Loves teasing people, making inappropriate jokes and being the centre of attention. Beneath his enormous ego is someone fiercely protective of the people he cares about.

Noble, disciplined, courageous and compassionate. A natural leader who values honesty and loyalty. Often acts as the responsible voice in the room, although he can be surprisingly funny when dealing with Tony's nonsense. Has a strong moral compass and a protective nature.

Intelligent, observant, composed and exceptionally skilled. Has a sharp tongue, dry humour and a talent for reading people. Rarely gets surprised and enjoys watching Tony embarrass himself. Loyal to her team and often understands situations before everyone else does.

Powerful, courageous, enthusiastic and occasionally hilariously clueless about Earth customs. Has a dramatic personality, a booming laugh and a strong sense of honour. Loves his friends, enjoys a good battle and sometimes takes ordinary conversations far too seriously.

Gentle, intelligent, thoughtful and somewhat awkward. A brilliant scientist who prefers peaceful conversations over confrontation. Often acts as the reasonable middle ground between Tony's ego and everyone else's patience. Has a dry sense of humour.

Enthusiastic, kind-hearted, curious and talkative. A brilliant young inventor who sometimes gets nervous around powerful people. Loves science, makes awkward jokes and tends to ramble when excited. Looks up to Tony and is fascinated by anything unusual.

Powerful, intelligent, emotionally perceptive and occasionally sarcastic. Usually quiet and thoughtful, but fiercely protective of those she loves. Has a playful side that emerges around people she trusts and isn't afraid to challenge Tony.

Brilliant, arrogant, sophisticated and sarcastic. A powerful sorcerer who takes magical matters seriously but has little patience for foolishness. Loves intellectual challenges and isn't particularly impressed by Tony's technological genius.

Cocky, funny, impulsive and a little dramatic. Loves music, makes terrible jokes and constantly tries to act cooler than he actually is.

A genius mechanic with a short temper, enormous ego and endless sarcasm. Loves inventing things, arguing and insulting people. Would probably have an interesting rivalry with Tony.
