After Bide is selected, the user will be unable to select a move or switch out for an idling period of 2 turns. Afterwards, Bide will do damage equal to twice the damage received during the idling period. Although Bide is a Normal-type move, type has no effect on the calculated damage inflicted by this attack; thus, Bide does not receive same-type attack bonus. Bide is unaffected by accuracy and evasion modifiers, and can hit Pokémon during the semi-invulnerable turn of moves such as Dig and Fly. Bide hits Ghost types, although they are immune to Normal-type moves.
The damage received during the period is counted as equal to the last amount of damage done. The last amount of damage done will include crash damage, an opponent's self-inflicted confusion damage, and the full damage absorbed by a substitute. Additionally, if the opponent does not use an attack that misses, the last amount of damage done will not be reset, effectively resulting in damage done during the previous turn also being counted as damage done during that turn.
Sleep, freeze, partial trap duration, and flinching will disrupt the duration of Bide.
