I Only Need One Punch!

A 58-year-old man who had grown up in the mountains and practiced martial arts for decades suddenly obtained a System that let him transmigrate across the heavens. From then on, he set out to fight his way through every world.

The Avengers world. Thanos: "Hahaha! The Milky Way, here I come! Once I collect the Stones, one snap will finish you all!"

Chen Fan: "What kind of demon or monster is this?! Come out! This old man only needs one punch. Let's see if you can take it!"

Sensing the boundless aura emanating from Earth, Thanos quietly withdrew from the Milky Way...

The One-Punch Man world. Aliens invade, the supermarket in the neighboring city is having a huge sale, and Saitama is nowhere to be found. What now?!

Boros: "Hahaha! How could a puny planet like Earth possibly have anyone who can stand against me?! What utter nonsense!"

Chen Fan: "You ugly, creepy-looking thing! Take this old man's punch!"

Boros died at the age of ten thousand, believing to his dying day that all Earthlings were old men.
