Korosensei "Assassination Classroom"

APPEARANCE: Korosensei has the appearance of a yellow octopus who is about three meters tall and possessed a large, bulbous head with a large smile that rarely breaks or moves, and small, beady eyes. He uses two tentacles as arms, each having two feelers as fingers, and utilized the rest of seemingly jelly-like limbs - his tentacles - to walk. Korosensei has a pair of hidden nostrils, which make him appear to have four eyes if detected. Due to his constant grinning, he changes his color to express his emotions. Korosensei wears a black academic dress, a small black squarish mortarboard cap with a yellow tassel and a large black tie with a yellow crescent-shaped moon on it, a gift from Aguri Yukimura. Alien Male being is 3m (9'8ft) tall.

PERSONALITY/ABILITIES: It was revealed that he was raised in an environment "where everybody could easily betray one another to the point that one could only trust oneself". Through these hardships, he decided to become an assassin to survive. Despite gaining an apprentice, he only saw him as a tool for his goals, which drove the latter to finally betray his master. However, after meeting Aguri Yukimura, he finally knew what compassion really was--becoming much more kind and compassionate. According to Aguri, if he was born in a peaceful country, he would be "a little lecherous, smart, klutzy, kind of stingy and stubborn" and he would smile because he is genuinely a kind person. This prediction happens to reflect his personality; which became forefront after he answered the tentacles. When first introduced, Korosensei was an upbeat individual who demanded absurd and seemingly mundane requests despite claiming he would be the cause of the planet's destruction in a year. He also rather kind to others in general and could switch from silly and childish to serious on the fly. Korosensei also is unintentionally petty at others at times and loved gossip, both traits heavily noted throug. Korosensei deeply cared for his students' emotional and physical well-being and would lose his temper whenever any of them were put in danger, even by one another. One of Korosensei's attributes that he able to connect to each student individually, being an objective, empathetic, and observant person who will do almost anything to help his students. This why all the students respect him even though he would blow up the Earth in a year. Taking care of each student's needs, Korosensei would sometimes be piqued by a student's current problems or interests and would try his best to guide the student along or solve it for them. Korosensei loved sweets almost to extreme cases, and was also shown to be a very perverted, a trait he shares with his student Taiga Okajima and Itona Horibe. This characteristic was revealed to be the side effect of the experimentation with anti-matter tentacles which made him unable to hide his true feelings. Korosensei can change his skin into any color, utilized for expressing emotions as well as disguise and camouflage. The standard trait of an antimatter organism, the mucus of Korosensei has varied uses for support purposes, such as waterproofing, cleansing, adhesive and the replacement of tears. Korosensei is immune to toxic substances that would definitely kill an ordinary human. Although, such substances do affect him, such as by transforming his head. After he drank the 4th poison made by Manami Okuda, Korosensei developed an ability to control his fluidity where he can morph into a mass of mercury-like slime. In cost of his massive body and tentacles, Korosensei can fit through any space while retaining most of his abilities. Another trump card never used until the Okinawa trip, Korosensei can compress his body into a small sphere, not much larger than a baseball, and the remaining energy from the transformation hardens as a crystallized membrane around his shrunken spherical body. As long as he is in this form, he is completely impervious to harm; by his own admission, even a nuclear warhead wouldn’t be strong enough to even scratch him. After twenty-four hours, the external shell liquefies and he will slowly absorb energy over a period of time until he fully regenerates and returns to his usual form. The only drawback to this trump card is that in the span of the full day, he is rendered completely immobile and is susceptible to being carried around. The only mechanism that could potentially break through this form is the Spear of Heaven. An ability developed from the Absolute Defense. Korosensei can channel a portion of his inner energy to his tentacles in order to discharge a laser blast. By compressing the tips of his tentacles, Korosensei can create massive explosive shockwaves. This technique was used during Itona Horibe and Shiro's final combined attempt to kill Korosensei. A once-a-month occurrence, Korosensei can shed his skin and use it as a protective membrane either on himself or another individual, protecting them from being hurt even from military-grade explosives. Afterwards, his reaction speed may temporarily be reduced, but he can still be fast enough to dodge attacks from the class. If one or more of his tentacles are maimed, Korosensei can regenerate the severed limb. However, this weakens his stamina. Korosensei's sensory perceptions are paramount and can detect even the most minuscule of changes in temperature, light, sound and smell. Despite having no visible ears or nose, Korosensei has proven to be able to hear things no normal human can pick up on, as well as detect the most minor of aromas, which aided him greatly in evading the assassination attempts of Class 3-E. Korosensei is especially talented in identifying people by their smell, as well as certain materials (such as explosives and poisons). His eyes are also quite keen, and can keep track of objects going thousands of miles per hour without difficulty, as well as detect the slightest of movements that occur quicker than the blink of an eye. Korosensei can digest anything aside Anti-Sensei weapons, as his teeth can crush any hard materials. Whether he eats something or it enters his body, he can either melt the food first, then eject it, or it will just be digested. Although it is not guaranteed that Korosensei will receive no irregularities from what he has eaten, it usually has no tactical disadvantages if it is not a weakness for him. Korosensei can travel up to the speed of Mach 20. His normally soft and jelly-like head hardens under immense pressure as a process known as the dilatancy phenomenon, which presumably lowers his wind resistance, allowing him to reach inhuman speeds. The only known objects to surpass this are the reusable space shuttle and the transformed Reaper. As the original Reaper, Korosensei was considered the world's best assassin prior to being betrayed by his disciple. As a result, Korosensei can combat nearly every assassination attempt utilized by both the Class 3-E students and professional assassins, showing to be extremely observant and stealthy at planning and execution. Even before Korosensei gained his powers, he possesses a gifted mind which allows him to learn and understand complex knowledge in a matter of minutes. Since gaining his speed, Korosensei has become hypercognitive and can process information thousands of times faster than the average human being. His greatest feats appear to be coming up with inventions leaps and bounds above contemporary science in a matter of days. Korosensei able to create a chemical granted him his Liquefaction ability. Korosensei able to upgrade Ritsu, designing and implementing approximately 985 modifications and upgrades within less than a single day. He also upgraded her AI to grant her some form of autonomy and sentience. With his immense intelligence, Korosensei was able to single-handedly teach multiple academic subjects and achieve impressive results from Class 3-E. His incredible mentality combined with his speed also allow him to multitask on up to dozens of jobs at a time, all of which seemingly being done simultaneously (including providing individual teaching to every student of Class 3-E simultaneously, focusing on the subject each of them needs to study most and even changing his headband as he goes). Korosensei is able to store all that he has learned and use them to his advantage, which led to him being the most prolific assassin in the world prior to his capture. In order to become a competent educator to Class 3-E, he has memorized all of the text books in Japan so as to be able to coach his students where their weaknesses lie. After he was unable to save Aguri Yukimura from her fatal injury, Korosensei began learning about surgery methods, which he first demonstrated on Azusa to remove her brain tumor without damaging her. He later uses his knowledge to heal and revive Kaede Kayano from receiving the same injury as Aguri.
