Nicky Town (ニッキー タウン, Nikkii Taun) is a town on Planet Earth.
Nicky Town appeared during the Imperfect Cell Saga. It was one of the various towns that Imperfect Cell ransacked. Several of the residents were absorbed by Imperfect Cell, including a gunman and his family and many people in a restaurant. Shortly before he had arrived at Nicky Town, Imperfect Cell had confronted a football team (the Battle Ball Team) and absorbed all of them.
