Double Slap hits 2-5 times per turn used. The probability of each interval is shown to the right, with the total power after each hit.

Each strike of Double Slap is treated like a separate attack:

The move Counter only counters the final hit, but Bide counters the complete damage.

The Skill Link ability will cause Double Slap to always hit the maximum number of times.

In Generations 2-4, if a Focus Sash or Focus Band activates before the final hit, subsequent hits do not cause the holder to faint.

In Generations 1-3, Double Slap ends immediately if any hit breaks a Substitute.

In Generation 1, each hit will always deal the same damage - if the first critical hits, so will the rest.

When a Pokémon is holding Normalium Z and uses its Z-Power, Double Slap turns into Breakneck Blitz and has base power 100.
