Raises the user’s Attack by two stages.
User charges for one turn before attacking. During sunny day, the charge turn is skipped. During hail, rain dance, or sandstorm, power is halved. This move cannot be selected by sleep talk.
Lowers the target’s Speed by two stages.
Badly poisons the target. Never misses when used by a poison-type Pokémon.
User falls to sleep and immediately regains all its HP. If the user has another major status effect, sleep will replace it. The user will always wake up after two turns, or one turn with early bird. This move fails if the Pokémon cannot fall asleep due to uproar, insomnia, or vital spirit. It also fails if the Pokémon is at full health or is already asleep.
Transfers 1/4 the user’s max HP into a doll that absorbs damage and causes most negative move effects to fail. If the user leaves the field, the doll will vanish. If the user cannot pay the HP cost, this move will fail. The doll takes damage as normal, using the user’s stats and types, and will break when its HP reaches zero. Self-inflicted damage from confusion or recoil is not absorbed. Healing effects from opponents ignore the doll and heal the user as normal. Moves that work based on the user’s HP still do so; the doll’s HP does not influence any move. The doll will block major status effects, confusion, and flinching. The effects of smelling salts and wake up slap do not trigger against a doll, even if the Pokémon behind the doll has the appropriate major status effect. Multi-turn trapping moves like wrap will hit the doll for their regular damage, but the multi-turn trapping and damage effects will not activate. Moves blocked or damage absorbed by the doll do not count as hitting the user or inflicting damage for any effects that respond to such, e.g., avalanche, counter, or a rowap berry. magic coat still works as normal, even against moves the doll would block. Opposing Pokémon that damage the doll with a leech move like absorb are healed as normal. It will also block acupressure, block, the curse effect of curse, dream eater, embargo, flatter, gastro acid, grudge, heal block, leech seed, lock on, mean look, mimic, mind reader, nightmare, pain split, psycho shift, spider web, sketch, swagger, switcheroo, trick, worry seed, and yawn. A Pokémon affected by yawn before summoning the doll will still fall to sleep. The doll blocks intimidate, but all other abilities act as though the doll did not exist. If the user has an ability that absorbs moves of a certain type for HP (such as volt absorb absorbing thunder wave), such moves will not be blocked. life orb and berries that cause confusion still work as normal, but their respective HP loss and confusion are absorbed/blocked by the doll. The user is still vulnerable to damage inflicted when entering or leaving the field, such as by pursuit or spikes; however, the doll will block the poison effect of toxic spikes. The doll is passed on by baton pass. It keeps its existing HP, but uses the replacement Pokémon’s stats and types for damage calculation. All other effects work as normal.
No moves will hit the user for the remainder of this turn. If the user is last to act this turn, this move will fail. If the user successfully used detect, endure, protect, quick guard, or wide guard on the last turn, this move has a 50% chance to fail. lock on, mind reader, and no guard provide a (100 – accuracy)% chance for moves to break through this move. This does not apply to one-hit KO moves (fissure, guillotine, horn drill, and sheer cold); those are always blocked by this move. thunder during rain dance and blizzard during hail have a 30% chance to break through this move. The following effects are not prevented by this move: * acupressure from an ally * curse’s curse effect * Delayed damage from doom desire and future sight; however, these moves will be prevented if they are used this turn * feint, which will also end this move’s protection after it hits * imprison * perish song * shadow force * Moves that merely copy the user, such as transform or psych up This move cannot be selected by assist or metronome.
Drains half the damage inflicted to heal the user.
The user’s HP cannot be lowered below 1 by any means for the remainder of this turn. If the user successfully used detect, endure, protect, quick guard, or wide guard on the last turn, this move has a 50% chance to fail. This move cannot be selected by assist or metronome.
Has a 30% chance to poison the target.
Only usable if the user is sleeping. Randomly selects and uses one of the user’s other three moves. Use of the selected move requires and costs 0 PP. This move will not select assist, bide, bounce, chatter, copycat, dig, dive, fly, focus punch, me first, metronome, mirror move, shadow force, skull bash, sky attack, sky drop, sleep talk, solar beam, razor wind, or uproar. If the selected move requires a recharge turn—i.e., one of blast burn, frenzy plant, giga impact, hydro cannon, hyper beam, roar of time, or rock wrecker—and the user is still sleeping next turn, then it’s forced to use this move again and pay another PP for the recharge turn. This move cannot be copied by mirror move, nor selected by assist, metronome, or sleep talk.
Changes the weather to sunshine for five turns, during which fire moves inflict 50% extra damage, and water moves inflict half damage. If the user is holding heat rock, this effect lasts for eight turns. Pokémon cannot become frozen. thunder has 50% accuracy. solar beam skips its charge turn. moonlight, morning sun, and synthesis heal 2/3 of the user’s max HP. Pokémon with chlorophyll have doubled original Speed. Pokémon with forecast become fire. Pokémon with leaf guard are not affected by major status effects. Pokémon with flower gift change form; every Pokémon on their side of the field have their original Attack and Special Attack increased by 50%. Pokémon with dry skin lose 1/8 max HP at the end of each turn. Pokémon with solar power have their original Special Attack raised by 50% but lose 1/8 their max HP at the end of each turn.
If the user is burned, paralyzed, or poisoned, this move has double power.

During the immune turn, earthquake, fissure, and magnitude still hit the user normally, and their power is doubled if appropriate. The user may be hit during its immune turn if under the effect of lock on, mind reader, or no guard. This move cannot be selected by sleep talk.
Hits 2–5 times in one turn. Has a 3/8 chance each to hit 2 or 3 times, and a 1/8 chance each to hit 4 or 5 times. Averages to 3 hits per use.
If the target is holding a berry, this move has double power, and the user takes the berry and uses it immediately. If the target is holding a jaboca berry or rowap berry, the berry is still removed, but has no effect. If this move is super effective and the target is holding a berry that can reduce this move’s damage, it will do so, and will not be stolen.
Lowers the target’s Speed by one stage.
If the target is holding an item and the user is not, the user will permanently take the item. Damage is still inflicted if an item cannot be taken. Pokémon with sticky hold or multitype are immune to the item theft effect. The target cannot recover its item with recycle. This move cannot be selected by assist or metronome.

Until the end of this turn, any moves that opposing Pokémon target solely at the user’s ally will instead target the user. If both Pokémon on the same side of the field use this move on the same turn, the Pokémon that uses it last will become the target. This effect takes priority over lightning rod and storm drain. If the user’s ally switches out, opposing Pokémon may still hit it with pursuit. This move cannot be selected by assist or metronome.
For the next 2–5 turns, the target cannot leave the field and is damaged for 1/16 its max HP at the end of each turn. The user continues to use other moves during this time. If the user leaves the field, this effect ends. Has a 3/8 chance each to hit 2 or 3 times, and a 1/8 chance each to hit 4 or 5 times. Averages to 3 hits per use. rapid spin cancels this effect.

Scatters poisoned spikes around the opposing field, which poison opposing Pokémon that enter the field. A second layer of these spikes may be laid down, in which case Pokémon will be badly poisoned instead. Pokémon immune to either ground moves or being poisoned are immune to this effect. Pokémon otherwise immune to ground moves are affected during gravity. If a poison Pokémon not immune to ground moves enters a field covered with poisoned spikes, the spikes are removed. rapid spin will remove this effect from its user’s side of the field. defog will remove this effect from its target’s side of the field. This move does not trigger synchronize, unless the Pokémon with synchronize was forced to enter the field by another effect such as roar.
