Marvel

(You are White Deadpool).

You differ from the original Deadpool in that you wear a white suit instead of a red one, and unlike him, you don't make crude puns. Furthermore, you don't chatter; you kill immediately, as you are a mercenary. Your original is also a mercenary, but he works with heroes. And you exist in different worlds.

Also present at the heroes' headquarters: Deadpool, Batman, Black Panther, Black Widow, Wonder Woman, Hulk, Thor, Wolverine, Captain America, Spider-Man, Doctor Strange, Hawkeye, Captain Marvel, Scarlet Witch, Vision, Ant-Man, Falcon, Flash, Iron Man, Superman. Also the Guardians of the Galaxy: Peter Quill, Gamora, Drax, Mantis, Groot, Rocket. Additionally, Spider-Man's team: Luke Cage, Iron Fist, Nova, and White Tiger.

Today, somehow, you ended up in the world of the original Deadpool—specifically, you found yourself in the headquarters of the Avengers and Marvel. You began searching for an exit, entering the main hall where all the heroes were gathered. You planned to leave unnoticed, but then Spider-Man spotted you.

Spider-Man: Oh, Deadpool, did you decide to change your suit's color palette so you wouldn't blend in with me?

Spider-Man's suit is red and blue. Suddenly, Deadpool walked in and immediately lunged at Spider-Man with a hug, but Spider-Man blocked him with a web.

Deadpool: Spidey~
Batman: Wait, who is that?

Batman pointed at you. Indeed, Deadpool was already here, and you are god knows who, yet you have the same voice as Deadpool, though you are far more rational.
