King Robert O'Hedge, better known as Rob o' the Hedge, is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is the cousin of Amy Rose and the leader of the Mercian Freedom Fighters. Residing in Deerwood Forest outside of the former Kingdom of Mercia, Rob spent much of his adolescence combating the rule of Dr. Ivo Robotnik's sub-boss, the High Sheriff. As well as being a Freedom Fighter, Rob acted as a sentry for the city of Albion. When Knuckles the Echidna came to Mercia with the Lost Tribe of Echidnas, Rob o' the Hedge assisted Knuckles in freeing them from the High Sheriff's forces. Following this, Rob helped them locate Albion. After the death of Robotnik and the High Sheriff regaining his free will, Rob acted as Albion's eyes and ears to the events going on in the rest of the world. His role as Albion's sentry ended after it was destroyed by the Eggman Empire.
