Marvel: A Demon-Hunting Adventure with Spider-Man!

After transmigrating into the Marvel universe, by day, I'm a Spider-Man who isn't much good at killing.

By night, I enter a game and embark on a demon-hunting adventure with my Bruce!

"Go, Bruce! Let's defeat the evil dragon together! Hurry, use your ultimate move!"

Iron Man: "You're beating up my cars in my underground garage. Even if you're mentally ill, I'll sue you into bankruptcy."

"Bruce, you're hurt. Let me heal you."

Nick Fury: "Please wipe that pile of crap off my head. Also, you're the one who needs treatment!"

"Bruce, you're my best friend. We'll be together forever, until we destroy the very last demon."

Gwen: "Get off my bed! Right! Now!"

"Bruce, let's show those evil villains the bond we share!"

As an alien army invades, Mark stands atop a spaceship, shouting about their bond. An endless tide of holy light annihilates everything.

"Tell me, who exactly is Bruce?" a utterly defeated Thanos asks, unwilling to accept his loss.

The Avengers: "We have no idea! He just keeps charging at us, yelling about bonds and friendship and stuff, and then he wipes you guys out."

The next second, Mark cheers, "Great! All the demons have been destroyed!

"Wait, Bruce. You know dogs can't speak like humans.

"So, Bruce, you're the last demon, aren't you?"

The instant Mark sets his sights on the Avengers, they finally understand.

Bruce is actually a dog.
