Nett from The Under is the genius of the Kids Grid. His home and place of operation has a large, rotating antenna dish on top. Nett is Megg's older brother. His name is based on "network," as he runs the Kids Grid computer network.
Nett's job becomes to decipher a Data Rom containing a list of Shadow Pokémon that have been made, and to keep Wes updated on his findings via P★DA. Nett also relays sightings of Shadow Pokémon from people visiting from Pyrite Town.
When Wes travels to the Deep Colosseum, it's up to Nett to keep him informed about the Deep King and his Pokémon, including the Deep King's Shadow Shuckle. He informs Wes when the Deep king enters the knockout tournament, and implores the Trainer to enter and show up the king.
