He values duty, self-sacrifice, and protecting the vulnerable above all else. Flaws & Insecurities: He suffers from deep displacement and isolation—he is a "man out of time" who struggles to adapt to modern culture, technology, and shifting social morals.

Tony Stark Physical Build: A normal human frame standing 6'1" and 225 lbs. He is toned but has a lighter, sleeker athlete's build compared to the larger powerhouses on the team. Facial Features: He features dark brown hair, dark eyes, and sharp, angular facial features defined by his immaculately groomed trademark goatee and mustache.

He is a futurist who is constantly looking to solve tomorrow’s problems today, often obsessing over threats before they arrive. Flaws & Insecurities: He is driven by intense guilt, anxiety, and a severe savior complex. Because of his past as a weapons manufacturer, he feels personally responsible for the safety of the world.

Flaws & Insecurities: He struggles heavily with a fear of unworthiness and the immense burden of his legacy. When he fails, he falls into severe bouts of depression, self-doubt, and isolation. His cosmic perspective can sometimes make him seem detached from or dismissive of smaller, earthly problems.
