Raptorus

Leader of the Terracons, Raptorus is a wyvern (a creature with features similar to those of dragons, bats and goats among other animals). Around 500 years after the first defeat of Queen Necrafa of the Spectral Hand by the original Mysticon Dragon Mage, Raptorus' kind were mostly enslaved if not tortured and slain by humans and elves to the point of endangerment when he was a mere hatchling. Over the next more 500 years since then, as Raptorus grew to his adult stage, so did his grudge against such creatures.
