Shadow the Hedgehog (Light Mobius)

King Shadow the Hedgehog (MxYL) is the Mobius: X Years Later universe counterpart of Mobius Prime's Shadow the Hedgehog.

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.

Return of King Sonic and Defeat
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 energy-fueled 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".

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.

From the Ashes
Thanks to the efforts of Lien-Da, King Shadow is broken free from suspended animation. He leads the Dark Presence on a siege of the castle. He leads Lien-Da into the catacombs were they encounter Tikhaos. Shadow planned to release her, Lien-Da objected. Shadow then destroys her armband that kept her in the timeline, in which she soon faded from existence. Shadow releases Tikhaos and gives her a large amount of Chaos energy which causes her to change into Perfect Tikhaos. However, when Perfect Tikhaos is released, the castle crumbles and Shadow appears to be buried alive as he monologues as if Maria was there.
