Almost always goes first. The user is left with at least 1 HP following any attacks for one turn, but the move's success rate halves with each consecutive use of Protect, Detect or Endure.
Does nothing if the user is awake. If the user asleep, it randomly performs one of its attacks. Rest will fail if it is selected. Sleep Talk's generated attacks do not cost PP, but it cannot generate moves with 0 PP, itself, Assist, Bide, Disabled attacks, Focus Punch, Metronome, Mirror Move, Uproar, or attacks with a charge-up turn like Fly or Skull Bash. (Moves with a recharge turn like Hyper Beam can be generated.)
This move is temporarily replaced by the target's last move; the replacement move will have 5 PP and become part of the user's moveset until the user switches out or the battle ends. Mimic copies attacks even if they miss or the user has immunity toward their type; it cannot copy itself, Struggle, Transform, Sketch, Metronome or moves that the user already knows, and it will fail if the target has yet to use a move.
The user takes one-fourth of its maximum HP to create a substitute; this move fails if the user does not have enough HP for this. Until the substitute is broken, it receives damage from all attacks made by other Pokemon and shields the user from status effects and stat modifiers caused by other Pokemon. The user is still affected by Tickle, Hail, Sandstorm and Attract from behind its Substitute. If a Substitute breaks from a hit during a multistrike move such as Fury Attack, the user takes damage from the remaining strikes.
On the first turn, the user dives underwater, becoming uncontrollable, and evades all attacks except for Surf and Whirlpool, which have doubled power; the user may also be hit underwater if it was previously targeted by Lock-On or Mind Reader or if it is attacked by a Pokemon with No Guard. On the second turn, the user attacks.
Speed is doubled for every Pokemon on the user's team for three turns; the turn used to perform Tailwind is included in this total, as are any turns used to switch around Pokemon.
