The now-defunct British comic book company Fleetway Publications showed an immense love of implementing pop-culture references within their Sonic the Comic series during the 1990s and early 2000s. From Metal Sonic quoting the Dalek's from Doctor Who to time-travel plots inspired by Back to the Future, but by far one of Fleetway Publications' craziest moments was when Doctor Eggman was given the powers of DC Comics' galactic despot; Darkseid.
This immense power boost for the Mad Doctor occurred within a two-part mini-event titled 'Game Over' appearing in Sonic the Comic #173-#174 (by Lew Stringer, Richard Elson, Ellie de'Ville, and Andy Diggle) in which Doctor Eggman became so fed up with the constant defeats that he resolved to destroy the Blue Blur's home planet of Mobius. Doctor Eggman's attempt at planetary genocide allowed Doctor Eggman to conceive his own version of 'Anti-Life'. The same famous concept from comic book legend Jack Kirby that became Darkseid's driving goal within the DC Universe.
After Sonic the Hedgehog and the cybernetic hero; Shortfuse the Cybernik discovered a device on planet Earth that was draining the life-energy of the planet in Sonic the Comic #172, the Blue Blur suspected that his old nemesis was planning some kind of cataclysmic event. The following issue revealed that the highly evolved synthetic alien race known as the Plax had aligned themselves with Doctor Eggman to construct devices across both Mobius and Earth that would slowly siphon the life force of the two planets.
The life-force energy of the planets was being transferred to Eggman himself, slowly destroying all organic life while bequeathing the doctor with god-like power. Doctor Eggman planned to use this power to seed a new race of robotic life on the husks of the planets that acted as living slaves to the will of the Eggman Empire. Returning home to Mobius via the teleporting powers of the Ring of Eternity, Sonic the Hedgehog and his allies were quickly ambushed by the Plax. They were determined to ensure Doctor Eggman's plan came to pass as they believed their existence as synthetic creatures will mean that their ally will spare them.
However, Eggman's lab partner; Doctor Grimmer intervened in the conflict, informing both Sonic and the Plax that he didn't intend to spare anyone but himself. After psychically scanning Grimmer's mind to determine if he was telling the truth, the Plax turn on Doctor Eggman. But now imbued with immense power, he fired two omnidirectional beams of energy from his eyes that terminate every single Plax on the planet. These beams of energy were identical to Darkseid's Omega Beams in both function and aesthetics.
Sonic the Hedgehog attempted to avoid these faux Omega Beams only for his archnemesis to reveal that the life-force of the two planets had granted Doctor Eggman superhuman speed that surpassed his foe. With the help of Amy Rose and Shortfuse the Cybernik, Sonic was able to sever his connection to the machines, but it was too late. Eggman already possessed enough power to no longer require a constant power source. He began draining the life-force of Amy Rose and Tekno the Canary, turning their bodies old and decrepit.
As Mobius was slowly being turned into a hellscape, Sonic and Shortfuse devised a desperate plan to stop him from annihilating all life. As Sonic the Hedgehog distracted Eggman with his signature taunts, Shortfuse connected his cybernetic suit to the machines siphoning the life-force of Mobius and Earth. Shortfuse was able to reverse to flow of energy out of the villain's body and back to the two planets. The resulting shift in power caused Eggman to lose his god-like abilities and Mobius and Earth returned to normal.
In desperation, Eggman then tried to reactivate the machine created by the Plax, but the device overloaded and sent the power-depleted villain into another dimension known as the Dark Zone. Doctor Eggman's attempt at planetary genocide was one of his darkest plots within Fleetway Publications Sonic the Comic series, even rivaling much of his malign deeds in other Sonic the Hedgehog media. It is fitting then that chief writer; Lew Stringer used the motif of one of DC Comics' most dangerous supervillains to make the cartoonish Doctor Eggman into a truly horrifying threat.
