Dr. Eggman and Dr. Wily are making finishing touches to their Egg-Wily Machine X at the Weapons Lab. Wily is commenting to do slow, even strokes on the horn, as he doesn't wish to use a sloppy machine in a victorious battle, while Eggman, spraying the Egg-Wily Machine X while on a harness, commented that he offered to simply allow a Badnik to complete the machine, but Wily refused as he wanted a "craftsman's touch" on the machine in irritation. Various crashing sounds are heard in the room, many of which were from Sonic and Mega Man's battle with Metal Sonic and Bass, respectively. Wily then commented that Duo and Chaos Devil's battle is causing even more destruction than the blue heroes and their last line of defense, where he mentions that should the Genesis Wave Generator is disrupted, all will be for naught. Eggman then commented that its even worse than that: it might resulted in their home universes collapsing, and also told Wily to focus as when the machine is completed, nothing will stop them. Wily commented that he wasn't wild about the name Eggman gave to the machine, with Eggman retorting that the name fits because the "Egg" prefix was used for his machines, Wily's machines were using the "Wily Machine" designation, and the X puts it together. Wily then remarks that they just finish the machine. Privately, however, Wily also reiterates that he also means "finish" as in offing Eggman as he realizes that Eggman is far too dangerous to cooperate with. Eggman likewise feels its getting closer to offing Wily as well.
Meanwhile, Mega Man and Bass are engaging in a firefight against each other while Sonic and Metal Sonic are fighting running across the walls to fight each other in the Wily Egg's antechamber. Sonic then dodges a blow from Metal Sonic and then commented on their prior fights and tells the robot that it can't beat him. However, Metal Sonic threw an object at Sonic, knocking him off, although they then stop and then rush at each other, with Sonic commenting that Metal Sonic's prior action was a cheap shot by a cheap copy. Meanwhile, Bass continues to blast at Mega Man while Treble attacks him head on. Mega Man manages to strike the robot wolf, enraging Bass, only for Sonic to get blasted and land injured nearby.
The two heroes quickly realize that they're being delayed by their rivals, and Sonic proposes "the ol' 'mix and match' plan"; agreeing, Mega Man goes after Metal Sonic while Sonic takes on Bass. Unfortunately, the plan proves flawed, as Bass' rapid fire tactics and Treble's attacks prevent Sonic from getting out his favored banter, and a kick from Bass sends him flying. Mega Man finds himself similarly overmatched, struggling to land a hit on Metal Sonic, and having his one successfully aimed attack blocked by Metal Sonic's Black Shield. Metal Sonic quickly throws Mega Man against a large metal box in the room, where Sonic joins him. Realizing the plan's faultiness, Sonic proposes another strategy: focusing their combined efforts on one opponent before turning their attention to the other one, and employing all the weapons Mega Man acquired from defeating the Roboticized Masters. A game of rock-paper-scissors determines Bass as their first target, and Sonic attacks him and Treble while Mega Man equips Shadow Man's Chaos Cannon ability, calling upon Shadow's Chaos Control power to freeze Bass and allow Sonic to strike at him again.
Treble comes after Mega Man himself, and the Blue Bomber calls upon Silver Man's Psycho Burst, turning Silver's psychokinesis upon the robotic wolf before turning it on Bass as well. Sonic then delivers a heavy blow to Bass, while Metal Sonic-who had previously attempted to hit the two heroes only to embed himself in the crate they were hiding behind-goes after Mega Man. Caught between him and Treble, Mega Man activates Espio Man's Chroma Camo, and with all of Espio's stealth dodges out from between the two. He then equips Vector Man's Acoustic Blaster and turns Vector's fury on Bass, allowing Sonic to strike again. Calling upon Rose Woman's Piko Hammer, Mega Man then strikes Bass a final blow with all of Amy's ferocity. With Bass out, the pair turn their efforts on Metal Sonic, Mega Man calling upon Tails Man's Tails Wind to stun him. Sonic delivers another blow to his robot enemy, and Mega Man follows up with Knuckles Man's Sharp Knuckles ability, striking Metal Sonic with a Knuckles-style punch. Still in fighting shape, Metal Sonic rams Mega Man head on, only for Mega Man to use the Rapid Stinger ability he acquired from Charmy Man to strike at Metal Sonic. Sonic then finishes the job with a Spin-Dash attack, leaving all three of their enemies too badly injured to continue.
Weary but undeterred, the two heroes decide to face the doctors, only for the Egg-Wily Machine X to smash through the wall and easily overpower both weakened heroes. Shortly thereafter, they awaken to find themselves in containment pods, facing the gloating doctors. Spotting the Chaos Emeralds nearby, Mega Man asks about them, prompting the doctors to launch into a brief rant that leads them to behave much as they did upon first teaming up-until they remember their growing antagonism. Sonic and Mega Man then reason that the doctors tricked them into pursuing the Roboticized Masters in order to give them time to finish their scheme, though the pair admit that their proposed contest was entirely genuine. However, their real plan has now been realized: preparing an even more powerful version of the Genesis Wave. Mega Man is quick to question why they would need another wave after their success in altering both Mobius and Earth 20XX, and the doctors inform him of the limits of their previous reality-altering attempt. They then announce their ultimate plan: to completely rewrite their universes using the power of the Emeralds, allowing them to become virtual gods. Furthermore, they intend to erase their enemies from reality, leaving no further opposition to their plan, which horrifies the pair of heroes. Meanwhile, outside the Wily Egg, the pair's battered allies-including Dr. Light, Charmy, Proto Man, Blaze, Rush, Tails, and Rouge-stand surrounded by the Robot Masters.
