Ko-Guy

The Grasshopper Curse (バッタのい) was an antagonist in Jujutsu Kaisen. It was a Special Grade Cursed Spirit that was guarding the Curtain located at the B2F entrance to the Shibuya Station.

Appearance
This Cursed Spirit looks like a human-sized anthropomorphic grasshopper with two pairs of arms.

Personality
The Grasshopper Curse is capable of speech, although it is not perfect when it comes to that. This spirit considers itself to be smart, despite not being particularly bright. It seems to value intelligence, believing that the non-smart people are the first to die.

Shibuya Incident Arc
Yuji Itadori encountered the Grasshopper Curse munching on a human corpse, when he entered the Shibuya Station at the B2F entrance. The young Sorcerer asked the Curse about Mahito's whereabouts, to which the Grasshopper responded by answering the question and adding that it's protecting a Curtain here. Yuji took it upon himself to exorcise the Curse in order to get rid of the Curtain. The Grasshopper was initially overpowered, so it tried a surprise attack, but it didn't work and Itadori promptly eliminated the Curse off-screen.

Abilities
Enhanced Strength: Due to being a strong Cursed Spirit, Grasshopper is much stronger compared to a regular human.

Four Arms: The primary advantage of this Curse is its four arms, which it can control freely.

Storng Jaw: The Grasshopper Curse seems to have a strong jaw, as shown when it was eating a human corpse. It also uses its jaw in combat.

Enhanced Vision: The Curse supposedly has better eyes than a human.

Felxible Abdomen: Due to being based on a grasshopper, this Curse may freely control its abdomen. It can also harden the tip and extend it up to three times its normal length.

Jujutsu
High Cursed Energy: The Grasshopper Curse was created because of the negative emotions associated with locust plagues, thus it possesses a great amount of Cursed Energy.

The Grasshopper Curse doesn't seem to possess the ability to use Cursed Techniques.
