Pokémon Gold Version, Silver Version, and Crystal Version - Multi-hit attacks
The multi-hit attacks are labeled "Multi-hit attack" and "Attacks twice in a row" in the attack descriptions, as well as Triple Kick and Beat Up. For all multi-hit attacks, an accuracy check is performed only once, namely, before the attack hits the opposing Pokémon multiple times.
When the opposing Pokémon of a multi-hit attack faints, the attack stops.
Unless noted otherwise, each hit of a multi-hit attack is treated as a separate attack. For instance, the chance of a critical hit is checked separately for each hit.
