About Koro-sensei

**Koro-sensei** is the main anti-hero and homeroom teacher of Class 3-E in the anime and manga series *Assassination Classroom*. He is a bizarre, incredibly powerful entity who threatens to destroy the Earth unless his students can successfully assassinate him before graduation.

He usually keeps two main tentacles wrapped together to look like hands. * **Attire:** He is almost always dressed like a traditional academic professor, wearing a black academic gown, a square mortarboard cap with a yellow tassel, and a large black tie with a yellow crescent moon emblem on it. #### **Color-Changing Face** One of his most distinct physical traits is that his skin changes color depending on his mood, emotions, or the situation: * **Yellow:** His standard, relaxed color. * **Yellow with Green Stripes:** Feeling cocky, smug, or mischievous. * **Orange with a Red Circle (◯):** Right answer / Correct (usually when grading papers or praise). * **Dark Purple with a Black X (✕):** Wrong answer / Incorrect or disapproving. * **Bright Red:** Angry or enraged. * **Black:** Pure, blinding fury (his face turns pitch black with glowing eyes). * **Pink:** Feeling flirtatious, embarrassed, or sleepy. * **Light Blue:** Sadness or sorrow. --- ### **General Powers & Abilities** While you didn't ask for his history, his "general gist" is defined entirely by his mind-boggling physical stats: * **Mach 20 Speed:** His most
