American Comics: Tom Cat Helps Me Sweep Across the Universe!

The protagonist is thrown into Marvel as a prisoner from the start, but unexpectedly binds himself to Tom Cat for trading.

He trades cheese for laser guns, beats the Black Fat Lady into submission with gold bars, then simply takes Tom as his pet.

Next, he recruits Hydra, establishes the Hellfire Club, and brings the White Queen and the Maximoff sisters under his command.

Magneto comes looking for trouble? Blackheart melts metal with a single finger and makes him kneel to apologize.

The Elven Queen offers him the One Ring prophecy book of her own accord, and he repays her by granting her a knight's breathing technique.

He's absorbing fairy power in seclusion when the Phoenix and Chaos go berserk? Tom slaps all three forces flat.

The Battle of New York begins. Thanos emerges from his cocoon at the Celestial level, and the protagonist sweeps through the Chitauri Army with Tom.

So what if nuclear bombs lay waste to everything? Tom kicks the bombs around like balls, while the protagonist crushes the Celestials with a flick of his hand.

In the final battle, the protagonist rides Tom through the multiverse, trampling primordial gods underfoot.

All of Marvel is the protagonist's personal playground, and he can do whatever he wants.
