Mercureon (Steel/Poison)
#??? - On rare occasion, an Eevee can be affected by more than one environmental factor, and reacts to grow into a new, rare evolution. Eevee who wonder into polluted industrial zones or environments tainted by heavy metal runoff may evolve into the Steel/Poison-type Mercureon. Their bodies consist of a highly reflective, viscous liquid metal that ripples and drips with every movement. In spite of their fluid composition, these Pokémon are deceptively dense and incredibly resilient. They can momentarily liquefy parts of their bodies to slip through narrow gaps, evade incoming attacks, or reshape their limbs into bladed or spiked appendages for quick, powerful strikes. Contact with Mercureon's metallic hide leaves behind a toxic, gleaming residue that weakens and poisons foes, making physical engagement a dangerous gamble. Despite their hazardous nature, these Eeveelutions have carefree and excitable personalities and are not prone to violence; however, their curiosity and affectionate demeanor can be dangerous, as they sometimes forget the risk their bodies pose to those around them. Responsible Trainers must ensure their Mercureon is well-trained and responsive to commands, especially in social situations. To encourage this unique evolution, Trainers may have their Eevee hold a Toxic Ingot while engaging in battles against Poison-type Pokémon.
