Guns, knives and poisons | None notable
Notable Techniques Advanced Nekodamashi: When the opponent's conscious wavelengths reach their peak, when said opponent is in a state of extreme concentration and agitation, even the tiniest stimuli will cause a tremendous shock to their system. Which can be used to temporarily paralyze the target and make them collapse .
Conscious Reading: The human consciousness has wavelengths , looking into the vibration of the target's mind, you can sense their breathrate, line of sight, their facial expression and critical openings in their defenses . The user gets an image in their head, being able to see if their target's face is bright or dark. When they look light, they are off guard, but when they look dark, they are on guard. Using this, the user can read the target's intention and predict their attacks before they can give it off .
Absolute Defense Form: Korosensei forms a translucent sphere that is compressed of high-density crystallized energy. He shrinks his body as small as he can, then uses the surplus energy to form a shield around it. Once in this form, he is truly invulnerable. Water, anti-tentacle bb's, it repels them and everything else . The only official object that was able to penetrate it was the Spear of Heaven .
Energy Blast: An ability developed from the Absolute Defense, he can concentrate and withdraw energy from some of his tentacles to create a powerful blast .
Molting: 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 grenade explosions .
Superhuman Senses: Despite being a smiley face emoji, Korosensei still has his sensory organs . He has a strong enough smell to smell a bomb hidden in a giant pudding , can smell the sent of his students on a mountain in the distance , can smell his students eating chocolate in a forest , and can smell the scent of an assassin in an airport kilometers away . His sight is so good that he can spot a beetle on a tree and see Karasuma and The Reaper's fight many meters away by zooming in his eyes. Finally, his hearing is so good that he can hear and recognize the sound of each of his individual student's footsteps many meters away.
Superhuman Digestion: Korosensei can coat his tongue with his digestive acids , which are strong enough to melt shoes on contact and melt metal bullets .
Water Absorption: Upon contact with water, a tentacle will absorb it like a sponge and swell up, and thus its mobility will be hindered . This can be partially negated if his mucus is used to turn it into a gel .
Mucus: His mucus can do more than just negate his water absorption. It also allows him to fly silently , can stop bullets , and can replace human cells perfectly .Other Standard Tactics:
Weaknesses: None notable | List of all of his noted weaknesses , government made material that can bypass his durability , gets slower when his body absorbs water , loses 20% of his speed per tentacle he loses , his reaction speed slows down when he's psychologically shaken up , isn't good at adapting to changes in the environment , and is completely immobile in his Absolute Defense Form .
Note
↑ Technically, there are a handful of feats of Korosensei that get him above Mach 20. However, canonically Korosensei top speed is stated many times to be Mach 20 and there are anti-feats that support him being just Mach 20. So for the same of argument, I'm siding with what the narrative leans to.
