Ability          Quote “Turns the ground into Electric Terrain when the Pokémon enters a battle. The futuristic engine within the Pokémon also boosts its Sp. Atk stat on Electric Terrain.” — Flavor text[src]     C Hadron Engine   [Edit]   [Talk]

Hadron Engine^{(JPJapanese: ハドロンエンジン)} is a Pokémon ability introduced in the ninth generation. It is the signature Ability of Miraidon.

Description

Hadron Engine creates the effect of the move Electric Terrain on the battlefield as soon as a Pokémon with Hadron Engine enters the battle. The Electric Terrain lasts only for five turns. This can be extended to eight turns if the Pokémon is holding a Terrain Extender.

Hadron Engine also boosts the Pokémon's Special Attack stat by roughly 33% (or more precisely, by a factor of 5461/4096) on Electric Terrain. This boost will occur even if the Pokémon is not grounded. Skill Swap fails if either Pokémon has Hadron Engine.
