The Terrible Titillated Trio

Grogar snorted in annoyance as Tirek, Cozy Glow and Chrysalis simply stood around like children, not looking at each other. "You are the worst villains Equestria may have ever been cursed to endure! All of you came so close to victory, but you all ultimately failed. I'm the one who actually took over Equestria and succeeded and yet you refuse to listen to my advice and work together! You literally just saw Sombra get defeated for the second time! It's not as if you all have different goals, your plans are simple and straightforward and you all want the same thing, your objectives are aligned. You have seen with your own eyes that Twilight Sparkle only ever succeeds because she works as part of a team instead of alone! If you truly want to conquer Equestria then you must all learn to work together! Have I made myself clear?!"

Chrysalis huffed and said "I am Queen of the changelings, I have no need for such an alliance, I am already a monarch in my own right!"

Grogar deadpanned and said "You were overthrown and now spend your spare time talking to pieces of wood"

Chrysalis practically hissed as she said "That changes nothing!"

Tirek similarly crossed his arms and said "I too am opposed to this ridiculous suggestion, I can consume magic in it's purest form and am a lord on top of that, you can't force me to team up with a shape-shifting insect creature and a child with a princess complex!"

Cozy Glow also chipped in with "Well golly! It sure does seem like these two aren't going to work together well huh? Also, I am only a child, so teaming up with these big villains seems pretty dangerous wouldn't you say? I'm not sure I could do it".

Grogar became extremely annoyed and said "Very well! Only I have the power to release you from these caverns, but I could easily send you all to Tartarus where you belong, so if it takes a thousand years I want you all to stay here and learn to cooperate!" Then in a big gust of smoke, Grogar had disappeared into thin air to leave the trio to come to some sort of agreement.
