Trainneon – The Locomotive Pokémon Eeveelution inspired by Thomas the Tank Engine Type: Steel Pokédex Entry: Trainneon is a highly dependable Pokémon that runs on tracks of pure determination. It emits steam from its funnels when excited, and its cheerful whistle boosts the morale of nearby Pokémon. Appearance: Trainneon has a sleek blue, metallic body with riveted steel plating resembling train parts. Its legs resemble train wheels with soft, rubbery traction. It has a small smokestack on its back that puffs out gentle steam when happy. Its face bears the unmistakable wide-eyed expression of Thomas, but in a more stylized Pokémon form—cute, expressive, and just a touch mechanical. A red trim lines its body, and it has a small train coupling tail. Abilities: Steam Charge (Hidden Ability): Powers up Trainneon's Speed and Attack when hit by a Fire- or Electric-type move. Sturdy: Prevents one-hit KOs. Motor Drive (Dream Ability): Boosts Speed when hit by an Electric-type move. Signature Move – Whistle Burst: Type: Steel | Power: 70 | Accuracy: 100 Trainneon lets out a powerful steam whistle that confuses the opponent and has a 30% chance to flinch. Evolution Method: Eevee evolves into Trainneon when leveled up near a Steam Generator (a special location with railway elements) while holding a Steel Coat. See more
