The building started to groan, rust pitting the surfaces around us, the lights flickering and dying. The only light was from the skylight. He ordered his machines to attack, but nothing responded - in fact, they weren't immune from whatever was happening. Nothing was, except for the two of us. The glass above shattered and came down in pieces, the walls sagging and the ceiling collapsing around us as he frantically looked for an escape path.
Rather than continuing to decay, the building abruptly became flat as a pancake. Fortunate that there had been a skylight above us, in retrospect. Eggman uncerimoniously tumbled two stories, and I landed on my feet a short distance from him.
"All I wanted was a peaceful vacation. After all the blue spheres, I wasn't even going ot get involved." I advanced on him, drawing a luminescent white blade from nowhere. "But you had to push it. I wonder what everyone will make of this building's decay and destruction, and finding your body here?"
He attempted to bargain with me, but it fell on deaf ears. I have no interest in working for a would-be dictator. The white blade will slay anything that lives and quite permanently at that, and Eggman was no exception to that.
And after that, I fused the electronics of everything in the base, did a rapid about-face, and teleported back to my campsite, because I am going to ENJOY my vacation, and the plot can go fuck itself.
The Eggman Empire splintered under the various Egg Bosses, and were taken down pretty handily. Really, without Eggman to deal with, some of them were perfectly willing to defect, and those who weren't were dealt with pretty easily, all in all. And without Eggman around, anyone else who tried to start problems on the planet were dealt with far more easily, even if Sonic felt like there was something missing from his life without his nemesis.
And I got to relax. For the first time in quite a while.
