Shadow the Hedgehog (Light Mobius)


 * You may be looking for Shadow the Hedgehog from the Mobius Prime universe.

Shadow the Hedgehog (MxYL) is the Mobius: X Years Later universe counterpart of Shadow the Hedgehog. After the timeline was altered by King Sonic, and Sonic apparently vanished after the fall of Dr. Eggman, Shadow rose to power in Sonic's absence. Conquering all of Mobius within one year's time, he brought about unity and peace, though at the cost of brutal enforcement by the Dark Presence. He married Sally Acorn, who managed to bring some ease to his brutal leadership. Ruling for roughly two decades, his brutal rule came to an end after Lara-Su used her knowledge of Chaos Control to place him in suspended animation. However, five years later, after the Dark Presence successfully invaded Castle Mobius and drove King Sonic out, Lien-Da revived the former king from his imprisonment by using a Chaos Syphon.

Uprising and Rule of Mobius
When the timeline of the Mobius: X Years Later universe was changed, it altered events and made Shadow the ruler in Sonic's place, as the blue hero had disappeared from the scene following the end of the Second Robotnik War. Shadow then conquered Mobius, bringing peace in the form of a hard regime. Queen Sally then married him in the hopes that she could tame him, bringing a measure of relief to Mobius's people and legitimacy to Shadow's rule. During his tenure as king, Shadow made Knuckles his "legitimate" chief enforcer of both the E.S.T. and Chaotix, while making Lien-Da his informal chief enforcer as well as leader of the Dark Presence.

In 3262, Shadow relocated the world capital to the merchant city of Portal on Angel Island. By this point in time he had also turned Maria into an iconic symbol of worship. (StH: #166 SU: #5)

Defeat During the Coup
After King Sonic had returned from his excursions to the past, he was located by Tails and joined forces with him and Lara-Su to take down King Shadow. Due to his Chaos-derived reality warping abilities, Shadow was fully aware that history had been altered, and was determined to keep anyone from acting on it. Thus, Shadow had enforcer Knuckles arrest the three for "treason". (StH: #166)

Sonic and the others then escaped from Castle Mobius's dungeon thanks to Knuckles, who had only been working under Shadow to help defeat him. Shortly afterwards, Shadow found himself facing up against the aged and former King Sonic, though managed to defeat him with almost no effort, as Sonic had physically aged and grown weak while Shadow had not. Lara-Su soon joined the battle however, and after a brief fight, she used her own knowledge of Chaos Control to place King Shadow in suspended animation, joking that she didn't think her great-great-great-great-great grandchildren would have to worry about him becoming mobile again. (StH: #167)

Unfrozen
King Shadow was then imprisoned in a pod to keep check of Lara-Su's power freezing him. Five years later, Lien-Da used a Chaos Syphon to bring back Shadow's power. The Syphon overloaded the pod and Lara-Su's Chaos Control, and King Shadow was revived. (SU: #6)

Background information

 * It is currently unknown why Shadow decided to take over Mobius, as he has never showed any signs of wanting to conquer it. However, it is possible that due to Sonic's absence from the timeline, his attitude would never have changed to a more positive alignment, and thus would attempt to reshape the world as he saw fit.
 * It was hinted at that Shadow took down Eggman before becoming king. When writer Ian Flynn was asked how Eggman died in the MXYL universe, he said "Any events happening between the present and the maybe-future will be teased at best. That said, the original M25YL revealed that Knuckles vaporized Eggman and had to be stopped by Sonic. I figure the same events unfolded but with Shadow replacing Sonic." (1)
