Firat + Barrisum + Chistroy

Firat: Pre-evolved form (baby)of Yarat. They are highly resistant for their size and tend to launch themselves at enemies.

Barrisum: Evolved form of Roadsum while equipped with Dragon Fang (but he's not a dragon type). It evolved multiple heads on its body that look like vulnerable Roadsums. The attacker is then taken by surprise in a fury of fists. Its body is also covered with scars from the road.

Chistroy: Evolves from Scurro by leveling up in Lt. Surge's training facility. It wields explosives for combat rather than its fire breath which consumes energy. It is based on the historical fact that soldiers attempted to train bats into dropping bombs on enemy troops in WW2.
