Semper Fidelis

Semper Fidelis is a member of the Fire Ant Council, a group closely aligned with the Brotherhood of Guardians. The son of Deo Volente and the father of Archimedes, Semper mentored a number of Guardians, the last being Athair, who left that organization to lead the Lost Tribe of Echidnas. Since retiring from his teaching role, he has remained an adviser to the Brotherhood, and after their disappearance joined the Angel Island resistance against Dr. Eggman and his Dingo allies.

History
Semper's history is largely unknown, with Athair being the only confirmed Guardian to be trained by him. Following Athair's departure from the role of Guardian, Semper passed on his teaching role to his son Archimedes. Since that time, he has served as one of several Fire Ant advisers to the Brotherhood, notably taking part in a discussion in which the Brotherhood contemplated Mobius' situation in the aftermath of the death of Dr. Robotnik. Semper and his father Deo agreed that the Brotherhood lacked focus in their goals, and Semper reminded the Brotherhood that even though they focused primarily on the interests of the Angel Island Echidnas, the interests of outside powers could affect their people as well. It was then the middle generation Fire Ant who gave the Brotherhood his view of their choices: to stand by and let their people become an insignificant force on Mobius, or to take charge and lead the Echidnas and the rest of Mobius into a new age of prosperity. Sadly, the arrival of Dr. Eggman prevented the implementation of Semper's dream, and when the Brotherhood vanished as they defended the Master Emerald, Semper and his family found themselves among the few Fire Ant Council members to have escaped the Egg Grapes. Allying themselves with General Von Stryker, deposed leader of the Dingoes, the Fire Ants continued to resist Eggman's occupation up until the point when the second Enerjak overthrew the Dingo regime.
