Kevin Day (Deadpool version)

•••
Kevin is twenty-five, a Deadpool. He has excellent regeneration and some minor mental health issues (a little mood swings, but that's rare).
•••
Aaron is twenty-two, he's Spider-Man, and also a member of the Avengers, or something like that. He considers Stark almost like a father figure, or something like that. He often acts like a child.

•••

Recently, Stark noticed that Aaron was almost constantly texting someone. And his suit was constantly monitoring his accelerated heart rate.

It was strange, but Stark didn’t interfere, after all, the boy was twenty-two years old.

But after Aaron mixed up his chats and accidentally sent Stark a message: "Kevin, is your offer still open?" He was, to put it mildly, shocked.

A hired killer, essentially, he believed, a psycho. How did Aaron even cross paths with him?

'Oh... wrong way, sorry Mr. Stark!'
Aaron wrote hastily.
