“I know my student will stop y-”  
BLAM!  
“…Well…crap.”

As long as Eggman doesn’t awaken a Monster of the Week, the Mane 6 are in for a challenge.

Eggman: Now that I have captured you-
 
Celestia: You’re going to monologue?
 
Eggman: How did you know I was going to do that?
 
Celestia: I’m a immortal sun goddess with the burden of 1000 years on my back. I know your kind, and I know that my faithful students will stop you.
 
Eggman: Is that so? Then congratulations! You are now my new Monster of the Week! Orbot, activate the Roboticizer! I got some ponies to visit.

If this is Dreamcast Eggman or Classic Robotnik with the Modern design then the Mane 6 are going to have their hands full.

Then she goes all molestia on him.

Eggman: Princess Celestia, you’re finally awake.  
Celestia: Where… am I? Who are you? What are you?  
Eggman: I am Doctor Ivo Robotnik, and what I am is the soon-to-be ruler of the entire universe.  
Celestia: I meant your species! You’re the first of your kind I’d seen.  
Eggman: Indeed. In that case, then I’ll present you with this bit of information before you robotization. My species is called ‘human’, but I am no ordinary human. I am a super genius with an IQ of 300!  
Celestia: Robo… what?  
Eggman: Robotization. In other words, you, Princess Celestia, are going to be my loyal servant. More importantly, you will be one of my most powerful weapons against that meddlesome hedgehog and his friends! Together, we shall obtain a power even stronger than your Elements of Harmony: The Chaos Emeralds!  
Celestia: You’ll never get away with this!  
Eggman: Is that so? That attitude of yours will change in just a few moments. Until then, farewell.

…five seconds later a sun flare turns off every single machine in the area.

Eggman: What’s the matter princess? I thought you had the power to destroy me. Yet you can’t because you are a pathetic leader. Anyways, I have deciphered your Elements of Harmony and I will turn your useless kingdom into my new empire! So it’s best to surrender because you are outwitted and outnumbered.

Ho

“Mwahahaha! I shall now explain to you my evil plan!”  
“Why would you want to do that?”  
“What?”  
“Why would you explain your plan to me? What would you gain from it?”  
“I don’t understand the question.”  
“Look, normally informations are only shared on a need-to-know basis. If you just exposed your evil scheme to me, chances are that I might be rescued by someone and spoiled your whole plot. Not to mention all the time you had wasted on standing here and idling with me. So what is the point of explaining the plan to me?”  
“Hmm…well…I’m not sured why, but I will say it anyway. Now, prepare to hear the most magnificent evil speech in the history! Mwahahaha!!!”  
“(what an idiot, I thought they said his IQ is 300)”

The things I do and the places I go when drunk.

“Sorry for that spot on the glass, princess. My cleaning team is on vacation.”  
“Nevermind that… why did you kidnap me?”  
“Because by kidnapping you and leaving a hint I’ll put your sister against Sonic, and… and… Oh God I’m so lonely! The only person who ever visits is that damn hedgehog, and it’s to fight…”  
“Um,,, there, there…”

“Try your best to escape, Princess. You can’t protect your precious kingdom from in there! Soon both the chaos emeralds, AND the elements of harmony will be in my possession! Mwahahaha!”
 
“You cannot possibly hope to harness the power of the elements of harmony, Doctor! They’ll be useless to you without the power of friendship to-”
 
“Hahaha!… I’ve already taken care of that. Once the ones in possession of the elements are here to rescue their precious pretty pony princess ruler, THEN my true plans can come to fruition! Though, don’t expect me to spoil them for you. There’s nothing you, the element barers, or that meddlesome hedgehog can do to stop me! Both worlds will soon be mine!”
 
(God, I must be really bored to write this cheesey dialogue.)

“You are aware I can break this glass, and you, like a toothpick?”
