Slow Start (Japanese: スロースタート Slow Start) is an Ability introduced in Generation IV. Prior to Generation IX, it was the signature Ability of Regigigas.

In battle

Generations IV to VII

Slow Start causes the Attack and Speed stats to be halved during the first five turns in battle. This counter is reset if the Pokémon is switched out.

If this Ability is replaced due to a move like Skill Swap or Worry Seed or is suppressed, the Pokémon's stats return to normal.

In the Japanese version of Pokémon Diamond and Pearl, removing Slow Start does not undo the Attack and Speed drop; it must still wait five turns. This was changed in localized versions as well as in Pokémon Platinum.

Foul Play uses the target's halved Attack stat to calculate damage.

If the user holds a typed Z-Crystal and uses a Z-Move based on a special move, Slow Start will also reduce the Special Attack stat for the duration of that move only.

Generation VIII

In Pokémon Legends: Arceus, Abilities do not occur in normal gameplay. However, Slow Start has been reworked into a status condition exclusive to Regigigas. Regigigas will gain the Slow Start status condition upon entering battle for its first five turns, halving its Attack and Speed stats. Due to the different way damage is calculated in this game, Slow Start's effect on Attack is much less impactful on damage output than in other games.

Outside of battle

Slow Start has no effect outside of battle.
