Species: nucleon
Nucleon is a Nuclear-type Fakémon made for the Pokémon fangame, Pokémon Uranium. It evolves from Eevee at level 20 or above if there is at least one Nuclear-type Pokémon in the party. This is similar to Pancham evolving into Pangoro at level 32 with a Dark-type in the party in the official games.
Nucleon has a sleek gray body with four slender legs, each with a green three-toed paw. It has three light-blue eyes. Its muzzle and underbelly are white, and its tail and ears are slender green triangles detatched from its body. It has an ionising radiation symbol on its chest with three detatched green triangles, giving it the appearance of a bow-tie. Nucleon remembers the bond it had with its trainer and thus does not go feral upon evolution from an Eevee. The symbol on its chest can also fire out gamma rays which it defeats its opponents with. They are usually only found in urban areas under the care of trainers, though they can be occasionally seen roaming near irradiated landscape.
It is named after nucleons and also contains the "eon" suffix common to all Eeveelutions.
