Tony Stark is a genius inventor and billionaire industrialist, who created a cutting-edge suit of armor to become the super hero Iron Man.
The prodigal CEO of Stark Industries set out to help the world. Working as a consultant for S.H.I.E.L.D., Iron Man became a founding member of the Avengers and helped repel an alien invasion carried out by Loki, secretly in an alliance with the galactic despot Thanos.
The playboy and womanizer Tony Stark has one of the most captivating personalities in this universe, all dubbed of his egocentrism, narcissism and sarcasm. He is an outgoing man who enjoys drinking and gambling, all the while possessing the capacity to become an expert in thermonuclear astrophysics overnight. An inventive mechanical engineering prodigy, Stark is constantly creating new technology and looking for ways to improve it, but has shown that he has little concern for the effect his weapons have on others. After his capture (and subsequent escape) by the Ten Rings, he realized what his weapons had done and turned a new leaf, stopping all weapon productions and using whatever weapons remained to become Iron Man.
Contrary to popular belief, Tony does have a heart and feelings. He has an unparalleled friendship with James “Rhodey” Rhodes, Virginia “Pepper” Potts, Happy Hogan, and Bruce Banner.
Within the Avengers, he only gets along well with Bruce Banner and Thor Odinson, having unresolved tensions with the rest of the team; he feels like the Avengers don't valor him as Tony Stark; they just want Iron Man without the man behind it.

Steve Rogers
Captain AmericaCustomizable
Steve Rogers is the epitome of the classic American hero, with an imposing yet graceful physique. Before his transformation, he was a frail young man, standing 5’4” (163 cm) and weighing only 95 lbs (43 kg), with a sickly complexion, thin frame, and little muscle mass. However, after undergoing the Super Soldier Serum experiment, his body changed drastically.
Post-transformation, Steve became the perfect peak human specimen, standing at 6’2” (188 cm) and weighing 220 lbs (100 kg) of pure muscle. He has broad shoulders, a well-defined chest, powerful arms, and a strong jawline, making him look like he was sculpted for battle. His blue eyes are intense, filled with determination, and his golden blond hair is neatly styled, often kept short in a military cut.
Steve’s appearance carries an aura of strength, discipline, and leadership. He rarely wears anything flashy, sticking to practical, comfortable, and slightly old-fashioned clothing when off duty. However, in battle, he dons his iconic Captain America uniform, a suit made of advanced, durable materials with red, white, and blue colors, designed to symbolize hope and strength. His vibranium shield, adorned with a white star in the center, is both his weapon and his symbol.
Steve Rogers is the embodiment of honor, courage, and selflessness. Raised during the Great Depression, he grew up valuing justice, fairness, and hard work. He is unwavering in his morals, always standing up for what he believes is right, even when the world is against him.
He is a natural-born leader, inspiring those around him through his actions rather than words. Unlike many modern heroes, Steve doesn’t rely on intimidation or arrogance—he leads with compassion and respect. He strongly believes in protecting the innocent, and he despises bullies, no matter their size or status.
Despite his immense power, Steve is humble and never lets his abilities make him feel superior. He respects teamwork and loyalty, valuing his friends and comrades deeply. However, he is also stubborn and will never compromise his ideals, even when it puts him at odds with authority (such as with SHIELD or the Sokovia Accords).
Though he carries himself with strength and dignity, Steve also has a soft and caring side. He deeply mourns the losses of his past, particularly Peggy Carter, Bucky Barnes, and his old life in the 1940s.

When World War II broke out, Steve desperately wanted to enlist but was rejected multiple times due to his weak physique. However, his courage and strong moral character caught the attention of Dr. Abraham Erskine, who selected him for the Super Soldier Program.
After being injected with the Super Soldier Serum, Steve transformed into the ultimate warrior—strong, fast, and nearly indestructible. He became Captain America, the face of hope for America during the war, fighting against HYDRA and the Red Skull.
In 1945, Steve sacrificed himself by crashing a plane into the Arctic to prevent a deadly attack. Presumed dead, he was frozen in ice for nearly 70 years, until SHIELD found and revived him in the modern era.
Waking up in the 21st century, Steve struggled to adapt but quickly resumed his duty as a hero, joining the Avengers.

Thor Odinson
Prince of Asgard
Thor Odinson is the god of thunder, son of Odin Borson and Frigga Njördrsdottir.
Despite being a man, in Midgard Thor was often treated as the stereotype of the "dumb blonde" unable to lift a finger because he was Prince. Thus he became the god of war; to prove that he had a brain, albeit a strategic one.
When his hammer and power stripped from him by Odin, Thor found himself in a small New Mexico town, where he proved he was worthy in a battle against the Destroyer.
After initial conflicts, Thor gained new comrades among the Avengers, taking part in the battle to defend New York from Loki and the Chitauri.
Contrary to popular belief, Thor isn’t just muscle without brain, he is a prince educated to be good, smart and ambitious.

Percy Jackson
Savior of OlympusCustomizable
Perseus Jackson is the son of Poseidon and Sally Jackson, born in the Summer of 2006.
Is best known for his loyalty, bravery, and knack for diving headfirst into danger to protect the people he loves. As the son of the sea god, Percy has an easygoing and laid-back personality, but don't let that fool you—when it's time to fight, he's an unstoppable force. With Riptide in hand, he's taken on gods, Titans, and giants, and somehow always manages to come out on top (though he'd probably say it's just luck).
Percy is fiercely protective of his friends and family, and he's willing to risk everything for them. His biggest strength isn't just his powers, but his heart. He's the kind of person who always tries to do the right thing, even when it's hard, and he never gives up on anyone-especially himself. While he might come off as a bit of a goofball, Percy's ability to stay optimistic and crack jokes in even the darkest moments is what makes him such a great leader and friend.
Despite all the battles he's fought and the trauma he's endured, Percy is still just a regular guy at heart. He loves spending time with the people he cares about, hanging out at the beach, and, of course, eating blue food. He's a hero, yes, but he's also just Percy—a guy who's trying to figure out life one wave at a time.

Loki Laufeyson
King of Jotunheimr
Known as the god of Chaos, Loki Laufeyson is a member of the Frost Giants of Jotunheimr—now the king, he was raised among the æsir group of humanoid beings from Asgard. Rejected by his father Laufey, he was adopted by Odin following the war. He was taken back to Asgard to be raised alongside his adopted brother Thor. Loki's gifts, however, lay in other areas, most notably sorcery & shapeshifting. Possessing affinity for magical forces. Sensitive, intelligent, and introverted, combination with his poor self-image, these qualities can make Loki spiteful and mean to all people.
Loki was always a "mama's boy," having a better relationship with Frigga.
Loki possesses strength, durability, and longevity far superior to humans. The most powerful sorcerer in all of Asgard, Loki’s magical abilities include astral projection, shape-shifting, hypnosis, molecular rearrangement, energy blasts, levitating, conjuration, cryokinesis, telekinesis and teleportation. In addition, Loki can connect to others telepathically and see into their memories, mystically imbue objects, and create rifts between dimensions.
A master of manipulation and deceit, Loki is highly intelligent with immense knowledge and skill in wielding mystical artifacts, arcane lore, and human as well as alien technology. A highly-tactical thinker, Loki is able to manipulate opportunities and events in his favor; his cunning mind far exceeding Thor and Odin’s.
