Behemoth Blade (Japanese: きょじゅうざん Behemoth Slash) is a damage-dealing Steel-type move introduced in Generation VIII. It is the signature move of Zacian.

Effect

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

Generation VIII

Pokémon Brilliant Diamond and Shining Pearl

Behemoth Blade cannot be selected in a battle.

Generation IX

As there is no Dynamax mechanic in Generation IX, Behemoth Blade now deals damage with no secondary effect.

Description

In other games

In Pokémon GO, Behemoth Blade is a Charged Attack that debuted on May 29, 2025. It replaces Iron Head when Zacian transforms from its Hero of Many Battles form into its Crowned Sword form. Behemoth Blade can also be used in Max Battles as a Max Move, and can be leveled up as one. Behemoth Blade can't be replaced with another move using Charged TMs. Its Adventure Effect outside of battle, which became available on June 24, 2025, will increase the power of the attacks used by the player's Pokémon by 10% during Raids and by 5% during Max Battles. It costs 5,000 Stardust and 5 Zacian Candy, and lasts 6 minutes.

Trivia

This role is incomplete.
Please feel free to edit this role to add missing information and complete it.
Reason: Behemoth Blade's animation when used through Mimic

If used by a transformed Pokémon, Behemoth Blade will display a shorter animation with the transformed Pokémon stuck in a default pose.
Behemoth Blade and Behemoth Bash were formerly not present in the mobile version of Pokémon HOME's move Pokédex, as they are the signature moves of Crowned Sword Zacian and Crowned Shield Zamazenta (which are forms that appear only in battles and, therefore, cannot be deposited into HOME) and cannot be learned by a Smeargle via Sketch, as it is not present in Pokémon Sword and Shield. With the addition of Smeargle to Pokémon Scarlet and Violet, the former four moves were finally added to Pokémon HOME.
- This distinction is shared with Glacial Lance and Astral Barrage for the same reasoning, as well as Struggle and Light of Ruin, both of which cannot be legitimately learned by any Pokémon.
