Bonemerang

Hits twice per use.

Bonemerang deals damage and hits 2 times for 50 power each.
Each strike of Bonemerang is treated like a separate attack:

• Each strike can get a critical hit independently.
• Abilities that activate on contact (Static, Weak Armor, Iron Barbs etc.) activate for each strike.
• If the Sturdy ability, Focus Sash , or Focus Band activates before the final hit, the subsequent hit will still deal damage and therefore cause the target to faint.
• If the first hit breaks a Substitute, the second hit will deal damage to the target Pokémon.
• The move Counter only counters the final hit, but Bide counters the complete damage.
• If the target is wearing a Rocky Helmet each strike will hurt the user.

If the user is holding a King's Rock or a Razor Fang the each strike has a chance to cause the target to flinch

• In Gen 1, each hit will always deal the same damage - if the first is a critical hit, so will the rest.
• In Gen 1-3, Bonemerang ends immediately if any hit breaks a Substitute.
• In Gen 2-4, if a Focus Sash or Focus Band activates before the final hit, subsequent hits do not cause the holder to faint.
• From Gen 9 onwards this move can not be selected in battle.
