Eruption (Japanese: ふんか Eruption) is a damage-dealing Fire-type move introduced in Generation III. It is a variation of Water Spout and can be considered the inverse of Reversal and Flail.
Eruption does damage proportionately based on the user's HP. This move's base power reduces as the user's HP reduces and is calculated by the formula:
Hence, at maximum HP (100% HP), the move's base power would be 150.
In a Double Battle, Eruption will hit both opponents. In a Triple Battle, Eruption will only hit opposing adjacent Pokémon.
Eruption will also destroy round rocks found in the background of battles.
