— Shadow's vow to the warriors in Lamarkie Village, Shadow of Time
This is the Light Mobius version of Shadow the Hedgehog who first debuts as the main antagonist of Shadowed Future, is the secondary posthumous(of sorts) antagonist of Shadowed Future: 5 Years Later, and will return as the main antagonist of Shadow of Time. He is the alternate version of Shadow from a possible future(called Light Mobius).
For the most part, King Shadow has the exact same appearance as his Prime Zone(Archie) counterpart, but wears a crown and cape. As of Shadow of Time, Shadow has three scars on his muzzle from a fight with Boulder the Lycanroc.
Unlike his Prime Zone counterpart-who has a grudging respect for the warriors-or his Sonic Boom counterpart-who outright hates the warriors but mostly leaves them alone-King Shadow hates the warriors and blatantly treats them with little respect. He is confident, arrogant, cold, and unforgiving. During his rule in Light Mobius, his subjects were oppressed and lived in fear, while the warriors lived in exile as fugitives. In the Prime Zone universe, he maintains his callous attitude, and frequently mocks and disrespects them.
In The Legend of Fox the Brave:
The Shadowed Future Arc:
Shadowed Future: Shadow destroys the warriors with help from his "Dark Presence"(reworked Dark Legion) when he drives the warriors from the Storming Base, forcing them to flee to a forest outside Portal on Angel Island, Shadow's new capital. Afterward, Shadow conquers the Four Worlds of his Zone and exerts a regime of fear and cruelty over his subjects, making the warriors fugitives, and murdering both Fox the Brave and Austin Smith when they try to fight back(Fox is shot through the chest with a Chaos Spear, Austin's chest is crushed by a single kick). He later tries to capture an Arctic fox cub named Flynn when Braveheart take him in, but the two foxes slip away. In the final battle, Shadow is defeated by Lara-Su while the warriors fight the Dark Legion, and is imprisoned.
Shadowed Future: 5 Years Later: Shadow first appears in a nightmare Braveheart has about King Sonic's Five Years of Peace Speech, in which Braveheart himself is murdered by Shadow as retribution for his past defeat. Shadow is later freed by Lien-Da after she has Braveheart's son Scrap kidnapped. Shadow heads for the trapped monster Tikhaos with Lien-Da and a terrified Scrap, but vanishes after releasing her.
Shadow of Time: Shadow will return as the main antagonist of this upcoming story. This time, he will be in the Prime Zone universe, and will threatening the warriors after harassing the Wandering Wolf Pack.
Like his other counterparts, Shadow has Chaos powers, able to use Chaos Control and teleportation, as well as using Chaos Spears as a weapon.
Shadow has super speed, and is surprisingly skilled in combat, able to hold his own against warriors who are much bigger and bulkier than he is.
Unknown, though it's possible his arrogance means that he often underestimates his enemies. Because he so blatantly disrespects the warriors and apparently does not understand the warriors' tight bonds, he commonly underestimates them, meaning he is more easily defeated by them.
Light Mobius Characters:
Shadow and Braveheart strongly hate each other, as Shadow ruthlessly murdered Braveheart's father Fox, and Shadow views Braveheart as too much like his father.
Prime Zone Characters:
Because of his murder of the Fox the Brave of his own World, Shadow has little to no respect for the Fox the Brave of the Prime Zone Universe, which Fox views as the perfect opportunity to unleash all his hatred for the black hedgehog, which he'd had to hold back after Shadow's Prime Zone counterpart was pardoned and made an honorary warrior.
Because of his murder of the Austin Smith of his own World, Shadow disrespected Austin in the Prime Zone, making the warrior's short temper flare up and give the "king" a verbal lashing.
Samson the Wolf
Shadow showed some respect to the Wandering Wolf leader, though this faded a bit when he discovered the young Wanderer Arrow was blind.
This Shadow is the only Light Mobius character to interact with characters outside his Zone.
