Leonidas (レオニダス), also known as the Behemoth (
Leonidas was born in a family of warriors and raised in east-central Zemuria. His remote hometown was rich with septium, making it a target for bandits and armed merchants. Eventually, the merchants invaded with a military airship. Leonidas managed to repel their invasion thanks to Zephyr commanding officer Garcia Rossi, who happened to be in the vicinity at the time. Ever since Leonidas swore his lifelong loyalty to Zephyr's commander, Rutger Claussell, to return the favour of having his family saved from that fateful incident.
Although first shown in Trails of Cold Steel, Leonidas is formally introduced alongside his companion Xeno in Trails of Cold Steel, Chapter 1: "Unconventional Studies". Serving the Noble Alliance during the Erebonian Civil War, they fight with Class VII at the ruins of Garrelia Fortress and soon thereafter in Ymir. After the Intermission: "Aboard the Pantagruel", Leonidas and Xeno continue their work in western Erebonia until they're called back by Cayenne on December 30 to defend the second stratum of the Infernal Castle, where they faced off against Fie Claussell and the rest of Class VII once more. They revealed to Fie that other Zephyr members had split up on Rutger's orders and that they were working on bringing him back from the grave.
Following Rutger's revival, their work throughout Erebonia leads them to several counters with Class VII, revealing that they only cooperated with the Noble Alliance at the request of their "true employer", the Gnomes, in order to gather intelligence. He continues to work with Xeno, this time as members of Zephyr, to help Alberich and Giliath Osborne spur on the Great Twilight. After preparing the stage for the Rivalry between Rutger and Rean Schwarzer by fighting Class VII, he and Xeno side with them for the infiltration of the Salt Pales.
