Athair

Athair is the son of Janelle-Li, the only female Guardian in the history of the Brotherhood of Guardians. Athair followed the usual Guardian tradition of assuming the position around 8 or 9 years of age, but then was taken by the Ancient Walkers to Haven, where his mother surmised that he had a different destiny. Athair resigned his position, and began learning from the Ancient Walkers. In addition, he became Mitre of the Lost Tribe as they sought their homeland of Albion. When his mother died, he was expected to reclaim the position of Guardian, but he refused. His son Sabre, furious at him, took up the position at age 7. Worse for Athair, his wife Crystal-La was later captured by the forces of Dr. Ivo Robotnik and Roboticized, along with many other members of the Lost Tribe.

His first encounter with the Knothole Freedom Fighters was during time he spent in Downunda. While living in this desert, he took up residence in the Great Crater, once resting place of Angel Island, and became known among denizens of the continent as "Ol' Weirdo" due to his reclusive nature. During his stay, the Downunda Freedom Fighters brought him a guest - the then unconscious Miles "Tails" Prower. Nursing the fox back to health, Athair told Tails stories of Mobius' past and revealed the young Freedom Fighter's destiny as the Chosen One. Shortly afterwards Athair was presumed to have died when Crocbot's escape vehicle crashed into the crater and caused a massive explosion. Instead, Athair merely shed his corporeal form.

Following Mammoth Mogul's success in draining the powers of Enerjak, Athair reappeared to aid the beleaguered opposition, which consisted of Tails, Sonic the Hedgehog, and Knuckles the Echidna. Athair allowed the trio to assume their super forms of Super Sonic, Hyper Knuckles and Turbo Tails and distracted the powerful tyrant. Delivering the Chaos Syphon to his beleaguered allies, he watched as they overcame Master Mogul. This enabled the three heroes to defeat Mammoth Mogul, who was then trapped inside the recently formed Master Emerald.

Shortly afterward, Athair returned to recruit Knuckles, bestowing upon him duties as Mitre of the Lost Tribe. He disappeared again, leaving the tribe in the capable hands of Knuckles. With the assistance of Rob O' the Hedge, Knuckles successfully led the Lost Tribe to Albion. As he left, the faces of Athair and the Ancient Walkers appeared in the clouds above him, smiling down in approval.

Following the Dark Legion's attack on Angel Island with the Quantum Beam, Athair appeared before Knuckles, who managed to jump off the island before being sent to an alternate zone. Athair explained that the answers Knuckles sought could be found in Albion, and that he would need a guide in the form of Rob O' the Hedge. Before vanishing, Athair reminded Knuckles he already had the means to get to Albion.

The next time he showed up, Athair appeared in Knothole High School before Tails, telling him he was needed. After he transported Tails to where Chaos Knuckles was located, he explained that Knuckles was evolving. Shielding Tails from one of Chaos Knuckles' blasts as the echidna teleported away, Athair then transported Tails to the Floating Island where Chaos Knuckles teleported himself to. After Tails was injured in an attack, Athair teleported him to Merlin Prower. Athair informed Merlin that the Ancient Walkers were dying, and that Turbo Tails needed to be summoned to combat Chaos Knuckles, otherwise entire worlds would be destroyed. Explaining the agony his great-grandson was suffering through, Athair convinced Merlin to summon Turbo Tails. After Chaos Knuckles quickly defeated Turbo Tails, Athair probed Tails' mind and discovered that this was a duplicate, the location of the real Tails unknown. Athair explained they should not inform the false Tails of this without knowing how the switch occurred or who was responsible, transporting the duplicate Tails to Knothole.

Athair later returned, apparently having taken up residence in the same dimension as Aurora. Following Knuckles' death and his brief merging with the Chaos Force, Athair asked Aurora why she didn't inform Knuckles he was worth of a second chance at life. Later when Knuckles returned, having rejected being merged with the Chaos Force upon sensing the Xorda threat to Mobius, Athair confirmed to Knuckles he could have a second chance, but warned him the result of returning would have unknown consequences. After Knuckles returned back to life, Athair explained to Aurora Knuckles' young age played a key part in his reasons for rejecting being one with the Chaos Force.

Some time later, Athair appeared to Tails again, appearing only as his disembodied head, explaining how Mogul had replaced Tails with a doppelganger and usurped power from the real Tails. Tails pressed Athair to tell him the full truth about the "Chosen One", but Athair simply vanished. After disappearing, Athair's voice told Tails to be patient, stating that the hour of the Chosen One would soon be at hand. Not long afterwards, Athair help gave Tails the knowledge necessary to combine with his numerous alternate selves to form Titan Tails in order to combat Master Mogul, who had been reshaping the multiverse. After Mogul was defeated and Tails used all his power to undo everything Mogul had done, Athair and Merlin conversed about Tails' decision to return things to normal, and that the only evidence of the battle was Mogul, imprisoned in a Chaos Emerald.
