Canon, AU, or OC?: Canon

Universe of Origin: Assassination Classroom

Personality: He is a brilliant teacher, able to teach almost every subject by himself; Math, Science, Writing, you name it. He is very protective of anyone he cares about, and will do whatever he can to ensure their safety. He has an incredibly strong sweet tooth, and will go to great lengths (legally) to satisfy it. He is aware he is incredibly powerful compared to normal humans, as he has been targeted by several world leaders and able to survive every attempt made to kill him. He is also apparently a pervert, as he prefers large breasts.

Abilities/Weapons: 
- Flight: Despite having no wings no any other visible means to do so, he can shoot off into the air and fly.
- Mach 20 speed: This thing is fast. Wicked fast. So fast he will fly alongside and clean a flying fighter jet at the same time, or avoid assassination attempts while trimming that assassin's eyebrows. He can literally fly around the Earth in a mere 20 minutes.
- Keen sense of smell: For some octopus thing with no nose, he has a remarkably powerful sense of smell. He can smell sweets from more than several yards away, or the smell of copper from hidden bullets.
- Colorful face: Korosensei's face changes color according to his mood, although that doesn't stop him from changing the color at will. See [url=http://ansatsukyoshitsu.wikia.com/wiki/Korosensei#Appearance]link[/url] for details.
- Bullet immunity: regular metal bullets do no harm to him, instead simply melting in his body.
- Regeneration: Korosensei can regenerate any damage done to him in a matter of seconds, although doing so apparently takes a toll on him.
- Skin shedding: Korosensei's "ace in the hole". By shedding his skin, he can create a sort of armor to protect himself (and others if he has to), as well as create a decoy to distract an attacker for a few seconds. It can only be used once a month, and takes a toll on him after he has used it.

[hider=Backstory]As a child, Korosensei was born into one of the most vile and corrupt slums. Growing up, he suffered abuse from his family, and watched as corrupt cops ignored the constant number of people who were killed on a daily basis in the slums which he lived in. It was an environment where everyone could easily betray you to the point that you could only trust yourself. Through these hardships, Korosensei immediately developed into a sociopathic killer and began to make a name for himself as the God of Death. Immediately, his talents were shown as he left a tremendous trail of corpses in his wake. He became notorious for breaking through even the most strict security teams to assassinate his targets.

All this changed after assassinating a wealthy buisnessman and father. The man's child witnessed the killing. Immediately, he became enamored with the beauty of the kill and requested that Korosensei train him as an apprentice. Eager for the assassination oppurtunities that an apprentice could give, Korosensei immediately and harshly trained the boy. After several successful jobs, the apprentice turned on the God of Death as he was attempting to escape a prison facility. The apprentice, the current God of Death, sought his master's title and abandoned him just to fuel his ego. Betrayed, Korosensei was captured and thrown into a research labratory run by Shiro. It was there that he met and befriended Aguri Yukimura. However, one day there was an explosion and Aguri became fatally injured. Her final wish to Korosensei was to teach her students (Class E), all the while thinking of what a wonderful teacher he will be.

Right before the start of the series, Korosensei destroyed 70% of the moon, forever leaving it in a crescent shape. Korosensei reveals to the world's leaders that he has decided to destroy the Earth as well the following year during March. He then tells the world leaders that he wants to become the homeroom teacher for Kunugigaoka Junior High School's Class 3-E. The world leaders accept the deal, hoping it will give them a chance to assassinate Korosensei; however, they also added another condition: he would not harm the students.

Later, Korosensei came with Karasuma, who was from the Ministry of Defense, to the front of Class-E and introduced himself. Karasuma explained the situation and demanded the students to assassinate the new homeroom teacher. As an example, he tried to assassinate Korosensei, but Korosensei used his mach 20 speed to dodge Karasuma's strikes, and even meticulously trimmed his eyebrows. After that, Karasuma revealed that the reward for killing him would be 10 billion yen, and Korosensei simply looked down on them while his skin became covered in green stripes. After Karasuma ended his explanation and showed the weapons, Korosensei declared that they should spend the last year in a meaningful fashion.

As the weeks and months passed, the students got better and better at assassination, and transfer students occasionally came in to kill him as well. However, Korosensei stayed as unkillable as ever, always dodging and/or blocking the special Anti-Sensei Weapons designed specifically to kill him. Still, the students do their best to kill him while also obtaining a decent education.[/hider]
