Anti-Sensei Weapons



The Anti-Sensei Weapons are special weaponry developed for the assassination of Korosensei.

Overview
Anti-Sensei weapons are made with a special rubber-like material that are only effective against Antimatter Tentacle-based lifeforms, such as Korosensei, thus making them harmless to ordinary humans. They have been shown in the form of BB bullets, grenades, knives, nets, cages, and even clothing.

Tentacle lifeforms are immune to ordinary weapons, in fact, metal weapons and ammunition will actually melt if they pass through the body of a tentacle-based lifeform. Anti-Sensei weapons on the other hand will cause the cellular tissue of a tentacle-based lifeform to disintegrate upon mere contact.

Anti-Sensei Bullets
The Anti-Sensei bullets are small, round BB gun pellets. They are fired from pressurized air guns which take the appearances of real guns.

They can be used in a variety of ways, such being embed in baseball, a method of delivery that is much quieter than the air gun. They can be scattered across the floor in hopes that the intended target will step on them, causing their tentacle feet to disintegrate.

These pellets were once loaded into a fragmentation grenade by Terasaka in his first attempt to kill Korosensei.

Anti-Sensei Knives
The Anti-Sensei Knives take the form of green military combat knives. They have the strength and bendability of ordinary rubber.

The knives can be used in a variety of ways. They can be cut up and pasted/taped to something in hopes that the target will touch them, such as attaching the pieces to ones hand and then offering the target a handshake. The knives can also be used as spikes in a pitfall trap.

Anti-Sensei Clothing
The Anti-Sensei material can be made into fabric which can be sewed into clothing. Anti-Sensei Clothing functions like a protective suit of armor that will disintegrate the flesh of an tentacle-based lifeform that touches it.

Spear of Heaven
A colossal Anti-Sensei satellite weapon dubbed the "Spear of Heaven". This special weapon works by shooting a silent beam of light specifically designed to vaporize tentacle-based creatures, specifically Korosensei. At full power, the laser can cover the entire zenith of the old campus hill.

Shield of Earth
A large energy dome designed to destroy anything made of the antimatter tentacles, used to prevent Korosensei from escaping the range of the Spear of Heaven. The Reaper, augmented with the tentacles, was killed when he was sent into the barrier. Yanagisawa, also augmented with tentacles, was rendered permanently disabled after being propelled toward the barrier.
