Dual Chop is an offensive multi-attack Dragon-type move. Each hit has an equal chance to be a critical hit.
Dual Chop will hit again if the first strike breaks a substitute. Bide only acknowledges the second strike of this move. If the target has an ability activated upon contact, the ability has the chance to activate on both strikes. If the first strike activates the target's Focus item or Sturdy, the second one will cause the defending Pokémon to faint. A Focus Band can still activate again to prevent fainting, but this chance is independent of the previous one.
As of 1.0.4, it can be taught by the Physical Move Tutor of Tsukinami Village Hotel for four Red Shards. In 1.0.3, it could be taught by the Ultimate Move Tutor in Tsukinami Village, at a cost of 4 of each type of shard.
