Rob O' The Hedge

Following Dr. Ivo Robotnik's successful military takeover of the Kingdom of Acorn, he soon turned his eyes on the distant Kingdom of Mercia. Rob realized that the situation continued to grow worse after his uncle and aunt (Amy's parents) were captured and roboticized. Hoping to prevent his cousin from being roboticized as well, he sent her into the sanctuary of Knothole Village where many had fled from Mobotropolis during Robotnik's coup.

Shortly after Amy was sent away, Mercia fell to Robotnik's forces, and the sub-boss known as the High Sheriff was placed there to quell any future rebellions. Rob assembled a team of Mobians who had managed to escape capture and roboticization, forming the Crazy Kritter Freedom Fighter, while also acting as king of Deerwood Forest. However, the entire group except for Rob was captured and roboticized by the High Sheriff. Rob remained in Deerwood Forest, vowing to fight until he freed the Crazy Kritters and put an end to the High Sheriff's rule.

During Knuckles' tenure as Mitre of the Lost Tribe, he came across Rob O' the Hedge while leading the tribe through Deerwood Forest. When the Lost Tribe was rounded up by the High Sheriff and his Robian minions, Rob' helped to liberate them along with Sonic the Hedgehog and Tails. When the Lost Tribe made it out of the High Sheriff's castle, Rob set it aflame and acted as a diversion so that the Robians did not give chase to the escaping Echidnas. After Sonic and Tail's departure, Rob' lead the Lost Tribe to the edge of a cliff, stating that the "siren call" beckoned him. From there, Knuckles and the Lost Tribe walked over the sea to the city of Albion, finally reuniting them with their homeland. Knuckles however returned to Angel Island.

After the Dark Legion used the Quantum Beam on Angel Island and Knuckles found himself floating alone in the sea, the Guardian used the Guiding Star Gem to take him to Deerwood forest after the spirit of his ancestor Athair told him to seek out Rob O' the Hedge's help. Rob O' the Hedge was soon met by Antoine D'Coolette, Bunnie Rabbot and his cousin Amy. At first, Rob assumed Antoine was the High Sheriff due to the similarities in appearance. He also was unable to identify Amy, as she had aged herself with the Ring of Acorns. Knuckles soon arrived on the scene and explained everything to Rob, as was unable to believe the strangers before him. Shortly afterwards, the group embarked on their journey to Albion to discover what had become of Antoine's father and the citizens of Angel Island, as Knuckles was unaware the Dark Legion was responsible for his people's disappearance.

Unfortunately, the High Sheriff, who was being held in Albion and was to be dismantled, managed to break free of his confines while being inspected by Knuckles and Yanar. In the ensuing battle, Knuckles was transformed into Chaos Knuckles. Rob had the idea of sneaking into the fray by disguising himself, Amy, Bunnie, and Antione as firemen. Unfortunately, the Echidnas of Albion refused to deal with them and Knuckles was forced to warp Antione and Bunnie back to their ship with the High Sheriff in tow, while Rob and Amy wound up back in Deerwood Forest.

Rob and Amy in Knothole.Some time later, Rob escorted Amy back to Knothole, just in time for them to help deal with the Arachne for control of the Sword of Acorns. Shortly thereafter, he was shocked to see the High Sheriff living amongst the rest of the Mobians. Amy informed Rob that the High Sheriff had his free will restored by the Sword of Acorns and was no longer a threat. Rob, ever suspicious of the Sheriff, remained in Knothole for two days to ensure that it was not simply a ploy by his former nemesis. After spending some time with the former High Sheriff, Rob realized he was not the same villain he used to be, having had his free will restored. Now comfortable in the fact his cousin was safe, Rob returned to his home overseas.

During the Xorda's attack on Mobius, Rob participated in the global alliance to combat the Quantum Dial from destroying their world.

During the year of Sonic's absence, Rob O' the Hedge's role as sentry to Albion ended after Dr. Finitevus betrayed his people and allowed the Eggman Empire to destroy the city by providing its location and sabotaging its defenses.

Following Sonic's return to Mobius, Rob attended the ceremony which had Amy Rose officially named a freedom fighter.

Some time later, Rob was standing at Never Lake when his wife Mari-An approached him, having just put their son Jon to bed. The two stood at the lake together when, to their surprise, Silver the Hedgehog appeared and asked Rob if he was Sonic. Rob replied he was not but he knew him, to which Silver responded he needed to find Sonic as his future depended on it.

Rob explained to Silver they could find Sonic at Freedom HQ. Using Silver's super Warp Ring, the two travelled there together. Silver and Rob arrived together to find Sally and Alicia arguing about stranding Sonic and Amy Rose in Moebius. Sally explained to them what had happened, and thus Silver transported to Moebius with Rob. Once there, the two hedgehogs met up with Sonic, Scourge, Amy, Rosy Rascal, Metal Sonic and Shadow the Hedgehog. During the brawl, when Silver threatened to kill Sonic, Rob targeted him with his bow and arrow and demanded an explanation. Silver then expalined that someone betrayed the Freedom Fighters, thus dooming the future, and that it was most likely Sonic due to his power. Following this, Rob teamed up with everyone else to take down Scourge. Scourge, refusing to give up, used the Anarchy Beryl in his throne to transform into Super Scourge.

After Super Scourge's transformation, Rob worked with all the Freedom Fighters and the Suppression Squad to try defeat him. His efforts failed, however, but Sonic was still able to outsmart and defeat Scourge. Rob later returned home.
