In Tales of Xillia
For a while, he tried to get to and use the Lance of Kresnik for his own purposes. However, after a skirmish with Jude, Milla, and the group, everyone found out that Gilland had his hands on it and that it could drain everyone's mana at once. Both their groups decided to work together to infiltrate the E.S.S. Zanethra and defeat Gilland.
Unfortunately, after Gilland's defeat and Milla's "death", Gaius formed an alliance with Muzét and set off to destroy every spyrix in existence (which would cause suffering to Elympois) and to kill Maxwell. They also raided through a research center. Later on, he gave Jude and Milla Muzét's knife that they could use to return to Razie Maxia in return for not interfering with his plans. They did so anyway by pursuing Giaus and Muzét inside the Dimentional Breach.
During the final battle, Jude and Milla began fighting with both Gaius and Muzét at once. Gaius was shown to be at full power and determined to kill them for good. After the rest of the party came in, they each used their Mystic Artes. In the end, after the fight, Gaius was convinced by Jude to abandon his plans. During the ending, he was seen with Rowen briefing with a few soldiers.
