Mayuri Kurotsuchi
Appearance: His mask seemed to scare people. He considered this an interesting side-effect.
Persona: The archetypical mad scientist enjoyed laughing at people who thought they had gotten one up on him.
Power: Having never been satisfied with his natural strength, Mayuri decided to go for unnatural.
Love: Love was something to be dissected, or recorded, but not experienced.
Habits: Looking down on everyone as test subjects made him very few – read no – friends.
Food: He no longer needed to eat, instead taking nutrients via a regeneration bath he spent every night in.
Hates: If perfection was a goal, success was not an option.
Time: He was always on time, right to the second. It was eerie.
