Geryuganshoop

Shaped much like an octopus, the creature has neither arms nor legs nor a proper trunk, just a mass of tentacles hanging from its neck. Two eyes and a mouth sit on an oval head. Beneath a transparent outer layer its flesh is deep blue, and that covering blooms into rainbow hues whenever it goes into combat.

Fiercely loyal, Geryuganshoop will fling itself into danger to guard Boros and relays orders to the crew from a control room aboard the vessel. It is coolly methodical by default, yet its composure cracks the instant the ship or its personnel face a threat. Vanity is its great flaw: convinced that no psychic anywhere surpasses it, the alien wildly overestimates its own might and takes on an intruder it has no business facing without help.

Ranked a Dragon-level threat, Geryuganshoop stands among the invasion's strongest, named beside Groribas and Melzargard. Its psychokinesis is staggering, able to raise and hurl matter with crushing force, and it can even scrub away the friction between an object and the air so that flung stones travel near light speed without burning up, a finesse said to top Tatsumaki's raw output. In battle it turns the surroundings into ammunition, pelting enemies with sped-up debris through moves such as the Telekinetic Shower of Rubble, while the anime grants it a crushing Telekinetic Gravitational Wave. Telepathy carries its voice into the minds of allies and enemies alike, and it even tries to coax Saitama off the ship peacefully. It withstands being pinned beneath a huge door, yet none of that matters: after a hail of rubble leaves Saitama unmarked, the hero flicks one small stone that cleaves the alien's head in two.
