Carnassials is a pony who was born in Carnivora city. His main purpose is to fight, overcome and break down anything which come deep into the city. He has his twin brother but it is in the opposite side of the crystal cave where he lives and protects the city.  
He slices incomers with his shearing ability. He is ridden usually by Masseter and Temporalis mostly.
 
Trivia: Only one of the brothers can fight in one time.
 
He can become an Unicorn and be even more effective during fighting, but only temporarily, when he’s getting sharp enough because of self sharpening hooves action.
