1. Saitama

Saitama is our number 1 favorite character for the obvious reasons. That of course being his absurd strength and hilarious art design.

Saitama is first shown displaying that he's "just a hero for fun" and his immense power by completely eviscerating a villain called Vaccine Man (whom was portrayed by Christopher Sabat).

Throughout the series, he is shown eliminating each of his opponents immediately and without a drop of sweat or effort. Some of these opponents for example are Super Custom YO649Z Mk. II, Deep Sea King, Marugori, Mosquito Girl and Beast King. Saitama also suffers from depression from the result of his awesome power. No one can challenge him or give him the thrill of fighting anymore because his opponents die immediately, like i stated above. How he got his power wasn't by any otherworldly magic or or race genetics like a Saiyan's. Saitama got his power by doing "100 PUSH UPS, 100 SIT UPS, 100 SQUATS AND A 10KM RUN EVERY SINGLE DAY", and after a year and a half his hair started fall out and he noticed his power started to increase as well as his enemies died to one punch. And that is why he makes our number 1.
