Summary

  • Quick growth characters in anime evolve faster than others in their stories, becoming tremendously strong at an abnormal pace.
  • Characters like Saitama, Ragna, and Jin-Woo rapidly gain immense power within their respective shows, altering their strength levels significantly.
  • Unique circumstances such as extreme training, cheat systems, mentor passes, and past inheritance contribute to the swift and exceptional growth of characters like Jin-Woo, Midoriya, and Gojo.

Characters with quick growth often appear in anime. Their journey to becoming overpowered or incredibly strong is shortened to propel the story’s plot. These characters aren’t always the main characters or the heroes of the story, but they attain a massive increase in strength faster than other characters and are usually considered abnormal.

For three years, Saitama trained every day doing 100 push-ups, 100 sit-ups, 100 squats, and a 10-kilometer (6.2-mile) run till he lost all his hair and became bald. He attained his ridiculous strength in half the time, but the workout to the level-up didn’t match; he had become the powerhouse of his show, capable of taking down any opponent with just one punch.

Although he still hasn’t been recognized, Saitama has achieved way more than any other hero in the One Punch Man series. This bald hero has proven some of his capabilities, exhibiting his speed, durability, and destructiveness with his fist after being kicked from Earth to the Moon, jumping from the Moon back to Earth, and overpowering an attack that would destroy the world with one “serious punch.”
