Bloom Doom (Physical) is a Grass-type Z-Move that is only accessible when a Pokémon holding a Grassium Z uses a compatible physical Grass-type move. The power of Bloom Doom varies depending on the base move's strength, but it generally provides a substantial boost, turning the used move into a devastating attack. Unlike regular moves, it does not have an inherent accuracy or secondary effects, as its execution is guaranteed once the Z-Move is activated. Bloom Doom is one of the Z-Moves introduced in the seventh generation of Pokémon games and is often utilized for its ability to break through opponents' defenses, providing a strategic edge in battles.
