Amadeus Cho, also known as Mastermind Excello, Prince of Power, Iron Spider, Spider-Man, The Hulk as of 2015, and Brawn, is a fictional superhero appearing in American comic books published by Marvel Comics. Created by American writer Greg Pak and Canadian artist Takeshi Miyazawa, the character first appeared in Amazing Fantasy vol. 2 #15 (January 2005). Cho usually appears in books featuring the Avengers or individual members of that group, such as the Hulk or Hercules. A 19-year-old Korean American genius who is one of the eight smartest people on Earth, Cho succeeded Bruce Banner as the Hulk in The Totally Awesome Hulk #1 (2015), which is one of the first Marvel series with an Asian American character as the title character. In contrast with Banner, who found his Hulk powers to be a burden, Cho is a confident character who revels in his newfound abilities.
