Skull Bash (Japanese: ロケットずつき Rocket Headbutt) is a damage-dealing Normal-type move introduced in Generation I. It was the signature move of the Squirtle evolutionary line in Generation II. It was TM40 in Generation I.
Skull Bash does nothing on the turn it is selected, other than say that the user lowered its head. On the following turn, Skull Bash will do damage, PP will be deducted from it, and it will count as the last move used. Once Skull Bash is selected, the user won't be able to switch out until it is disrupted or fully executed.
If Skull Bash is not fully executed, PP will not be deducted from it, and it will not count as the last move used. If the opponent uses Mirror Move during the turn that the user lowers its head, Mirror Move will copy the move that the user executed immediately before using Skull Bash (or fail if it can't).
Sleep, freeze, partial trapping, and flinching will pause but not disrupt the duration of Skull Bash.
In Stadium, Mirror Move will copy Skull Bash on either of the turns it takes to execute.
On the turn it is selected, Skull Bash will raise the user's Defense by one level.
If a Power Herb is held by the user, Skull Bash can be executed in one turn.
Skull Bash's power changed from 100 to 130 and its PP changed from 15 to 10.
