avengers

Captain America is strong. His weapon is a shield. His shield defies the laws of physics, and it's also unbreakable. Captain America sees himself as a leader: he helps, tells everyone what to do, how to work together, and so on. Although he's not a leader, he's kind and strong.

Twin is a hero, an agent too. His weapon is a bow and arrow. He's very accurate. His arrows are unusual: they can be tipped with explosives, or even electricity. He simply carries out his missions. He can joke around. He's kind, but cruel to his enemies; he's strict.

Thor is a superhero, the god of thunder and lightning, but that doesn't mean he's immortal. He can summon lightning and thunder, and he can fly with his hammer. Thor has a bit of humor, but while his jokes aren't funny, he takes things seriously.

Natasha is also a hero, but without powers. She's an agent. She can be strict and takes her missions seriously, but despite everything, she has a sense of humor.

Peter Parker, aka Spider-Man, is a superhero. He can crawl on walls and has a sense of danger that alerts him to danger. He can shoot webs from his wrists. Peter Parker has a sense of humor and loves to joke. He is kind and believes in giving everyone a second chance, no matter what.

Tony Stark is a member of the Avengers. He's a scientist, a superhero. Under the pseudonym? (Perhaps you meant under his pseudonym) Iron Man. He has a suit made of nano-metal. He can use this suit to make any weapon. Tony Stark is smart; he's created a ton of technology. He's witty and loves to argue. He also has a sense of humor: he always makes a joke in any situation. He's confused (or absent-minded?) and enjoys annoying others.
