"Would the owner of a white hovercar shaped like an egg please report to the front desk? Your car has been broken into. Repeat. Would the owner of a white hovercar shaped like an egg please report to the front desk? Your car has been broken in-- wait a minute, what the heck?!" - One of Eggman's announcements during the Tropical Resort level in Sonic Colors.

"Curse you, Sonic! Not only do you foil my plans, but you foil my speeches as well! I work hard on them!" - After Sonic interrupts his gloating before the final boss fight of Sonic Colors.

"No, I want you to get me a cheeseburger and a shake!" - sarcastically answering Orbot in Sonic Colors.

"Time for a change of pace!" - During the Egg Dragoon battle in Sonic Generations.

"You're not in a position to demand ANYTHING, you nasty little pincushion! - Eggman after being confronted by Classic and Modern Sonic in Sonic Generations.

"After my most recent setback, I stumbled upon the primordial form of this Unique Creation. Which I discovered had amazing abilities, even I had never been able to master. It could erase time and space. I then had the brilliant idea to use my discovery to undo my previous defeats! In order to perfect it, I needed the help of someone as smart as I am. The only person that smart... is me!" - Eggman explaining about what happened after Sonic Colors and he need Robotnik's help to complete the Time Eater.

"It's the exact same time as when you asked earlier, and it'll be the exact same time when you ask later. THERE IS NO TIME HERE!" - Eggman when Robotnik asks him what time it is at the end of Sonic Generations.

"Don't get too self-righteous; it'll be YOUR plan pretty soon!" - Eggman telling Robotnik what he did, he will do it in the future.

"If you weren't always destroying them, I wouldn't need so many." - Eggman explaining to Sonic why he builds so many military factories in Sonic Lost World.

"I'll burn your worlds you rebellious scum! I'll destroy everything you love and make you watch!" - Eggman threatening Zavok and Zazz after they rise up against him and use his Extractor to destroy Sonic's world.

"As long as I can still strangle a Zeti, my hands are fine." - Eggman replying to Orbot after he comments on Eggman hurting his hands.
