Okay so I had the idea that maybe Ash and Spyro had to fuse in order to be strong enough the beat an opponent. I'll have to say my favorite part is the tail. And yes, they have paws for hands XD
When Ash and Spyro fuse, they get the best of each other, Spyro's strength and Ash's speed. In this form, they have a Z-Crystal to harness their shared Z-Move: Bonded Fire Storm
