I am Invincible; Literally [One Punch Man in Marvel]

One Punch. That's all it takes for me to beat them. It doesn't matter how 'Strong' and 'Angry' they are.... It doesn't matter how cool their supposed 'Weapons' or 'Shields' are supposed to be.... It doesn't matter even if they are considered 'Gods' in other people's eyes.... In the end it always comes down to a single punch. I always wanted to be strong.... Strong enough to defeat my opponent in just One Punch. Finally, I am fully capable of doing so.... But I feel bored. I wanted to be strong didn't I? Then why does my heart feel so empty? ~ ~ ~ This is going to be my second time writing a story, with my first one being a story which I started writing not even a month ago....soooooo you can say that I am pretty much a novice in writing. I know there will be grammatical errors and plot holes but I still tried my best. I just hope you guys like this. And the cover is not mine.... [Discord- https://discord.gg/rJXMJmuY]
