Scourge the Hedgehog
From Sonic Retro
Scourge the Hedgehog, originally Evil Sonic, is one of primary antagonists in the American Sonic the Hedgehog comic series, published by Archie Comics. He originally filled the "Evil Twin" cliche in the Comics before Metal Sonic's debut. Originally appearing as a mean Sonic in leather attire, Evil Sonic was retooled into "Scourge" in order to further develop him as a character.
In the Sonic the Hedgehog comic series, there is a "multi-verse" consisting of hundreds of parallel universes. The main universe is called the "Prime-verse". The universe given the most focus other than the Prime-verse is called the "Anti-verse". Here, locations and characters are literally polar opposites of the Prime versions.
On a world called "Anti Mobius", the evil Anti-Freedom Fighters wage a war against the good natured Dr. Kintobor. The original leader of the group was Evil Sonic. After a great peace on his planet, Evil Sonic killed his own father and took over that world. After several failed attempts at defeating his good twin Sonic the Hedgehog, Evil Sonic was ousted from the Anti Freedom Fighters, and left to carry on his own misadventures. These included several run-ins with the prime group, and an encounter with Sonia the Hedgehog and Manic the Hedgehog of the Sonic Underground universe.
Evil Sonic's adventures would eventually lead him to the Prime-verse again, where he was able to replace Sonic for a short time. During this period, he severely damaged Sonic's reputation, and had a penchant for hitting on every female he met. When Sonic returned, he battled Evil Sonic again, but the battle was interrupted. Evil Sonic would later make an alliance with Rouge the Bat in an attempt to steal the Master Emerald.
Evil Sonic and Rouge's alliance was cut short by their own greed, as the double crossed each other in an attempt for the Master Emerald. The two were met at the altar by Knuckles the Echidna's father Locke who began battling Rouge, deeming her the greater threat. Evil Sonic took this opportunity to go for the Emerald and attempted to transform into a Super State. He was interrupted by Locke, who attacked him and left two scars on his chest. Turned green by the power of the Master Emerald, Evil Sonic renamed himself Scourge, and declared his evil twin days were over.
After another series of battles, Scourge took Fiona Fox as his steady girlfriend and used a Warp Ring to return to his home world. In a matter of days, he conquered Anti-Mobius, and reformed it in his own image. He dubbed the planet "Moebius", and renamed the Anti-Freedom Fighters into the "Suppression Squad". He also forced them into taking new identities and being more than mere evil twins. He then led the Suppression Squad back to Mobius, with the intent of conquering it, just as he conquered his own world.
However, the Suppression Squad despised him for disrupting what they felt was the natural order of things, and made an alliance with the Freedom Fighters (sans Sonic, who was gone at the time) to overthrow him. Scourge singlehandedly defeated both teams, but was distracted by the latter to show Sonic long enough for the beaten Suppression to send him back to Moebius. Scourge swore that he would kill them for this, but had to deal with "Rosy the Rascal" (the Anti-Amy Rose) first.
Scourge is to Sonic as Eggman Nega is to Eggman. A mirror version of the "good" character without morals. Like Sonic, Scourge is arrogant and overconfident. Unlike Sonic, he is extremely selfish and excessively brutal. Scourge has been shown as willing to kill enemies for sport, and in fact has already done so in the past. Were it not for Rouge's interference, he would have killed Locke at the Emerald Altar.
Scourge is also just as harsh a speaker as he is a fighter. He is the only character in the comic series to use profanity on a near regular basis. What he's actually saying is left to the reader to figure out, as the traditional symbols (@#$%) are used in these occasions.
Scourge is just as fast as his heroic double and can use most, if nearly all of his abilities. The comic profile lists him as able to use Spin Dash, Homing Attack, Super Peelout, and other moves of Sonic's arsenal. He is also able to use Shadow's Chaos Control, though he requires a Chaos Emerald to do so. His physical strength is shown to be near the level of Shadow's.
Additionally, Scourge can reach a full Super State like Sonic can. As Super Scourge, his appearance similar to, and yet different from that of Super Sonics. While he has the same quill style and pupil color, Scourge's green fur inverts to a dark purple, and his irises turn black. The flames on his jacket are inverted, and the color of his shoes is as well. His sunshades are also inverted, going from red to light cyan. Super Scourge is said to have identical abilities to Super Sonic.
