Dig.......

Type Ground
Category Physical
PP 10 (max. 16)
Power 80
Accuracy 100%

On the turn that Dig is selected, the user will dig underground, where the only attacks it can't avoid are Bide, Swift, and Transform. On the following turn, Dig will do damage, PP will be deducted from it, and it will count as the last move used. Once Dig is selected, the user won't be able to switch out until it is disrupted or fully executed.
If Dig 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 digs underground, Mirror Move will copy the move that the user executed immediately before using Dig (or fail if it can't).
Confusion and full paralysis will disrupt Dig. Additionally, if the user is fully paralyzed during the mostly-invulnerable turn of Dig, the mostly-invulnerable part will not be reset until the user switches out or fully executes Dig.
In Stadium, Dig will allow the user to avoid damage reversed by Bide. Full paralysis will reset the mostly-invulnerable part of Dig. Mirror Move will copy Dig on either of the turns it takes to execute.
Dig has a power of 100 in Generation I.
