Destrochloridium

Destrochloridium is a small parasitic creature whose true body is roughly the size of a human hand.

Despite his tiny stature, he is capable of lethal infiltration operations and successful assassinations.

He invades the Hero Association Headquarters by parasitizing one of its staff members.

Using this stolen body, he manages to get inside the building and shoot and kill one of the Association’s executives.

Destrochloridium is a parasitic-type monster, able to take control of human hosts.

Once attached to a host, he can freely manipulate their body and use weapons as if he were a normal human.

His body is equipped with antenna drills that boast steel-like durability and piercing power.

These drills are intended to penetrate flesh and allow him to latch onto new hosts.

Despite his Disaster Level Tiger classification, which marks him as dangerous to ordinary people, his abilities are limited against powerful heroes.

His offensive power is effective against unprepared humans but not against high-tier fighters.

Destrochloridium secretly parasitizes a staff member of the Hero Association.

Through this disguise, he successfully infiltrates the Hero Association Headquarters.

Once inside, he takes advantage of his position and assassinates one of the Association’s executives by shooting them.

This attack demonstrates the Monster Association’s strategy of internal sabotage and surprise strikes.

However, the parasitized staff member is eventually defeated by Chougoukin Kurobikari (Superalloy Darkshine).

When his host is taken out, Destrochloridium is forced to abandon the body and search for a new one on the spot.

Seeing Superalloy Darkshine nearby, he attempts to parasitize him as a new, stronger host.

He uses his steel-hard antenna drills and tries to pierce Darkshine’s body to latch on.

Even at full effort, Destrochloridium’s antenna drills fail to leave so much as a scratch on Superalloy Darkshine’s body.

Darkshine’s superhuman physique completely negates the parasite’s primary method of attack.

Realizing that he cannot penetrate this “perfect steel body,” Destrochloridium is rendered helpless.

Superalloy Darkshine then casually crushes the tiny monster to death with his hand, ending the threat instantly.

Although his personality is not deeply explored, Destrochloridium displays traits typical of parasitic monsters: opportunistic, sneaky, and ruthless.

He prefers ambush tactics and host manipulation over direct combat, targeting important figures from the shadows.

His attempt to jump from a defeated host to a far stronger one shows both ambition and desperation.

This overconfidence, combined with underestimating a high-level hero, leads directly to his demise.
