When performed, Pichu starts charging electricity, creating a small circular area around him that pulls opponents towards it. It then delivers a massive electric attack around itself to continuously attack opponents caught in it, dealing weak electricdamage at first before ending with a powerful flash with strong knockback. The move deals up to 50% damage in total to opponents, but it also deals 15% recoil damage to Pichu over its duration. After the move ends, platforms in the radius of the attack will briefly be covered in electricity, which deals 21% damage and moderate knockback to opponents that make contact with it.
Electric Terrain is a non-damaging Electric-type move introduced in the Generation VI Pokémon games, Pokémon X and Y. Using this move will electrify the battlefield, preventing any Pokémon on the ground from sleeping and boosting the power of their Electric-type moves by 50% for five turns (eight if the user holds a Terrain Extender). Pichu can learn this move in Generation VII through breeding, as well as Generation VIII through TM90.

This is Pichu's only special move that is not affected by Discharge.
One of the poses Pichu makes during the move is the same pose it makes in its in-game sprite in Pokémon Silver.
Early in the move's development, several different functions were considered. For one of these, Pichu would create a large yellow circle of electricity around Pichu, which Pichu would be able to move and attack freely with. It would attack opponents that made contact with the edges of the circle and knock them into it.
