Doctor Droid

Doctor Droid is a giant, towering and powerful cyborg lifeform from outer space who created a large army of robots to do his bidding (Droid himself bears some resemblance to the late Dr. Robotnik). Droid and his army came to Mobius 20 years after the events of the series, and declared war on the restored Kingdom of Acorn, bombarding the restored-Mobotropolis and Droid's troops besieging the Royal Palace. Sonic, now King, remained behind to face the enemy and allow Sally, now Queen, to take their two children Sonia and Manic and retired-King Maximillian and escape in a transport pod to a far away location. Sonic most likely escaped and rejoined his family at a later time. Meanwhile, Droid and his army attacked Echidnaopolis on Angel Island, raising most of the city to the ground, in the hopes of securing the Master Emerald. However, a now-battle hardened Knuckles summoned his inherited Chaos abilities and destroyed Droid and his army.


 * Doctor Droid was supposed to be featured in the upcoming "Mobius: 20 Years Later" series in Knuckles the Echidna comics, and the character and hints of the storyline were seen in Knuckles #25 (in Locke's dream) and Sonic Super Special #11 (in Sally's vision with the Source of All), though it was cancelled after the Knuckles series was cancelled as well, in favour of "Mobius: 25 Years Later". Also it would have revealed the possible future storyline in "Sonic: In Your Face" would have been the true future of Sonic, and as such wasn't shown, as the series's writers have decided not to show the final true future of the characters until the end of the series itself.
