==Summary==
170,000-Year Cicada Nymph (17万年ゼミ幼虫, 17 Man-nen Zemi Yōchū) is a large Mysterious Being that attacked Z-City at some point during Saitama's training years.
The Cicada Nymph is a massive cicada that has the face of a child located at the center of its head, between its eyes.
During Saitama's training years, the Cicada Nymph attacked Z-City and defeated two C-Class heroes Grad School Graduate, Red Muffler, and the B-Class hero Darkness Blade with ease while the rest of the population barricaded itself within Shelter Nr. 7. Sometime later two unnamed A-Class heroes tried to fight it but were also defeated causing the Hero Association to declare Cicada Nymph as a Demon level threat. They then decide to send one of their newly built subjugation squads to finish it off. Saitama, while running around in search of a bathroom, runs into the Nymph who suddenly attacks him, however, Saitama swiftly defeats it. Years later, Saitama encounters the 170,000-Year Cicada Adult on top of a building, and presumably dispatches it with the same amount of ease as its Nymph counterpart.
