The Thunder Puppy form is one of the Puppies obtained after meeting the fire Shaman Sana who attempts to merge powers with Ryu. Unlike in Breath of Fire, in Breath of Fire II Puppies act as a spell other than a transformation. Using it will take drain all Ryu's AP and will trigger him to transform into the Puppy, attack, then transform back which will end his turn. The Thunder Puppy's attack does a base damage of 256 electric damage.
