Caesar is raised by Will Rodman, the scientist in charge of the experiment, and his girlfriend Caroline Aranha after the death of his mother, but is forced to live in captivity at the San Bruno Primate Shelter after attacking a neighbor.

Caesar maintains dominance over his community of intelligent apes while also having to deal with the threat of war against human survivors, who had been pushed to near-extinction due to a pandemic known as the Simian Flu, originating from the ALZ-113 virus.

As Hasslein killed the infant with Zira deposing of the body, Milo was assumed dead and was raised by Armando as a mute acrobat who was renamed "Caesar".

Caesar is taken to a city for the first time and sees groups of apes being dispersed, chimps and orangutans being scolded or punished for honest mistakes or for exhibiting apelike behavior.

[2] Passing his conditioning with flying colors, Caesar is held at an auction and is sold to Governor Breck and supervised by his assistant Mr. MacDonald.

But Caesar is belatedly traced, where he soon gets captured and then gets interrogated and tortured by Breck, who forces him to expose his identity as the offspring of Cornelius and Zira.

The movie is told as a flashback, where the beginning and ending scene takes place 600 years after Caesar's death and it shows the Lawgiver telling a story to a group of both ape and human children.

He tells them the story about how Caesar fought a battle that solidified his position as ape leader and convinced him to give a joint ape-human society a chance, instead of one species dominating the other.

[5] Caesar is the main protagonist of the reboot series, sharing the previous version's compassionate nature while forbidding his followers from killing innocent humans and those who don't seek to harm them.

First appearing in Rise of the Planet of the Apes, Caesar is the son of a female chimpanzee Bright Eyes who was taken from the African wild to the pharmaceutical company Gen-Sys in the San Francisco Bay Area to be subjected to an experimental viral-based cure of Alzheimer's known as ALZ-112.

When born, Caesar ends up orphaned after his mother is killed trying to protect him, an action mistaken by lab security after she runs amok, which labels the experiment a failure.

Following an incident where he attacks their aggressive neighbor who threatens Charles, Caesar is forced to stay at the San Bruno Primate Shelter, an ape sanctuary where he is tormented by one of the caretakers while gradually taking command of the apes, while also developing a close friendship with a Bornean orangutan named Maurice.

Caesar eventually proves smart enough when he breaks free from his cage, steals the ALZ-113, a stronger version of the intelligence-enhancing formula and releases it among the other captive apes.

In Dawn of the Planet of the Apes, set ten years after the ALZ-113 virus decimated most of the human population, Caesar is now middle-aged and mated to Cornelia.

Later, the Colonel launches an assault on the apes' home, where he kills Cornelia and Blue Eyes, leaving only Cornelius alive.

Leaving Cornelius in the care of Blue Eyes' mate Lake, Caesar departs to confront McCullough, accompanied by Maurice, Luca and Rocket, while the other apes head for the desert.

After unintentionally killing the albino western lowland gorilla Winter for betraying the location of the apes to the humans, Caesar fears that his desire for vengeance may cause him to end up like Koba.

[8] The opening scene of Kingdom of the Planet of the Apes reveals that Caesar's body was cremated on a funeral pyre shortly after his death.

Andy Serkis's performance as Caesar in the rebooted Planet of the Apes trilogy garnered massive critical acclaim.
