Magnet Rise fails if used by a Pokémon under the effect of Smack Down; the move Telekinesis cannot affect a Pokémon under the effect of Smack Down. The Air Balloon does not apply if the Pokémon is under the effect of Smack Down.
Smack Down can hit Pokémon during the semi-invulnerable turns of Fly, Bounce, and Sky Drop. If it hits a Pokémon that is using Fly or Bounce, it will knock it down, cancelling the move; if it hits a Pokémon using or affected by Sky Drop, it will not be knocked down. A Pokémon under the effect of Smack Down can still use these moves on subsequent turns.
Dwebble opens its mouth and a metallic gold orb of energy that is surrounded in orange energy appears in front of it. Dwebble then fires the orb at the opponent. When the orb hits the opponent, it explodes. If the opponent was in the air when the orb of energy explodes, the opponent shoots straight down to the ground.
Regigigas creates several glowing orange energy globs between its hands. Energy globs become brown stones and Regigigas fires orange energy at the opponent with a trail of that stones. The hit is followed by an explosion.
The English name of this move may be an homage to former professional wrestler Dwayne Johnson, who is associated with the coining of the word smackdown, and shares his ring name, The Rock, with the type of the move.
