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, this move's animation display changes.
