Sabre is the nominal leader of the Brotherhood of Guardians and the son of Athair, the only Guardian to have ever left Brotherhood. This decision of Athair's, coupled with the fact that he effectively abandoned his mother Janelle-Li in Sabre's eyes, led to a rift between the two that has not yet healed. Sabre participated in a number of activities against the Dark Legion in Knuckles' time, before ending up imprisoned in the Twilight Zone by Dr. Finitevus.
Sabre was born to Athair and Crystal-La, his mother was a member of the Lost Tribe of Echidnas. Until he was seven years of age, Sabre lived with the tribe, serving under his father. Eventually, the Ancient Walkers told Athair that his mother was dying, and Sabre encouraged Athair to go to his grandmother. When Athair refused, Sabre left for Angel Island and took on the Guardian role himself, becoming apprenticed to Archimedes, the same Fire Ant who would later train his son Locke and his grandson Knuckles. From this point on, Sabre refused to speak to his father, ashamed that he would not help his grandmother.
The Queen Alicia Incident
During the Great War, Queen Alicia was sent to Angel Island with her infant son Elias by King Max to avoid the risk of her being captured or killed as the Overlanders pushed closer to and closer to Mobotropolis. Shortly before they arrived, a group of Overlander attack ships shot down her vessel. Sabre was put in charge of the mission to inspect the wreckage and search for survivors. The Brotherhood discovered the dying queen and her son still alive, but before they could take them to safety the Overlanders arrived. Sabre managed to deceive the Overlanders into thinking everyone died in the crash. Due to the Echidnas non-involvement in the Great War and overall neutrality, the Overlanders took Sabre for his word and left. After they departed, Sabre end the others took the queen and prince to Haven where the queen was put in cryo-stasis until a cure could be found for her wounds. Elias was raised until he was a teenager before being sent into the care of Colonel Sommersby.
After Echidnaopolis' Return
Sabre and Locke intervened the most in events in Echidnaopolis and on Angel Island in general following the city's return to Mobius. Their most radical action involved using their link with the Chaos Emeralds against Mammoth Mogul during his battle with Super Sonic, Hyper Knuckles, Turbo Tails, and their allies. This resulted in the creation of the Master Emerald.
When Knuckles ended up in Haven, Sabre disagreed with his ancestors Thunderhawk and Sojourner, suggesting they allow Knuckles to come to his senses and explain to him all about Haven. Spectre agreed with Sabre and the group allowed Knuckles to come to and learn the secrets of Haven. While Knuckles was originally furious for being kept in the dark so long, Sabre managed to explain that they were simply trying to protect him.
When the Dark Legion managed to locate Haven due to Moritori Rex providing its location, Sabre was tranquilized along with Sojourner and Thunderhawk by a Dark Legion surprise attack. The three remaining in captivity until they were rescued by Locke and Spectre.
Some time later, Sabre would join the rest of the Brotherhood in fighting the Dark Legion, notably following his ancestor Mathias and the others in attacking the Dark Legion at the Grand Conservatory. Sabre, along with the others, was transported to the Twilight Zone by the Quantum Beam and later returned home by Knuckles to find Haven in ruins.
Last Stance and Captive
Some time during 3237, Sabre and the other members of the Brotherhood defended the Master Emerald from Dr. Eggman's armies. Although they successfully held off the attack, they fell helpless into the clutches of Dr. Finitevus and Dimitri in their weakened state. The mad scientists studied the Brotherhood to learn more about their Chaos abilities before dispatching them all to the Twilight Zone once again.
Unlike Sojourner, Sabre had a more liberal and modern mentality when it came to the Brotherhood's policies. When his grandson Knuckles stumbled upon Haven, Sabre was opposed to Sojourner and Thunderhawk's proposal to send Knuckles back to the Sandopolis Desert before he came to his senses, believing fate had simply taken its course.
Additionally, he felt that the Brotherhood were not hypocrites for using excessive technology despite their society's ban on it. Instead, Sabre saw it as "the means to allow a level playing field" with the Dark Legion, whose technological level was on par with Dr. Ivo Robotnik's.
- Sabre's early appearances in KtE #4 and StH #56 depicted him as a very old man with red fur, but by KtE #16 he appeared much younger and with brown fur.
- Some believe Sabre to have a glass eye. In fact, he is merely wearing a monocle.
