Scourge the Hedgehog

Evil Sonic and Rouge's next plan to lay hands on the Master Emerald appeared as though it would be similarly disastrous. Both thieves, their interest in each other obviously surpassed by their greed, planned to have the other get caught by Locke, and in the end were both found by him on the Emerald Shrine. They ended up fighting him, with Rouge taking most of the heat from the angry Guardian. Instead of assisting her, however, Evil Sonic made for the emerald itself and attempted to go Super using its energy, declaring it a birthday gift for himself. Locke intervened, striking the hedgehog with a Chaos-infused punch. However, the hedgehog soon recovered and revealed himself as having attained some transformation; bearing twin marks from Locke's attack, his fur was now green and his strength was enhanced.

Declaring himself a "real scourge" and claiming that the "evil-twin shtick" was over, he brutally beat Locke into submission. Rouge prevented him from doing more, saying that by her rules they wouldn't kill, so Scourge decided he should use his newfound power to get revenge on someone else: Sonic. Working by intuition, he invoked Chaos Control with the Master Emerald and transported both himself and Rouge to Knothole. Fueled with arrogance, he attacked both Sonic and later Shadow, after briefly helping them against the villainous Croctobot, but as the two teamed up on him be began to tire out, and he became overwhelmed when the other Freedom Fighters joined in. Taking Rouge by the arm, he fled the village with Shadow in hot pursuit. Rouge told him to teleport them back, but he replied that he couldn't without an emerald. They escaped Shadow's wrath when an unknown Warp Ring portal appeared and the two jumped through it. The Warp Ring had been sent by and led to Dr. Finitevus, who explained that he needed assistance in his coming plans.

Not long after Scourge had escaped Shadow's wrath along with Rouge, a warp ring supplied by Doctor Finitevus led the duo to an unknown location where Finitevus stood asking if they were interested in joining him in his goals. Scourge was quick to oblige so long as it involved harming Sonic in any way, shape or form. Scourge served as Finitevus' right hand man, teaming up with the Destructix on various occasions. His most scathing blow to Sonic and the others came when he revealed that he had become romantically involved with Fiona Fox, who then left with him after they briefly did battle with Sonic, Tails, and Amy Rose.

Scourge would remain on Finitevus' side despite Fiona's misgivings and his own doubts about Finitevus' plans. Fearing that Finitevus' plan might fail, he charged up his Warp Ring with energy from the Master Emerald, and was witness to Finitevus' tirade on how "corrupt" the world had become and his plan to "cleanse" (exterminate) all life in a wave of Emerald fire.

Scourge's fears reached their breaking point during the fight between Super Sonic and Enerjak. Scourge recognised that with Enerjak on the loose, nowhere on Mobius would be safe, so he convinced Fiona to leave Mobius altogether. Scourge admitted that ever since his battle with Sonic, he had been deeply considering Sonic's comments that he and Scourge weren't so different. Knowing he had changed since his transformation, Scouge resolved to find answers to who he was now, and left with Fiona through the enhanced Warp Ring, to the places he could find them. Scourge promised Fiona, however, that it would be fun.

Scourge, shocked at the realization that he and Sonic truly weren't so different, returned to Anti-Mobius, intent on distinguishing and separating everything from their Prime Mobius counterparts. Within a matter of days, Scourge took control of the entire planet, crowning himself King and making Fiona his Queen, and took back control of the Anti-Freedom Fighters, renaming and reshaping them into the Suppression Squad. Upon stealing a pair of Globe Posts, Scourge plotted, with Fiona's aid, to launch an assault and invade Freedom HQ. When the Posts were repaired and reactivated, Scourge sent the Squad ahead, who found the base's defenders surprised and unprepared. A pitched battle ensued, until Sonic returned from his duties with the Chaotix in New Megaopolis to turn the tide, only for Scourge to make his grand entrance and appear before them. Scourge then proceeded to battle Sonic, and in the midst of the battle, it was hinted he holds some unknown incentive that keeps the Squad loyal to him. Eventually the pitched battle between the two groups led the base dangerously close to collapse, forcing the Freedom Fighters to retreat, leaving Scourge victorious, though his taunting towards Sonic enraged him to the point he vowed to return for revenge.

