Ken Sugimori's artwork of Celio.
Celio (Japanese: ニシキ Nishiki) is a Pokémon storage system programmer and good friend of Bill who lives in the Sevii Islands.
Celio runs the Pokémon Net Center on Knot Island in Pokémon FireRed and LeafGreen. He needs the player's help to finish the incomplete Pokémon Network machine. This machine is capable of transferring Pokémon between Kanto and Hoenn. Communication with Hoenn will not function until the Ruby and Sapphire have been collected by the player. To assist with this quest, Celio will give the Rainbow Pass and upgrade the Town Map so it shows the locations of the final four Sevii Islands. If the map had not previously been obtained, he will give the map for Kanto as well.
Celio's name may refer to the acronym for the Corps of Engineers Library Information Online.
