Betanotice.gif Gameplay Notice

Gamma Urayne is currently unavailable during regular gameplay, and as such only CURIE can currently use this ability.

In-game description
The Pokémon summons a nuclear fallout when it enters battle.
  • This ability was created for Pokémon Uranium

Chernobyl is an ability introduced in Pokémon Uranium which summons a new weather condition. It is the signature ability of Gamma Urayne.


In battle

Chernobyl creates a Nuclear Fallout for the duration of the Pokémon being in battle, dealing damage every odd-numbered turn to all Pokémon except Nuclear- and Steel-types. This damage is based on each Pokémon's weakness to the Nuclear type, much like the damage taken from Stealth Rock or a Thunderstorm. Additionally, it will reduce the damage Nuclear-type Pokémon take from super effective moves. It can't be removed by switching in a pokemon that would summon another weather condition, like Yatagaryu's ability Stormbringer.

Outside of battle

Chernobyl has no effect outside of battle.