A couple of days later, Metal Sonic, under the direct control of Dr. Eggman, arrived and told Miles he was here to see Sonic. Miles, instead, summoned Scourge to inform him Metal Sonic had arrived on the scene. Instead of leaving, Eggman had Metal Sonic attack Scourge, saying "Why pass up one uppity hedgehog for another?" As they battled, Sonic himself arrived, intent on battling Scourge and re-taking Freedom HQ on his own, as the Acorn Council opted to focus their attacks on New Megaopolis and they doubted Scourge would make his gains on Mobius as easily as on "Moebius". Scourge was manipulated by Miles into ordering the Suppression Squad to allow himself to battle Metal Sonic, but soon found himself out-matched. Sonic saved him at the last second, and offered another temporary truce. Scourge told Sonic to save his sympathy, as he was happy to bust two Sonic heads. Metal Sonic felt the same way, and Sonic found himself battling both. During the fight, Scourge offered Sonic the chance to conquer Mobius himself, and then, together, take over the Multiverse. Sonic barely stuttered in response. Soon, Eggman dispatched reinforcements to deal with both hedgehogs in the form of Metal Scourge.

The battle started up again, with the robotic duplicates quickly holding their own. Sonic asked Scourge to reconsider a truce, but instead Scourge pointed out Sonic hadn't answered his question about conquering Mobius and then the Multiverse. Sonic didn't refuse, as such, instead insisting he was too preoccupied with the present right now. Grinning evilly, Scourge took that as a "yes". As the battle amplified, Scourge's temper began to flare, refusing to give the robotic duplicates any ground when the battle began damaging Freedom HQ. Scourge also insisted to Fiona that he could handle them, when she asked if she and the Squad should step in. In the end, however, he broke down and asked the Squad for help, leading to Metal Sonic and Metal Scourge's destruction.

Not long after, Scourge sent Miles to bomb New Mobotropolis. But when Miles returned, apparently being chased by the Freedom Fighters, he and the rest of the squad, except Fiona, revealed their planned betrayal. Angry at Scourge for constantly abusing them, they attacked him alongside the Freedom Fighters. At first, Scourge and Fiona were getting the upper hand against both teams, but Sonic returned from his trip to Moebius and attacked Scourge. However, Boomer then blasted both hedgehogs and Miles threw them into the portal leading back to Moebius before it was closed. Scourge, now trapped on Moebius with Sonic and Amy, promised to get revenge on his team, but then looked in fear at his old stalker, Rosy the Rascal, who told Scourge how she had an "extra-special smash" for him.

Super Scourge emerges, having used the Anarchy Beryl in his throne to transformThe fight was interrupted when Shadow arrived by using Chaos Control. Though he was actually looking for the Special Zone, Sonic asked if he wanted to help him beat up Scourge, to which Shadow replied "sure". Metal Sonic arrived later, followed by Silver and Rob as well as Amy and Rosy. A confused Silver was unable to determine which one was Sonic, and attempted to ask the others as they fought. Because they ignored him, he got angry and impatient and captured them all with his psychic powers. Silver stated that he had come from the future to destroy Sonic, and then attacked Sonic. Rob O' threatened Silver for a explanation, and Silver stated that during this point in time one of the legendary Freedom Fighters betrays and destroys them, dooming the future. He then stated that only Sonic was remembered to have had that kind of power. However, Scourge jumped in and attacked both of them, claiming that Silver should use his powers to give himself "a less-stupid haircut". Shortly afterwards, Sonic made a proposal to everyone to stop attacking each other and strictly finish off Scourge. But Scourge didn't give up. He rushed to the throne room, followed by Sonic and Shadow. Scourge turned the tables on everyone, claiming he placed Anarchy Beryl in his throne. This managed to turn Scourge into a stronger form: Super Scourge.

Despite their efforts, the numerous hedgehogs were no match for Super Scourge, who defeated all of them. Super Scourge then proceeded to defeat the combined might of the Knothole Freedom Fighters and Suppression Squad (minus Rotor and Fiona), who had returned to Anti-Mobius expecting Scourge to be defeated. While he seemed to be unbeatable, Sonic eventually realized the Anarchy Beryl would have a different (and negative) effect on Scourge to contrast the positive effect the Chaos Emeralds had on him once the transformation ended. Luring Super Scourge away from the others, Sonic managed to stall for time until Super Scourge de-transformed. As Sonic speculated, the Anarchy Beryl drained him of what energy he had left in his normal form, leaving him vulnerable. Sonic subsequently defeated Scourge and captured him.

While Sonic was taking Scourge to the Zone Cops via the Cosmic Highway, Scourge broke loose and tried to escape, but he and Sonic were then arrested by Zone Cops Zector and Zespio for going through zones during a zone lockdown. The cops then took Sonic and Scourge to see Zonic via a Warp Ring. They arrive in a ruined No Zone and Scourge manages to escape by kicking the others out of the way and attempts to fully destroy the No Zone before moving on to Sonic's world. Sonic and the Zone Cops then meet up with Zonic and they battle Scourge. They quickly capture him thanks to Sonic's skills and Zonic's special control collar. Because of Scourge's mutation, he has now become a wild card in the "cosmic scheme of things." Scourge then said that he was "Sonic the Hedgehog at his full potential." before being taken to jail.
