Fusion Bolt inflicts damage. The base power of Fusion Bolt will double if another Pokémon uses Fusion Flare immediately before the Pokémon using Fusion Bolt, but only during that use. Likewise, it will double the power of Fusion Flare if Fusion Bolt is used immediately before the Pokémon using Fusion Flare, during that use. When Fusion Flare is used before this move is used, or a critical hit is made, this move's animation display changes.
Bold indicates a Pokémon gains STAB from this move. Italics indicates a Pokémon whose evolution or alternate form receives STAB from this move.
