Pokemon Fusion is a new feature in Pokemon Inferno and Frost. Every pokemon can fuse with the help of the Fusegg Device. Here is how it works.
Obtaining the Fusegg Device Edit
To obtain this rare and valuable device, you must have at least five gym badges and you must have caught at least 40 pokemon. Once these requirements are done, fly or walk to Skidwald Heights and walk north onto Route 15.
