Story

The citizens of Mobius just can't seem to catch a break. Dr. Robotnik (AKA Eggman) is yet again up to his no good tricks. Factories and pollution are spreading like wildfire as he's once again trying to take over the world. Fortunately, the Sonic Heroes are never at rest, and once again wage their battle to defeat Eggman's evil forces.

However, the heroes have landed in double jeopardy. Eggman's madman descendant, Eggman Nega, has escaped from the Ifrit's dimension, and is wreaking his usual havoc in an effort to destroy the world. He's even captured Eggman's top three lieutenants, the ruthless Team Metallix, and reprogrammed them to do his even more evil bidding.

Unlike previous instances of Nega's destruction, Eggman is not fazed. He figures that once he's in control of the world, he can take care of Eggman Nega as he pleases. Unfortunately for Eggman, Sonic the Hedgehog isn't having that. Before he can decide who to dispatch where, he receives a call through the communicator Tails gave him. The message: someone's already on the case. Not just someone, but someones!

Apparently, Sonic's very own sister, Sonia the Hedgehog has already caught wind of Nega's evil and is out to stop him. Sonic is a bit eased, knowing full well of his sister's strength and agility. She also lets him know that she has found and teamed up with a mysterious young hedgehog who can move things with his mind. Sonic instantly recognizes that Sonia is with his newest ally: Silver the Hedgehog. Silver has once again traveled through time to ensure that the future is free of Nega's tampering (though he really ought to just stay here in the present, you know). Knowing that the two hedgehogs are more than capable of handling the situation, Sonic leaves it to them, and resumes dealing with Eggman.

Eggman Nega is well aware that Sonic is busy with his dimwitted ancestor. However, he'd do best not to overlook a certain factor. The S Factor, Sonia and Silver! It's up to you to lead the unlikely tag team of the physically powerful Sonia, and the psychokinetic Silver on their quest to right the wrongs of the evil Eggman Nega!

Characters

SFSA.png

Sonia the Hedgehog

The older sister of the world famous hero, Sonic the Hedgehog. While she doesn't have his super speed, she makes up for it with quick moves, and incredible strength. Though she tends to be quite high maintenance, and a bit bossy, Sonia is incredibly agile, and a capable fighter to boot. She has a special move called the Super Twirl that allows her to accelerate into a powerful cyclone.

Silver the Hedgehog

One of the newest recruits to the Sonic Heroes, Silver is from a world in the distant future. Because of his strong determination to uphold the ways of truth and justice, Silver often finds himself chasing the time and dimension hopping Eggman Nega. Silver's most powerful asset is his mind. He wields amazing psychokinetic ability! He can move nearly anything, even himself, by just thinking about it! It is this trait that gives him his unusual flight abilities.

Eggman Nega

Rush eggman nega.png

Eggman's evil descendant from the same time period as Silver. Rejected by scientists because his ancestor's failures, Eggman Nega traveled back in time and tried to replace him and gain honor to the Robotnik name. His plans were thwarted, and now he wants revenge. If he can't rule the world, he'll simply destroy it and find somewhere else to rule. Nega's presence usually requires Sonic's and Eggman's troops to team up, but Eggman has different ideas this time. Can Sonia and Silver stop his plans for world destruction?



Team Metallix

Dr. Eggman's top henchbots have been reprogrammed by Eggman Nega and attack our heroes in the White Blaster Zone!

Metal Knuckles
