Sylva is an intelligent gorilla. He has dark eyes and black fur. He can speak fluently like all other apes from the ALZ-113, a man-made Alzheimer's cure, which killed 99% of humans 300 years ago. He is the Chief Enforcer of Proximus Caesar, a hunter of the Coastal Ape Colony's hunting party, of which the Coastal Ape Colony is lead by Proximus, and the devoted captain of Proximus' guard. Sylva is ruthless, intimidating and extremely brutal, and shows no remorse from any pain he inflicts.
