Caesar is a tall man in his early twenties. Being half-Mexican and half-Argentinian, Caesar has a darker skin tone, brown eyes and dark hair which seems to be naturally spiky. His facial features are similar to Rex's, only more angular, with the addition of small lines near his eyes. Caesar wears a khaki vest with a green long sleeved shirt underneath and green pants. He also wears heavy, military-like boots.
He made an appearance in the crossover. It was stated that he had created Alpha, but he became too dangerous, causing Caesar to send him to the Null Void.
