Magus is a major anti-hero in Chrono Trigger.
Janus was the son of Queen Zeal during the Dark Ages. His mother became maddened after discovering the existence of Lavos, an alien parasite that dwelled beneath the planet's surface. Becoming a power-hungry queen, she used the Mammon Machine, a device created by one of the three Time Gurus, to channel Lavos's power, which would allow her to become immortal. She eventually summoned Lavos itself, which prompted the opening of a time gate that sent Janus, along with the three Time Gurus, to different parts of history. Lavos unleashed its power and destroyed the Kingdom of Zeal completely.
Janus ended up in the Middle Ages, where he bumped into Ozzie, who attacked him with his minions. Janus somehow convinced Ozzie that he came to the Middle Ages to lead the Fiends to conquer the world. Janus changed his name to Magus, and as he grew, he became an extremely powerful sorcerer. He essentially had only one goal in mind: to destroy Lavos at all costs. For this purpose, he spent years studying storybooks as well as arcane magic, at the same time during which he led the Fiends in their war against humans. He was helped by his three henchmen: Ozzie himself, Slash and Flea. He was challenged by Cyrus, the legendary hero who wielded the legendary sword known as the Masamune, but Magus easily killed him, also turning his friend Glenn, who watched the entire scene, into an anthropomorphic frog in the process.
When the time came, Magus summoned Lavos and fought him, but he ended up being killed while his castle was completely destroyed. Without their leader, the Fiends lost their war against humans. The remaining Fiends built the Medina Village, where they continued to socially distance themselves from humans. Somehow, the Fiends were thoroughly convinced that Magus created Lavos so that he could use it to destroy the world, so history recorded said assumption as the truth.
After visiting the ruined future, Crono, Marle and Lucca, along with Robo, began looking for clues on how to destroy Lavos and therefore save the future. They visited Medina Village during the present time, where they were told by the monster Heckran that Lavos was created by Magus. They then decided to defeat Magus in the Middle Ages so that Lavos would never be created. They eventually convinced Frog to re-join their group after giving him the restored Masamune, so said group then sets after Magus' Castle. Inside said castle, they fought and defeated Slash and Flea, so Ozzie made a last-ditch effort of his own to stop their progress, only to end up ironically falling into a pit that he himself created. Crono's group then proceeded into the castle shrine, where Magus wass making his ritual to summon Lavos. Stopped by Crono's group, he fought said group. After a fierce battle, Magus ended up being defeated, but said defeat caused his ritual to go awry, creating a massive time gate that sent Magus back to the Dark Ages while Crono's group was sent to the Prehistoric Age.
After being sent back to his native time period, Magus decided to take advantage of his knowledge of past events and disguise himself as a prophet in order to gain the trust of Queen Zeal. When Crono and the others arrived in the Dark Ages and made their way into the Zeal Palace, they were greeted by said queen, who had already been expecting them due to the fact that Magus had already told her that they would arrive and cause disaster. She ordered her lackey, Dalton, to finish them, so he summoned a Golem that easily defeated all of them. Trapped where the Mammon Machine was, they were then rescued by Schala, who is the Queen's daughter and Magus' sister, but Magus interrupted and ordered Schala to send them back to where they came. They went to the time gate from whence they had came and entered it, as Schala sealed it shut. However, Crono's group eventually found the Epoch, which was created by a Time Guru named Belthasar, in the future.
Back in the Dark Ages, Crono's group entered the Ocean Palace to chase after Queen Zeal. In said palace's inner chamber, said queen was forcing Schala to use her magical powers to operate the Mammon Machine at full power, while Magus was watching. When Crono arrived, he used a dagger given to him by a Time Guru named Melchior to stop the machine, but unfortunately, it was already too late. Lavos emerged from its slumber and attacked everyone. Magus finally revealed himself and attacked Lavos with all of his might, but he was unable to even scratch said monster; all the while, Lavos was also draining away his magic powers. Crono then made an incredibly desperate final attempt to stop Lavos, but ended up being thoroughly killed by said monster. History repeated itself, and the Kingdom of Zeal was destroyed. Meanwhile, Schala used her remaining magical power to save Magus and the others.
Later on, Magus was busy depressedly watching over the ruined land of the Dark Ages from a cape, when Frog confronted him. Magus revealed everything about both himself and Lavos, also blaming Crono for being a reckless fool and getting himself killed by Lavos in the process as he does so. Frog gets extremely offended by Magus' words, but Magus is more than eager to take him on. If the player made the correct moral choice in said scenario, however, Frog ultimately gave up on fighting Magus, since killing Magus wasn't going to bring Crono or Cyrus back. As Frog tried to leave the place with his fellow main protagonists of the game, however, Magus called them and offered to join them, since both he and them had essentially the same goal. He helped them resurrect Crono and later defeat Lavos. After Lavos was destroyed, Magus immediately went straight back to the Dark Ages in hopes of finding Schala and re-uniting with her.
Magus is vengeful and a very determined person. He is remarkably cold to those around him, including his comrades. Even as a child, he was cold and distant, especially towards his mother, who he knew was being corrupted by Lavos. He rarely speaks with others, and when he does, his purpose for doing so is often to threaten them. Magus even has a rather dark sense of humor, making fun of Frog's predicament after transforming Glenn into said frog. He does, however, possess some good qualities and also genuinely care about Schala, who seems to be the only other member of his family that he actually cares about. To Magus, the ends justify the means, and therefore, he is willing to go to great lengths just to have revenge against Lavos. After Lavos is defeated, Magus remains a loner and leaves shortly to find his sister Schala. Despite this, however, Magus stays very loyal to his allies and has helped his friends defeat some very powerful foes.
