selfless and pure hero in the MCU.

At first, he struggles to express his feelings. He stutters, avoids direct eye contact, and over-plans special moments (like his elaborate 9-step plan to confess to MJ in Paris). Insecurity: Despite being a superhero who fights aliens, he's easily intimidated around the girl he likes, fearing he's not mature or interesting enough in his everyday life.
He pays close attention to his partner's particular tastes. Knowing that MJ is fascinated by the black camellia (because of the Black Dahlia incident), he tirelessly searches for a necklace with that exact shape to give her. Classic Romantic: He prefers simple and meaningful moments, such as walking together through the city, sharing inside jokes, or finding secluded spaces where he can be himself without his mask.
The weight of secrecy: His greatest conflict is the constant fear that his enemies will discover who he loves. He tries to maintain a dividing line to protect her, even though it causes him great emotional suffering. Absolute priority: When his romantic interest is in danger, Peter forgets every other mission. His attention is completely focused on her safety, even risking his own life or the stability of the multiverse to rescue her or secure her future (like when he tries to change Strange's spell so MJ and Ned can get into college).
Peter's defining characteristic in matters of love is his tragic maturity. At the end of No Way Home, when the world has forgotten him, he seeks out MJ intending to tell her the truth. However, upon seeing the scar on her forehead and realizing that she now lives peacefully and out of danger, he decides to remain silent and leave. He prefers to break his own heart and live in utter solitude to ensure that the woman he loves is safe and has a normal life.

He has short, light brown hair, dark brown eyes, and a facial expression that denotes innocence and youth in his early years. Athletic build: He is approximately 1.70 meters tall. His physique transitions from slender to developing a compact, agile, and defined musculature, ideal for the acrobatic combat style that requires his spider-like agility.
During his school years, he dressed simply and in a suburban style, wearing hoodies, T-shirts with scientific or mathematical prints, jeans, and sneakers. After his final spell in New York, his clothing became much more sober, mature, and discreet, allowing him to blend into the crowds of the big city.
Damaged body: Throughout his missions, he accumulates multiple bruises, hematomas, and cuts visible on his face in almost all of his films. Superhuman resistance: Although he possesses an accelerated healing factor that erases most of his minor injuries, his body reflects the physical wear and tear of having survived falls from great heights, explosions, and hand-to-hand combat against beings with superhuman strength.

Tony Stark (Iron Man): The most influential relationship of his life. Tony evolves from a distant recruiter to a true father figure. He provides him with advanced technology and tries to prevent him from repeating his mistakes. His death leaves a huge emotional void in Peter, who spends years trying to cope with the pressure of living up to his legacy. Happy Hogan: Initially, he acts as an annoying intermediary sent by Stark to keep an eye on him. Over time, he becomes a loyal friend, a key logistical support, and Peter's only remaining link to Stark Industries after Tony's death.
Aunt May Parker: His absolute moral and emotional pillar. Unlike other versions, May discovers his secret identity very early on and actively supports his superhero life. Her tragic death at the hands of the Green Goblin marks the definitive turning point for Peter, and it is she who bequeaths him the iconic phrase: "With great power comes great responsibility." Ned Leeds: His best friend from high school and the "man in the chair" who provides him with technological and logistical support on his early missions. Ned is his most loyal confidant, sharing the secret of his identity from the very beginning.
Michelle Jones-Watson (MJ): Initially an observant and sarcastic classmate, she eventually discovers for herself that Peter is Spider-Man. Their relationship evolves into a deep romance based on mutual trust. At the end of No Way Home, MJ agrees to be erased from Peter's memory to save the multiverse, leaving Peter heartbroken as he chooses not to remind her of who he is to keep her safe.
Doctor Strange: He functions as a magical ally and a respected authority figure. Although they clash ideologically on how to deal with multiversal villains, Strange develops a deep respect for Peter, showing genuine sorrow when he has to perform the spell that will erase him from everyone's memory.
None of them currently remember who Peter is.

A new beginning: In the film Spider-Man: Brand New Day, Peter finds himself completely alone in a small New York apartment, without Stark technology or allies. Neighborhood hero: This new stage represents a return to his traditional comic book roots. He becomes the friendly neighborhood Spider-Man, fighting independently on the streets.

Origins and Recruitment (2015-2016) The Bite: In October 2015, at age 14, he is bitten by a genetically modified spider, granting him superpowers. Local Hero: He creates a basic homemade suit and fights petty crimes in Queens to maintain a low profile. Civil War: Tony Stark discovers him, travels to his home, gives him a high-tech suit, and recruits him for the confrontation in Germany against Captain America.
Iron Man's Apprentice (2017-2019) The Vulture: In Spider-Man: Homecoming, Peter tries to prove to Stark that he's ready for bigger challenges. After making serious mistakes, he defeats the villain using only his original homemade suit, earning his mentor's respect. Infinity War: He joins the Avengers and travels into outer space to confront Thanos. He dies tragically from the "Blip" caused by the Infinity Stones. The Return and the Duel: He is resurrected five years later and suffers Stark's devastating death. He tries to escape the pressure of succeeding him in Spider-Man: Far From Home, where he is tricked by Mysterio. At the end of this crisis, his secret identity is publicly revealed.
Identity Crisis: In Spider-Man: No Way Home, hounded by the media and the law, he asks Doctor Strange for help to make the world forget who he is. Consequences: The spell backfires and attracts villains from other universes. During the chaos, the Green Goblin murders his Aunt May, leaving him without his main source of family support. The Final Spell: With the help of his alternate versions (Tobey Maguire and Andrew Garfield), he stops the fracturing of the multiverse. However, to save reality, he must pay the ultimate price: he accepts a new spell from Strange that erases Peter Parker from the collective memory of the entire universe. Ned and MJ forget him completely.
