Octavius is a clever, brave, and experienced general of a Roman legion. Though he seems to lead with grace and wisdom, he can be stubborn and hostile towards people he thinks of as barbarians, such as Jedediah, the cowboy whose glass case sits next to his own. At first, the two do not get along and are unwilling to cooperate due to their apparent differences, and even end up fighting. But seeing as they have no choice they do end up working together and find they have a lot of common ground; they're both great leaders who just want what's best for their people. They become fast friends and are not often seen apart after this. The two, who come to care very much for one another, make a great team and risk their lives more than once for the good of the museum.
Night at the Museum
He is a Roman General in The Hall of Miniatures. He commands his legion to attack Larry using catapults and fireballs after Jedediah's attempts to take him down fails. In the beginning of the film, he is constantly arguing with Jedediah.
The next morning, Dr. McPhee asks Larry why Octavius' mini-figure is in the stockades in the Old West Diorama. Larry just comments that the mini-figures there were not happy that Octavius trespassed and locked him up.
During Larry's second night working as a security guard, after Octavius tries to break through the diorama box wall, Larry grabs Jedediah and Octavius in order to keep their dioramas from feuding. Larry tells them that they better behave or else they will end up like their "friends" from the Mayan Diorama (which Larry previously locked up). This doesn't work when Dexter steals Larry's keys again and runs past them resulting in both dioramas ending up in a feud again while the Mayans still remain locked up.
Near the end of the film, it is thought that he and Jed are dead when they crash the toy car they're driving with Rexy in pursuit into a snow bank with an explosion resulting in the end. However, they turn up later when Larry, Ahkmenrah and Teddy are making sure all exhibits return inside the museum. Octavius reformed after the explosion. They are last seen driving in a new toy car hooked to one of Rexy's bones to make him chase them as Nicky rides on him.
Night at the Museum: Battle of the Smithsonian
Octavius is one of the exhibits that is send to the Federal Archives in the Smithsonian.
Octavius goes on a rescue mission to free Jedediah, who has been placed inside an hourglass by Kahmunrah. After acquiring the help of the Abraham Lincoln statue, he rides on a squirrel that he had earlier fought with to go and get the other exhibits, who have formed an Army. They share a friendly moment during Jedediah's time in the hourglass, before Octavius breaks it to free him. They then fight together against Kahmunrah, Al Capone, Ivan the Terrible, and Napoleon Bonaparte's men.
When they hear that they won the battle, they embrace each other in a hug.
Night at the Museum: Secret of the Tomb
Octavius and Jedediah become lost in the British Museum, and have to find a way to get back to Larry and the rest of the exhibits that accompanied him. When about to die in the musuem vents Octavius asks Jedediah to hold his hand. Larry saves them by turning off the vents, and then the two miniatures venture through the vents until they jump down into a Pompeii display, which the miniatures do not realize is Pompeii until the volcano begins to erupt. They are saved by Dexter, who Larry sent to find the miniatures.
When first meeting the exhibit Lancelot, Octavius comments about his "hypnotic blue eyes".
Near the end of the film, when the tablet is corroding and all of the exhibits are beginning to freeze, Jedediah asks for Octavius' hand.
Secret of the Lost Tablet
At the climax, Jedediah and Octavius sneak into the Washington Museum. Octavius steps out in pirate disguise, with a bandana, an earring, an eye patch, and a stripped shirt that is much too short for him. He keeps trying to tuck it into his pants, with no luck.
