Razorklaw was the champion of the Cat Queen of the Mysterious Cat Country, a realm that had once been terrorized by the Knuckles Clan of Echidnas under Pachacamac. Early in the Second Robotnik War, when Angel Island descended to Mobius' surface, it landed near the Mysterious Cat Country. Razorklaw, the Queen, and other Cats arrived to investigate, and captured the Chaotix as they were exploring. Razorklaw faced Locke, a Guardian who had given his son the name of the Cats' ancient enemies, in battle to decided the freedom of the youngsters, and despite his superior size was defeated.

About two years later, Razorklaw resurfaced with Drago Wolf as the two new Grandmasters of the southern continent's Dark Egg Legion chapter complete with cybernetic limb replacements and set up base within the ancient ruins of the Knuckles Clan colony. His new position had come as a result of his defeat at Locke's hands, which had led to his banishment from the Felidae and his decision to join forces with Dr. Eggman. Together with other disgraced Felidae and Wolves who had gone missing due to Eggman's handiwork, the former warrior and his partner Drago hatched a plan to steal the Ancient Onyx, a scheme that they hoped would push their former cultures into war with one another. While she was investigating their operations Sally Acorn was cornered by the two and their forces and captured. They later imprisoned her in their control room, where Razorklaw was soon treated to his comrade's overblown ego as Drago was goaded by Sally into revealing information about their plans and history. While Drago was indecisive as to what to do with Sally, Razorklaw wanted to eliminate her immediately, leading to a clash with his partner. The two were then surprised as Felidae and Wolf Pack forces invaded the Mystic Ruins, and agreed to kill Sally in the face of their impending defeat. Big the Cat interfered with their plans, defeating Drago and grappling briefly with Razorklaw before the Grandmaster was subdued by Sonic the Hedgehog. Recognizing defeat, Razorklaw signaled a retreat to the Legion's secret bunker, leaving the Freedom Fighters and their allies with the Ancient Onyx. (StH: #213, #214)
