Render korosensei

Absolute Defence


Pre-full transform

The fact that I'm targetted by everyone... Is proof that I'm powerful, after all.


Korosensei is the homeroom teacher for Class 3-E of Kunugigaoka Junior High School, and the central character and main antihero of Assassination Classroom. Korosensei claimed to be responsible for creating the permanent crescent moon and said that he plans to destroy the earth after "teaching" Class 3-E for a year. Prior to being a teacher he was the master assassin known as the "God of Death".

Weaknesses: None notable as a human, but likely overconfidence (Which is why he was captured). As Koro-sensei, he has many weaknesses, but not all of them are combat applicable. For a full list, see here.

  1. When he tries to show off, he gets sloppy.
  2. He is quick to panic when placed in a bad situation.
  3. His physical strength is lacking, which is why he focuses on speed.
  4. He is easily distracted by breasts.
  5. His body is incredibly absorbant, especially with water. If he gets wet, his body swells up and he becomes much slower. This is why he won't swim without a protective suit. Extremely high humidity causes a similar effect.
  6. In the time after he either regenerates or sheds his skin, he becomes incredibly weak and much slower.
  7. A certain frequency of light causes him to become more solid and unable to move for several seconds.
  8.  He is weak to heat, suffering from heat exhaustion quickly if exposed to it for too long.
  9. His body goes rigid when bathed in a special beam of light
  10. He is not good at hiding himself.
  11. Regenerating uses up a lot of energy and greatly hampers his combat abilities.
  12. If his heart, hidden underneath his neck tie, is completely destroyed, he will die immediately.
  13. Losing tentacles will cause his speed to decrease dramatically. For example, losing seven tentacles reduces his speed from Mach 20 to just over 400 km/hr. In addition, if all of his tentacles are held down (which a normal person can easily do provided they can catch them), he cannot move.
  14. Once he assumes Absolute Defense Form, he cannot move for 24 hours.
