Dragon Energy  

Dragon Energy is a damagedealing Dragontype move. It is the signature move of Regidrago.
Effect
Dragon Energy deals damage. It has 150 base power at maximum HP, but its base power decreases proportionally to the user's remaining HP.
Specifically, its base power is equal to 150 x HPCurrentHPMax. However, if this formula produces a value less than 1, the move's base power becomes 1 instead.
 HPCurrent is the current HP of the Pokémon.
 HPMax is the maximum HP of the Pokémon.
