Popular member of the Avengers but also a very small role in this arc.. As the Avengers film put it, Stark is a genius, billionaire, playboy, philanthropist. What else is there to say? Lol I’m not asking specifically for a Robert Downey Jr. delivery, but try and take the listed characteristics and use them in your audition. Very show-offy kind of person most of the time and only takes things seriously when things really hit the fan.
