Aquaman!

 Watery world

One day there was a man with gills. He did not have any money to take care of himself. So the president kicked him out of his house but after he cried for half an hour he had an idea? Because he had gills he ran into the ocean and made a house in 20 seconds because he also had special powers. 26 years later there was a giant beast attacking Atlantis, he had grown four million times his old powers so he rose from the ground to save his city from the sea beast.

When he reached the top the man saw how massive it was. It was 40 times the size of godzilla, he was terrified but it was not going to stop him. Bang he attacked, crash, boom, bang, snap, scrap, scream, boom the man demolished him and he protected his city from many many more villains.

That's how he got his name aquaman!
