Percy Jackson and the Olympians: Legends

Caligula was young, slender and lithe. He was handsome in a thin angular way, though his ears stuck out a bit too much and were too prominent. His smile was twisted and too thin, and his placid brown eyes that were too far apart had "all the warmth of a barracuda's". Caligula was dressed in white slacks, white boat shoes, a striped blue-and-white shirt, a blue blazer, and a captain's hat.

Caligula is considered one of the most (if not the most) malevolent Roman emperors in history. Indeed, he is so cruel and ruthless, that even his nephew Nero is said to fear him. Caligula shows little to no concern at all to his subordinates, regularly ordering the execution of anyone who displeases or fails him, Incitatus being the only exception, as he is the only follower whom the god-emperor views as an equal. He also kills any subordinates whom angers him whether it is be with bad news or other things. Caligula is also extremely power-hungry, always seeking to achieve more power. Back to his reign as emperor, he would disguise himself as several major Olympian gods, such as Mars, Jupiter, or Apollo, and he even gave himself the alias "Neo Helios", which meant "New Sun".

Gaius Julius Caesar Augustus Germanicus, better known as Caligula, was a Roman Emperor who was made a god-emperor by his followers. He was a Triumvirate Holdings leader alongside Nero and Commodus. He was killed in an explosion caused by Frank Zhang during the Battle of San Francisco Bay.
