Geryuganshoop (ゲリュガンシュプ, Geryuganshupu) was an alien. It was a general of the Dark Matter Thieves and the right-hand man of Boros.[1] It was killed by Saitama.[2]


Geryuganshoop's body was dark blue covered with translucent skin, which turns rainbow-colored when it is in a fight. It has no arms, legs, or torso, but rather a multitude of tentacle-like appendages connected to its neck, much like an octopus. Its head is oval and has two eyes and a mouth.


Geryuganshoop was loyal to Boros; willing to throw itself in danger to defend him from intruders. At the same time, it recognized his own rank and hands out orders to all members of the Dark Matter Thieves from a control room, namely the various workers on board the ship. It is calculative in most circumstances, but can lose his cool if the ship and those within it are put in danger.

In regard to his prowess in battle, Geryuganshoop is somewhat arrogant and believes that there is not another psychic in the entire universe that surpasses his skill. As such, it thinks of himself as much more powerful than it truly is; attempting to handle even an intruder that has wiped out a large portion of the ship and its workers on his own.


Hero Association SagaEdit

Alien Conquerors ArcEdit

Geryuganshoop is first seen monitoring the damage done to the ship. After Boros approaches him, inquiring what is happening on the ship, it explains the situation and is ordered to send Groribas after Saitama. It explains that Groribas had already been killed and Melzargard was tied up on the ground.[3]

Geryuganshoop contacts Melzargard with the orders to return to the ship and attack the intruder. However, Melzargard is occupied in battle and requests support fire from the ship.[4] It contacts the gunner afterwards while also telepathically contacting Saitama, warning him not to go further into the ship. Saitama blatantly disregards the order and does the opposite, charging into Boros' throne room.[5]

Geryu's head split in half

Geryuganshoop's head is burst open by Saitama's rock-throwing

Geryuganshoop attacks Saitama from behind with a barrage of rubble from the destroyed door, claiming that as the top telekinetic in the universe, no one can survive his attacks. It sends a large amount of rubble at Saitama, believing himself to have won, but is surprised to see Saitama standing unharmed. Saitama remarks that throwing rocks around with telekinesis is a waste of superpowers, since anyone can throw stones. He then demonstrates by throwing a small rock at Geryuganshoop's head, splitting it in half.[6]

Abilities and PowersEdit

Given his status as a Dragon-level mysterious being, Geryuganshoop was a very mighty foe with vast psychic powers. Geryuganshoop had been stated to be one of the most powerful beings in the group of invaders, alongside Groribas and Melzargard. When it fought Saitama, it wasn't scared of him, despite Saitama having defeated Groribas, showing his confidence in victory, which was quickly proven wrong. 

Physical Abilities Edit

Enhanced Endurance: Geryuganshoop was able to remain undamaged from being buried under a large door.[7]

Supernatural AbilitesEdit

Psychokinesis: Geryuganshoop possessed the ability to levitate and hurl matter using his mind. It is an immensely powerful psychic with a very high psychic output. Geryuganshoop can actually eliminate the friction between objects and air, a feat even Tatsumaki cannot do. As a result, the rocks launched by Geryuganshoop will fly at sub-light speed without evaporating the rocks.[8]

Telepathy (テレパシー, Terepashī): Geryuganshoop used telepathy to contact Saitama and tried to stop his rampage through the ship in an attempt to peacefully guide him to an exit. In addition it has used telepathy to communicate with his comrades and underlings.[1]

Fighting StyleEdit

Master Psychic Combatant: Geryuganshoop used his environment to his advantage, launching rocks at his opponents with his psychokinesis. He wields the ability to eliminate friction among the objects he throws, allowing him to throw objects at speeds approaching the speed of light without unintended consequences. It also claims to be the top psychic combatant in the universe.

Telekinetic Shower of Rubble

  • Telekinetic Shower of Rubble (念動流石波, Nen-dō Sasuga Nami): Geryuganshoop builds up a tornado composed of rubble around himself and then accelerates the rubble at a target. [9]
  • Telekinetic Gravitational Wave: (超動念動重力は, Chō dō nen dō jūryoku ha) Geryuganshoop drastically increases the forces of gravity around a specific point. (Anime-only)[10]

  • Murata stated on a stream that he isn't sure if Geryuganshoop can create black holes as it seems too powerful. He won't know for sure without asking ONE.[8]
  • Murata stated that Geryuganshoop's ability to control flying objects should be above Tatsumaki, because it can eliminate the friction between rocks and air. If Tatsumaki throws rocks like it does, her output will be too powerful, the temperature increase due to friction and pressure, and evaporate the rocks in an instant. Geryuganshoop's psychokinesis can eliminate the friction between objects and air, the rocks will fly at sub-light speed. Tatsumaki can throw very large objects, but there's a limit to how fast she can throw them. In Saitama's eyes, however, rocks at sub-light speed are nothing, it's like a bad joke.[8]
  • Murata states that if Melzargard, Groribas and Geryuganshoop work together to fight against Orochi, even with preparation, they have almost no chance of winning.[11]
