Giant Crow (巨大黒烏, Kyodai Kokū) was a Mysterious Being sighted flying above M-City. It was killed by Saitama.[3]


Giant Crow lived up to its name with its main body being larger than an apartment tower. Its feathers were black while the eyes glowed red. It was equipped with large sharp teeth in its beak.


Hero Association SagaEdit

King ArcEdit


The Giant Crow's corpse

The Giant Crow first appears in M-City, causing an emergency evacuation, but contradictory also warning the inhabitants not to step out of their house. It crashes into King's Apartment but is stopped by Saitama. After letting out a loud screech, its head is obliterated by Saitama. It was later seen laying headless on the ground  with its wings spread out.[4]

Abilities and PowersEdit

As a Demon-level mysterious being, Giant Crow was naturally a rather powerful monster. Although its abilities weren't shown due to how quickly it was defeated, it was shown to have many unique abilities such as poisonous fangs and absorbing its enemies' powers, which is possibly a reason why it went after King in the first place, though a bonus chapter later reveals that its actual target was Saitama's shiny bald head. However, as expected, it was effortlessly killed by Saitama. Additionally, it has been stated by ONE that Puri-Puri Prisoner, the lowest ranking S-Class hero, could have defeated the Giant Crow.

Physical AbilitiesEdit

Flight: Giant Crow's feathered wings allowed it to fly.

Enhanced Strength: The creature was able to smash into a building with little to no injury.

Fangs (牙, Kiba): It had poisonous fangs.[1]

Digestive Assimilation: It could absorb the enemy's strength by eating them.[1]

Fighting StyleEdit

Hand-to-Hand Combatant: Giant Crow relies on close-quarters engagements to fight.

  • Fang Beak (牙嘴, Kiba kuchibashi): Giant Crow dives directly towards a target and attacks it with its beak.[1]
