I Am Two-way Popular Science in the United States

Traveling to the chaotic world of Meiman, Depp became the owner of an antique shop in Gotham City, and awakened the Meiman science (introduction) system, which can conduct two-way science popularization for heroes who have something in common on both sides.
Give Iron Man popular science Batman, and the two directly throw coins.
For Quicksilver Popular Science Flash, Quicksilver directly awakens the speed force.
To Hawkeye's popular science Green Arrow, the two shot at each other for 10 minutes across the screen.
Popular science for Cyclops Superman... No, what are you doing, native of the motherland?
Over the years, Depp has had many identities.
He's Iron Man and Batman's best friend, the behind-the-scenes mentor of the Justice League, and a man S.H.I.E.L.D. would never dare to climb.
He is the eternal white moonlight in the Joker's heart, the love of Catwoman's life, and Storm's best brother Depp.
And... a nightmare where everyone in Arkham Asylum is silent.
(Not Long Aotian, the system can't speak)
