Back Boost (move)

Back Boost is a move released in Pokémon Sun & Moon Vesions.

Its effect is to paralyze the user, but it switches out with another Pokémon from the user's party. The Pokémon sent out would then have its Speed and Attack stats sharply raised and its Special Attack raised 1 stage. However, if used by a Pikachu or Raichu, instead of paralyzing itself, it lowers its HP down to 1, maxes out the Speed and Attack of the sent out Pokémon, and sharply raises the Special Attack of the sent ot Pokémon.

Trivia

 * If used by a Pikachu and Raichu, their HP is only allowed to be healed up to the halfway mark. They also selfdestruct on their second use of this move during the same battle. Their HP can only be fully healed outside of the battle
