Shelly is a character appearing in Pokémon Generations.
In The Cavern, Shelly along with a few Team Aqua grunts infiltrated the Weather Research Institute. While there, she researched Primal Kyogre and realized the consequences of awakening Primal Kyogre. Shelly then attempted to stop Team Aqua leader Archie from using the Blue Orb on Kyogre, warning him that Primal Kyogre would sink everything and bring despair to the land. But Archie ignored Shelly's warning and goes along with awakening Primal Kyogre. Shelly was later seen in the submarine Explorer 1 as Primal Kyogre sets its sight on Team Aqua.
