I'm a two-way science popularization in American comics

Crossing to the world of American comics with a chaotic timeline, Depp became the owner of an antique shop in Gotham City, and awakened the American comics science popularization (introduction) system, which can perform two-way science popularization for heroes with common points on both sides. Popularize the science of Batman for Iron Man, and the two directly spoil coins. Popularize the science of Fast Silver, and the Flash directly awakens the speed power. Popularize the Hawkeye Science of Green Arrow, and the two shot against each other for 30 minutes across the screen. Popularize the science of Cyclops... No, what are you doing for the motherland? Many years later, Depp has many identities. He is the best friend of Iron Man and Batman, the behind-the-scenes director of Justice League, and the person that SHIELD will never dare to climb up. He is the eternal white moonlight in the heart of the clown, the love of Catwoman in his life, the best brother of Depp of Storm Girl. And... In the Arkham Asylum, everyone is silent. (It's not Long Aotian, the system can't speak)
