The Guard Dog of the Eggman Empire,

An alternate timeline where Sonic and Tails never met, where Eggman began his conquest in Westside island, Tails's original home, years prior to the initial confrontation against Sonic in South Island, that kickstarted the series!! Here, Tails was already indoctrinated under Eggman's rule, turned into a fanatic, near-rabid beast of unhinged devotion, a guard dog, despite being a two-tailed fox!! With cybernetic enhancements, and YEARS of intensive conditoning, alongside Tails already being a rabid Eggman loyalist, by the time of the encounter with Sonic, Eggman had scent Tails to deal with the blue hedgehog, and Tails, was sucessful, not in killing Sonic, but in holding him back long enough, to secure the Chaos Emeralds, forcing Sonic to grab a pink hedgehog girl, named Amy Rose, and relocate to Little Planet, leaving Eggman to continue his world-conquering schemes without interuption, with Tails by his side, forcing all who dare oppose Eggman, to either retreat, submit, or be slain!!
