Episode 1 - The Strongest Man
This is so ridiculous... a very boring character with a boring backstory and boring motivations defeats some crazy powerful supervillain monsters in one punch...
Episode 2 - The Lone Cyborg
Mosquito queen commands all the mosquitos to get blood for her, and she turns super powerful... some cyborg superhero guy is going after her, and fails to defeat her, then he sees Saitama defeat her easily in one punch... the cyborg Genus then becomes Saitama's apprentice. He babbles on a lot with his backstory until Saitama stops him and tells him to sum it up in 20 words or less...
Then we see the villain who was in charge of that mosquito lady... he sends a bunch of other monsters to try and capture Saitama after seeing how strong he is.
Episode 3 - The Obsessive Scientist
The villain is some old guy who dedicated his life to researching human evolution.. he eventually discovered some way to create evolved humans, and made clones of himself and started running a monster laboratory... the ultimate monster he created was supposed to be unbeatable, and it looked like Saitama was actually worried when this monster turned to his "rampage mode"... but actually he was just worried because he realized what day it was.
