Uraneon

Uraneon are the steel-type eeveelution in Dimension B. They are described as having a torso, leg, and tail made out of metal plating and a small window emitting a yellowish-green glow in their sternum.

When agitated, steam can erupt between the plates of metal, and when heavily damaged or dying, the "uranium" core can undergo a meltdown, poisoning all life within a certain radius.

An eevee can become a uraneon after coming in contact with a strange stone from space; the same stone that formed into the two Deoxys. Due to this, uraneon are especially rare and share a special bond with the Deoxys.

Trivia:
 * Uraneon were created by Christopher LeGrand, as a tribute to Pokémon Uranium, the fan-made game that was shut down by Nintendo.
