From Bulbapedia, the community-driven Pokémon encyclopedia.
Area 28 (Japanese: エリア２８ Area 28) is an anime-exclusive location in the Unova region. It exists along Route 4 and is notorious for UFO sightings.
Professor Icarus lived there after he quit his job as a professor at a university in order to work on how to manipulate dark matter. It was also where he encountered Elgyem.
- Area 28's name is an obvious spoof of Area 51 which is often the subject of UFO speculation. Its setting is also drastically based on the real world location.
