Geryuganshoop

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

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

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

In regard to its prowess in battle, Geryuganshoop was somewhat arrogant and believed that there was no other psychic in the entire universe that surpassed it in skill. As such, it thought of itself as much more powerful than it truly was; attempting to handle even an intruder that has wiped out a large portion of the ship and its workers on his own.

Alien Conquerors Arc
Geryuganshoop is first seen monitoring the damage done to the ship. After Boros approaches it, 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 that Melzargard was tied up on the ground.

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. It contacts the gunner afterward, 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.

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 its attacks. It sends a large amount of rubble at Saitama, believing itself 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 do it. He then demonstrates by throwing a small rock at Geryuganshoop's head, splitting it in half.

Abilities and Powers
Given its status as a Dragon-level mysterious being, Geryuganshoop was a very mighty foe with vast psychic powers. Geryuganshoop was 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 its confidence in its skills which, while formidable, were not nearly enough to defeat the hero.

Physical Abilities
Enhanced Durability: Geryuganshoop was able to remain undamaged from being buried under a large door.

Supernatural Abilites
Psychokinesis: Geryuganshoop possessed the ability to levitate and hurl matter using its mind. It was an immensely powerful psychic with a very high psychic output. Geryuganshoop was able to eliminate the friction between objects and air, a feat above the level of even Tatsumaki. As a result, the rocks launched by Geryuganshoop would fly at sub-light speed without being evaporated.

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 used telepathy to communicate with its comrades and underlings.

Fighting Style
Master Psychic Combatant: Geryuganshoop used its environment to its advantage, launching rocks at its opponents with its psychokinesis. It wielded the ability to eliminate friction between the air and the objects it threw, which allowed it to throw objects at speeds approaching the speed of light without unintended consequences. It also claimed to be the top psychic combatant in the universe.
 * Telekinetic Shower of Rubble (念動流石波, Nen-dō Sasuga Nami): Geryuganshoop accelerates rubble and throws it at a target.


 * Telekinetic Gravitational Wave: (超動念動重力波, Chō-dō nendō jūryoku ha) Geryuganshoop drastically increases the forces of gravity around a specific point. This move only appears in the anime.

Trivia

 * 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.
 * 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 as it does, her output would be too powerful, the temperature would increase due to friction and pressure, and would evaporate the rocks in an instant. Geryuganshoop's psychokinesis can eliminate the friction between objects and air so that the rocks can 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.
 * Murata states that if Melzargard, Groribas, and Geryuganshoop decided to work together to fight against Orochi, even with preparation, they would have almost no chance of winning.
 * In the 2017 One Punch Man Halloween cover, Geryuganshoop is depicted wearing a bedsheet in reference to the typical bedsheet ghost.
