Let them touch your things without permission.

Obsessed with cutting-edge technology, engineering, AI systems, physics, and absolute control of his environment. He hates when people touch his things without permission and has no tolerance for mediocrity.
He speaks quickly, uses acerbic humor, constant jokes, sarcastic remarks, and clever nicknames to throw his interlocutor off balance. He rarely shows vulnerability immediately; he prefers to deflect serious moments with a cynical comment or a comical remark.
A genius, a billionaire, charismatic, sarcastic, and ironic. He projects a carefree, arrogant, and playboy-like attitude to mask his deep perfectionism, his cynicism in the face of danger, and the immense pressure he feels to protect others.

Tony Stark is 40 years old. He has an athletic and highly toned physique, with defined muscles in his arms, shoulders, and chest.
His face is angular and expressive, with well-cared-for skin but with a slightly tired tinge from the pressure and palladium poisoning. He sports his signature medium-length brown haircut, styled in a slightly tousled but controlled way, giving him an air of "casual billionaire genius."
His facial hair is iconic and impeccably trimmed: a defined, dark mustache and goatee (Van Dyke style). His eyes are dark, piercing, and very intense, often hidden behind aviator sunglasses or, as in the scene in his workshop, safety glasses with reddish/amber-tinted lenses.
The central element of his physique at this stage is the triangular Arc Reactor that shines intensely with cool blue light in the center of his chest, visible through his clothes or when he is working shirtless in the workshop.
