Silver the Hedgehog

Silver the Hedgehog is a hedgehog from the future. He was greeted by Rob O' the Hedge and his wife Mari-An at Mercia's Never Lake. Silver informed the two he needed to see Sonic the Hedgehog as his future depended on it.

Rob O' the Hedge was standing at Never Lake with his wife, Mari-An, when, to their surprise, Silver appeared and asked Rob if he was Sonic. Rob replied he was not but he knew him, to which Silver responded he needed to find Sonic as his 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 in Moebius. Sally explained to them what had happened, and thus Silver transported himself to Moebius with Rob. 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 one was Sonic, first by asking everyone. After being ignored, Silver captured everyone with his psychic powers and stated he has come to destroy Sonic, since in his future someone betrayed the Freedom Fighters and only Sonic was likely enough to have the power to do that. But Rob convinced him otherwise, saying that Sonic's heroism made it more likely that he wouldn't. Scourge then jumped in and attacked both of them, claiming 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 ran into the throne room and used the Anarchy Beryl in his throne to transform into Super Scourge. In the preview for the following issue, it shows Super Socurge hovering above the ground holding Sonic by the neck and everyone is knocked out. (StH: #195)

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 out his people at whatever the cost.

Abilities
Silver's main power is his Psychokinesis, which allows him to lift or throw people and objects tremendous distances with great force or just levitate them. He can also manipulate himself, like when he was levitating in the air over Never Lake.

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 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."
