Hiro's Fire drake Edit
Hiro's Fire drake is a drake puppy. He originally obtained it when he crashed into the dragon collection world. He later used it in battle, with enough guts, Hiro is able to make it transform into a fully grown fire drake. After the fight with meatmania, Hiro decided to name his drake puppy Papi, and Papi is able to switch between being an entity and being a usable card
~ Hiro most likely named his drake puppy "Papi" because that is the noise the drake puppy makes
