170,000-Year-Old Cicada Adult (17万年ゼミ成虫, Jūnana Man-nen Zemi Seichū, Viz: 170,000-Year-Old Cicada Imago) was a large Mysterious Being that attacked Z-City at some point during Saitama's training years. It was presumably killed by Saitama.[2]


The Cicada Adult was an extremely massive cicada-like creature, easily able to cast a large shadow over a city. Located at the center of its head was a humanoid face.

170,000-Year-Old Cicada Adult attacks Z-City damaging many buildings. Saitama then appears before it and declares with a smile that summer has arrived.

Abilities and Powers[]

Since it was the grown-up version of the 170,000-Year-Old Cicada Larva, it was presumably much more powerful. Even S-Class heroes might have had difficulty dealing against it due to its resistant shell and its ability to fly.[1]

Physical Abilities[]

Enhanced Strength: Due to its enormous size, 170,000-Year-Old Cicada Adult possessed great strength. Even 170,000-Year-Old Cicada Larva, a smaller and weaker version of it, had enough strength to defeat two A-Class heroes and easily smash through buildings.

Enhanced Durability: 170,000-Year-Old Cicada Adult possessed a resistant shell.[1] Even 170,000-Year-Old Cicada Larva, a smaller and weaker version of it, was durable enough to easily smash through buildings without visible damage.

Flight: The Cicada Adult's wings allowed it to fly.
