The Royal 'Corrupt' Hedgehogs are a royal family made of the alternate reality counterparts of Sonic the Hedgehog, Sonia the Hedgehog and Manic the Hedgehog from an alternate dimension. Together, they are the rulers over their version of Mobius. However, their absolute rule over their planet ended up corrupting them, thus turning the siblings into cruel and arrogant tyrants, who held Mobius and its inhabitants in an iron grip. After being overthrown by their good counterparts, however, the Royal 'Corrupt' Hedgehogs realized the errors of their ways and agreed to restore their kingdom into one of peace and prosperity.


After the Oracle sent them to an alternate-dimension Mobius on a training mission, the Sonic Underground came across alternate versions of themselves that were the rulers of Mobius, but had let the power corrupt them. There was no sign of the alternate trio's version of Queen Aleena, suggesting they had ruled without supervision nor guidance or that they had eliminated her. Each is seen on a video performing cruel deeds for ridiculous reasons; Alternate Sonic was willing to destroy an entire sector of Mobotropolis for the crime of music having been heard there, the Alternate Manic was imposing taxes to the point that his subjects were living in poverty and the alternate Sonia ordered the imprisonment of not only a man who failed to prepare a diamond necklace for her on time, but his entire family as well.

The good and honorable alternate Robotnik said that the three of them hadn't set foot outside the palace in years. The Sonic Underground was brought to their world by the Oracle on a mission and were mistaken for their tyrannical counterparts by the resistance set up by the alternate Robotnik. After being captured by Good Robotnik the siblings were able to persuade him they were not their counterparts with a song. They then concocted a plan to remove their corrupted selves from a position of power, at least temporarily.

The Underground first infiltrated the palace and fired all the SWATbot guards they passed (ordering them to pass on the message and saving a cook, tailor and tax payer along the way). The three then faced off against their respective counterparts. Manic used a vehicle with a suction device (how he got it is not shown or mentioned) to first suck up the vast wealth his counterpart had accumulated, informed his counterpart who he was (at which point the corrupted Manic shouted for his guards, not knowing they had been fired) and then trapped his counterpart in the nozzle of the hose. Sonia pretended to be a reflection of her alternate self in an empty frame her counterpart had mistaken as a mirror, then scared her by shouting "BOO". After informing her confused counterpart who she was (her exact words were "I'm you, but WAY better, girlfriend"), she called her guards but to no avail. She then fainted when the Underground Manic appeared with his alternate self trapped in the machine.

Sonic then confronted his other self, eating the royal hedgehog's Chili dogs and commenting on how they were "Dee-lish". His now angry other self called for his guards, but once again they were not there. Sonic then challenged Alternate Sonic to a race across the enormous dining room table (in which he would go backwards) and almost won until his counterpart used a gun that traps its victims feet to force him to stop. He revealed he had re-hired the guards and was awaiting their return, but this was turned against him when Robotnik and his Swatbots came through instead. He attempted to escape, but was stopped when Sonic used his own gun against him.

The three were then made to see up close first hand the pathetic state of the populace and repented their selfishness, though the corrupted Manic resisted at first by saying they needed something (probably money), though he was interrupted by his Underground counterpart who said "Look with your eyes, not your mouth bud". They then hold a public gathering where Alternate Sonic claims they will be good from then on and provide luxuries such as "music and chili dogs for all". On their way home, Queen Aleena (in a vision) informed the Sonic Underground that the point of their mission had been to show Sonic and his siblings precisely what happens when power corrupts.


Though they look almost exactly like their counterparts, with no visible difference between the two Manics, Alternate Sonia wears a more quintessentially princess-like dress, and Alternate Sonic has a 'beer' belly and man breasts. Only Alternate Manic wears a magic medallion like his counterpart. Only the alternate Sonia wears a crown and royal clothes; the alternate Manic retains his vest and fanny pack, and the alternate Sonic is mostly butt naked except for his Power Sneakers and white gloves. They also have no change of height or vocal intonation with their good counterparts, and are referred to as "Prince" and "Princess" rather than "King" and "Queen".


The three siblings have personalities similar to their counterparts, albeit much darker and more self-involved. Alternate Sonic was a cruel and lazy glutton who spent most of his time eating chili dogs and not enough time running to burn away the calories; as such, he looks obese. He has ridiculously high standards of taste, firing a cook because he thought his cooking was inadequate, though his counterpart believed they were very delicious. Alternate Sonia was a vain and bossy narcissist who whines at even minor irritations, like getting pricked just one time with a pin. Alternate Manic is even more greedy than his Underground counterpart and enjoys collecting vast sums of wealth, but unlike his kleptomaniac counterpart he prefers taxing to thieving and has nothing to stand in his way as his siblings do not stop him. However, the three quickly reform themselves after learning the errors of their ways.

Powers and abilities

Alternate Manic and Alternate Sonia display no evidence of their counterparts abilities, though Alternate Sonic does possess super speed, though this is comparatively meager to the Underground Sonic's (Sonic taunts him by racing backwards and challenging him to a rematch saying he would race backwards, on one foot and with his eyes closed). However, Alternate Sonic also shows a degree of proficiency with firearms, easily hitting Sonic as he sped away with his gun.


  • It is inclined the Alternate hedgehogs are physically and psychologically weaker than their mainstream counterparts as they rely on guards and servants for almost everything, the corrupt Sonic is far slower than the Underground Sonic and the corrupt Sonia faints after seeing two Manics, apparently being unable to cope with the concept.
    • On the other hand, the corrupt Sonic shows a level of cunning beyond that of the main Sonic, cheating when the race goes wrong for him and re-hiring his guards (though he was unaware they were against him).
  • Though it is most pronounced in Sonia, the corrupt Sonic and Manic are also quite vain; the Underground first learned of their doppelgangers existence through statues of them in the palace courtyard.
  • The origins of the three are still unknown, as are the answers to many mysteries surrounding them; how they obtained the Swatbots and the location of their relatives being a few.
