Static is an ability introduced in Generation III. So far, 5 Pokémon have this ability.
Moves that make contact with the Pokémon have a 30% chance to paralyze the attacker.
If a Pokémon with this Ability is hit by a multi-strike move that makes contact such as Fury Swipes, each hit has an independent chance to activate this Ability.
Static's ability outside of battle has not been implemented in Pokemon Uranium yet. But will be added in a future update.
Outside of battle
If a Pokémon with Static is leading the party (even if fainted), then there is a 50% chance the game will force an encounter with an Electric-type Pokémon, if one is possible.
