151 (Gijinka AU)

Most likely these characters will be in a story of mine called 151, where wild Pokémon have gone savage, so trainers no longer exist. Humans now merge their DNA with that of the creatures, which allows them to gain some of the features and abilities. 

The legendary Pokemon disappeared, but left relics that had a special trait that pertained to them, allowing a different, yet still deadly sort of fusion. You're either deemed worthy...

Or die.
