Silver the Hedgehog

Silver the Hedgehog is a hedgehog from an alternate future. Going back in time to Mobius Prime to seek out Sonic the Hedgehog, who he suspected betrayed the Knothole Freedom Fighters in his own timeline, Silver eventually found himself on Anti Mobius and ended up part of a large battle between hedgehogs as he tried to identify Sonic among them. After witnessing Sonic's good nature and Rob O' the Hedge explaining that the evidence Silver had was circumstantial, Silver returned to his own timeline to do further investigation. Silver returned to Mobius thirty years later in the Mobius: X Years Later dimension just in time to save King Sonic and his family from being assinated by a missile attack from Lien-Da.

Search for Sonic the Hedgehog
Silver appeared for the first time on Mobius Prime over Never Lake in Mercia, to the surprised Rob O' the Hedge and his wife Mari-An. Silver first believed Rob to be Sonic due to their similar appearance, but when Rob explained he wasn't him, Silver told him he needed to find this Sonic as the future depended on it. (StH: #194)

Rob O' the Hedge explained to Silver they could find Sonic at Freedom HQ. Using Silver's super Warp Ring, the two travelled there together. Silver and Rob arrived together to find Sally and Alicia arguing about stranding Sonic and Amy Rose on Moebius. After getting the gist of the situation from Sally, Silver wasted no time transporting himself and Rob to Moebius. Once there, the two hedgehogs met up with Sonic, Scourge, Amy, Rosy the Rascal, Metal Sonic and Shadow the Hedgehog. (StH: #195)

During the ensuing fight, Silver attempted to discover which hedgehog among the group was Sonic, gingerly attempting to ask the individual combatants. Getting increasingly annoyed by everyone ignoring him, Silver halted everyone with his psychic powers and demanded Sonic's identity, to which both Sonic and Scourge replied "He is!" Deducing the truth from the blue Metal Sonic, Silver attacked Sonic, only for Rob to demand he stand down. Silver protested, explaining that in his future someone betrayed the Freedom Fighters and he figured only Sonic was likely enough to have the power to do that. But Rob argued otherwise, displaying Sonic's heroism and giving Silver reason for doubt. Scourge then jumped in and attacked both of them, taunting that Silver should use his powers to give himself "a less-stupid haircut". Shortly afterward, Sonic made a proposal to everyone to stop attacking each other and strictly finish off Scourge. In response, Scourge used the Anarchy Beryl in his throne to transform into Super Scourge. (StH: #195)

Silver tried to defeat Super Scourge but was temporarily knocked aside like all the others. Shortly afterwards when Super Scourge tried to defeat the Suppression Squad and Freedom Fighters after they came through the Star Posts from Mobius, Silver used his psychokinesis to grab and hold Scourge before he could injure the cowering Miles, but Super Scourge managed to break free. Silver tried this again on Sally's orders so the others could pile on top of Super Scourge long enough for him to lose his super form, but Silver's power failed him yet again and Scourge threw the others off of him. Scourge was eventually stopped thanks to the quick thinking of Sonic, as the Anarchy Beryl drained Scourge of his strength when he powered down. Following this, Silver walked back with the others to Dr. Kintobor's tower and told Sonic that he would do more research concerning the betrayal of the Freedom Fighters and return one day, then departed to his home time via Warp Ring.

Return 30 Years Later
Silver kept his promise and found his way into the Mobius: X Years Later dimension, thirty years after his first encounter with Sonic. During the celebration for King Sonic and Queen Sally, the Dark Presence's leader, Lien-Da fired a missile at the royal family. Before the missile could destroy the king and queen along with their children, however, Silver arrived just in time and used his telekinesis to destroy the missile and save them all, telling King Sonic that he returned to attempt to save his future once again.

Personality
Silver has a strong sense of justice and it is this personality trait that motivates him to head back into the past to correct the future to help his people at whatever the cost. However, this eagerness to do good is coupled with a strong naivety; he often jumps to conclusions and readily believes anything he's told. Thus he is prone to manipulation and making poor decisions; he often benefits from having someone to assist and guide him in his actions. While determined to do the right thing, he lacks ruthlessness and sometimes has trouble figuring out the best way to attain his goals. He's also noticeably shy and somewhat polite as seen during the battle when he tried asking around which one of them was Sonic and only resorted to getting rough when he was ignored and got annoyed. (StH: #195)

Abilities
Silver's main power is his psychokinesis, which allows him to lift, throw, hold and move objects (and people) easily with a thought, though repeated and extreme use can cause strain. While he has his limits, he can often affect multiple targets at once. He can also disable some machines, and by manipulating his powers around himself, he can hover. Silver can also capture objects in an orb of psychonkinesis and crush them while inside and not let anything get out, like he did with the missile fired at King Sonic and his family.

Background information

 * When Silver was first introduced into the game universe in Sonic the Hedgehog (2006), it was in a similar way to the comics. He went back in time to kill Sonic because he would cause the destruction of his world as the Iblis Trigger. This was later proven false just like the comics.
 * Which, in a way, also happened in the comics. As Ian Flynn stated that he is "treating it [the comic] as if Sonic06 already happened. Since its story effectively makes itself never happen, I'm saying that it did happen in the book - which is to say it didn't."

Possible Descendant

 * Some fans have speculated that Silver could possibly be the descendant of Sonic, Shadow, Amy or another famous hedgehog, but this has not been confirmed. Evidence to support this theory for the game universe appeared in Sonic and the Black Knight, where Silver is depicted as Sir Galahad, the son of Sir Lancelot who was played by Shadow the Hedgehog, indicating a possible hint at Silver's heritage.
 * When writer Ian Flynn was asked if he was going to reveal who Silver was descended from, he said "No." He went on to further explain that he is "not touching or even hinting at that in fear of Sega will make it official and make [him] look stupid. That said, [he doesn't] think Sega will ever delve into Silver's back-story. Short of cameo appearances or non-main-series games, [he] think[s] we've seen the last of him. All that said, [he's] sure [Silver] ' ll remain a familiar face. And given how much SegaSonic parallels Dragon Ball Z, [he]'d wager Silver is somehow descended from Shadow and Amy. He also said that people should not ask him "how that'd work", and that he was "just going off the patterns."
