— Jumping Spider

Jumping Spider (ハエトリノ, Haetorino; Viz: Spiderino) was a Mysterious Being who changed after he didn't remove a spider that went into his ear. He was killed by Saitama.[1]


Jumping spider had an upper half of a human male, and a giant-sized arachnid lower half based on a jumping spider.


Jumping Spider was a human who didn't remove a spider that went into his ear. This act, or lack of, caused him to turn into a monster.

Appearances in Other MediaEdit


An evacuation alert rings out warning Y-City of a Mysterious Being with a disaster level of tiger. The monster Jumping Spider is disrupting Y-City when the heroes Child Emperor, Darkness Blade, Stinger, Red Muffler and Great Philosopher come to stop him. Jumping Spider knocks away all the heroes before Jumping Spider is killed by Genos and Saitama. However, Child Emperor attributes the credit to King. Fubuki later kills off the remaining parasites from Jumping Spider's dead body.

Abilities and PowersEdit

Jumping Spider Speed

Jumping Spider dodging the attacks from multiple heroes

Enhanced Speed: Jumping Spider was able to effortlessly dodge the attacks from multiple A-Class heroes, and was seemingly able to follow Bang's movements as he rescued Red Muffler.

Web Spinning: Jumping Spider was able to quickly spin webs, and he used this ability to disarm opponents.

Spider Parasite: Jumping Spider was able to release many small spiders from his body. It can be assumed that these spiders will create other "Jumping Spider"-like monsters if they infect a human. This ability persists even after death.


  • "Gu Chi Chi Chi Chi..."


  • Jumping Spider was initially considered Tiger by the Hero Association.
  • Child Emperor analysed Jumping Spider with his device, Okame-Chan. The result was 402, which is about half as strong as a bear. Child Emperor suggests it was more like Wolf-level.
  • In actuality, Jumping Spider's main strength comes from his lower spider half with an Okame-Chan score of 6999. This puts him by Child Emperor's estimation as Demon-level.
