Spikes is a non-damaging Ground-type move.
Spikes sets an entry hazard around the enemy team's field, causing damage for Pokémon who switch in. Spikes can now be set up to three times, each increasing the damage done to the opponent upon switching in. One layer of Spikes will damage the opponent Pokémon by 1/8 (12.5%) of its maximum HP, two layers will deal 1/6 (16.67%), and three layers will deal 1/4 (25%). Any Pokémon with Levitate will also be immune to the damage.
Spikes do not affect Flying-type Pokémon or Pokémon with the ability Levitate or Magic Guard. Flying-type Pokémon and Pokémon with Levitate take damage if they are affected under Gravity, holding an Iron Ball, or if Baton Passed an Ingrain. The moves Rapid Spin and Defog remove the effect of Spikes; Rapid Spin removes Spikes set around the user of Rapid Spin while Defog removes Spikes on both sides.
If a Pokémon is holding an Air Balloon, it will not be affected by Spikes, unless Gravity is in effect. Spikes can also be reflected with Magic Coat or the ability Magic Bounce.
