The Devil Stallion is a strange creature that is a mixture of DNA of horses from ancient Rome and Aludran Reptiloids . The Reptiloid DNA gives it the ability to breathe fire, making it quite powerful. In addition, they also gave it a pair of wings in order to fly. To top it off, Mental's researchers gave it an undying loyalty to Mental and cast some black magic on it in order to make it more resistant to enemy attacks. All of these factors make the Devil Stallion a very dangerous foe to fight.
It has two attacks, a fire breath that it will use while flying and while stationary. Most of time it will fly, but occasionally it will get on the ground and walk for a little bit.
