- Primitives. Together, strong!
Caesar (formerly Primitive Zero, or the First Primitive) was a chimpanzee who was the first ever primitive to be born into existence. He was created after Dr. Herbert Wyndham tested on him to see what he created after accidently cracking the genetic code and discovering a new "primitive" animal genome. Caesar's legacy would carry within his grandsons, Apelink and Milo.
- He is similar to Cornelius from the original Planet of the Apes films. In the original films, Caesar (born Milo) has a son with his wife Lisa whom they name Cornelius after Caesar's father. Like Cornelius, Caesar never knew his grandchildren.
