Behemoth Bash (Japanese: きょじゅうだん Behemoth Impact) is a damage-dealing Steel-type move introduced in Generation VIII. It is the signature move of Zamazenta.



Behemoth Bash deals damage. If the target is Dynamaxed or Gigantamaxed, its base power is doubled to 200. The bonus does not apply to Eternamax Eternatus, despite its similarities to a Gigantamaxed Pokémon.


Games Description
SwSh The user becomes a gigantic shield and slams into the target. This move deals twice the damage if the target is Dynamaxed.


Special move

If Zamazenta knows Iron Head while entering battle in its Crowned Shield form, Iron Head will become Behemoth Bash for the duration of the battle.
