The user becomes uncontrollable and attacks for 2-5 consecutive turns; the target cannot make attacks of its own during this time, but it may switch out, use items or run away.
Attacks 2-5 times in one turn; if one of these attacks breaks a target's Substitute, the target will take damage for the rest of the hits. This move has a 3/8 chance to hit twice, a 3/8 chance to hit three times, a 1/8 chance to hit four times and a 1/8 chance to hit five times.
Attacks 2-5 times in one turn; if one of these attacks breaks a target's Substitute, the target will take damage for the rest of the hits. This move has a 3/8 chance to hit twice, a 3/8 chance to hit three times, a 1/8 chance to hit four times and a 1/8 chance to hit five times.
Damages opponents, unless they are Flying-type or have Levitate, every time they are switched in; hits through Wonder Guard. Can be used up to three times: saps 1/8 of max HP with one layer, 3/16 of max HP with two layers and 1/4 of max HP for three layers.

Almost always goes first. The user is protected from all attacks for one turn, but the move's success rate halves with each consecutive use of Protect, Detect or Endure. If a Pokemon has No Guard, or used Lock-On or Mind Reader against the user during the previous turn, its attack has a [100 - move's normal accuracy]% chance to hit through Protect; OHKO moves do not benefit from this effect. Blizzard has a 30% to hit through this move during Hail, as does Thunder during Rain Dance.
Opponents will be poisoned as they enter the field until they use Rapid Spin. One layer inflicts regular poison while two layers inflict Toxic; switching in a non-Flying-type Poison Pokemon without Levitate will remove any layers. Flying-type and Levitate Pokemon are only affected if they switch in while Gravity is in effect, Iron Ball is their held item or they are receiving a Baton PassedIngrain; Steel-type Pokemon and Pokemon who enter with Baton PassedSubstitutes are not affected.
