Dr. Eggman vs. the Bad Guys! Astonishingly, Dr. Starline's managed to hold together his motley crew of criminals long enough almost to achieve his goal and see his plan to fruition. Unfortunately, when Dr. Eggman gets wind of their activities, he sets his sights on them. Will the Bad Guys stay together to scramble Eggman or will they crack? Find out in the epic conclusion of STH X MLP: It's Good To Be Bad!

At Dr. Eggman's EggNet Hub, Mimic, Venjix, Rough and Tumble, and Zavok all glare at the corned Dr. Starline.

"Do you really think you could betray us so easily, Doctor?" Zavok asked. "We have everything we want."

"Expect your hide!" Venjix exclaimed.

Time for your first field test, Tricore! Don't fail me now! Starline puts the Tricore into his glove and flies backward out of the chair much to everyone's surprise. Tumble attempts to punch Starline, only for the platypus to activate the Tricore's strength aspect and collide his fist with the skunk which ended hurting Tumble instead.

"That asshole has muscle, how is that even possible!?" Rough exclaimed.

"No matter, I will end him!" Zavok exclaimed preparing to attack.

"You have to catch me first!" Starline countered.

Zavok leaps at Starline prepared to end him, only for Starline to activate the Tricore's speed aspect and dash away before he can be grabbed.

"Now's he's fast as Sonic!?"

"No, idiot, he made a core that uses all of them, while we only use one," Venjix explained.

"You and Mimic, stay here in case he doubles back, Rough and Tumble, you're with me!" Zavok ordered and he and the skunks follow and chased after Starline.

"Makes sense, Starlame needed access to get what he wanted," Mimic theorized. "We could easily hide and ambush him."

"But wait for a second, Mimic, what if billboy had a point," Venjix wondered. "Those three are dangerous as he implies. And since you are free from him and I got my money's worth. What if we tip off Eggman? He could wipe all of them, and nobody could tattle tell of us."

"I like what you're thinking," Mimic said as he alerted Eggman. "I guess this where we part ways, Venjix, it's been fun but I've got to pay Whisper a visit."

"Yeah, and I've got a whole lot heads to collect, starling with Bon-Bon and Lyra."

The two said their goodbyes and headed out.

"Uh, Eggman, we got a problem!" Cozy said to him.

"What is it now?" Eggman complained. "We're already en route to those blue pests."

"Not according to Orbot, he found that alert was false," Cozy explained.

"False!?" Shadowforce and Chrysalis were shocked.

"And even more bad news, Zavok has loose in an Eggnet Hub."

"All squadrons form up on me! Extra thrusters! Time to rid of the Zeti forever!" Eggman said.

In the hub...

"You can't hide forever! Come out and show yourself!" Rough speeds through the hallways and yells for Starline.

With his Tricore's power state, Starline knocks Rough over and kicks him using two doses of his neurotoxin injections from his Multi-Tool Heel Spurs.

"One dose of my toxin will immobilize you, you shall see what two will do!"

"He's here! Starline's over here!" Rough alerted the others.

Starline flies upward as Zavok approaches a hallway.

"It's over, doctor, even before you were always a failure," Zavok said. "Your planning is sloppy, the discarding of his comrades needlessly cruel, with all of it compounded by your unearned sense of pride. On second thought, you have all of the qualities of Eggman."

Once Zavok leaves, Starline drops down from the ceiling while avoiding Egg-Knights.

Zavok's right. All this time, all my life, I've molded myself on Eggman. I've let his ways influence my life. Even tried to plan around his shortcomings, my methods are flawed. I let my vengeance for Zavok blind me. I was too quick to discard my assets as he cast me aside. No time for self-pity, time to cut the losses and get what I came for!

As Starline runs down the hallway, Tumble spots him.

"You! I'm gonna turn you inside out for hurting my bro!"

Tumble angrily swings at him, but Starline dodges his attack and strikes him with the Heel Spurs' neurotoxins as well, leaving both of the skunks incapacitated.

Starline enters the control room cautiously.

I've heard that Zavok told Mimic and Venjix to stay behind and guard it. But where are they? Blast, how do you spot someone who can turn invisible or a master of disguise? Or even uses your plan against you?! Eggman will be here any minute!

The platypus quickly deletes Egg Base Sigma from the registry, converts its defenses to serve him, and deletes all of the logs. Following this, he dashes out of the building.

Zavok finds the weakened skunks. Learning that Starline poisoned them, Zavok tells the skunk brothers to use their Core Gears to empower themselves and walk it off. However, Rough points out that he was out of power. Fed up, Zavok tells Rough and Tumble to stay out of his way, unimpressed with the inability to defeat one enemy. The skunks angrily point out that they were doing more work than the Zeti. The brothers slowly get back up on their feet and begin to walk, with Rough stating that they should abandon the others as they did not need a leader or a team. Tumble agrees and the two share a fist bump.

"Mimic! Search for Starline on the Security feed. Mimic! Venjix!" Zavok called for them receiving no response. "Why I'm not surprised. No matter, I will this machine to find my leads on the Deadly Six. We will rally..."

Zavok come out and play! Eggman came on the montier.

"The Cacohphonic Conch was lost within the Faceship. You have no means of subduing me."

Who said anything about subduing? You're trespassing! And trespassers will be vaporized!

"You would destroy such a crucial installment to rid of me?"

I can always rebuild. Taking you down and being out of reach of your EM powers is good for me.

"You're a fool if you think you're beyond my reach."

Zavok activates the hub's defenses while applying his powers to the signal. Several Egg Knights wielding Egg Guns and manning turrets appear outside and shoot at Eggman's Egg Hawk and Badnik Horde.

"Stop shooting with my stuff!" Eggman complained.

As Mimic drives away in Starline's truck, he looks at the battle.

"If I'm lucky they'll wipe each other out," He said.

Rough and Tumble see the ensuing battle from a distance.

"Shit... we got out there just in time!" Rough said.

"We'll sit this one out!" Tumble added.

Venjix saw the battle in personal aircraft.

"Note to self, never mess with Egg-brain's toys," He made a side note.

From another area, Starline watches the battle with a pout.

"Enough! All forces! Bring it down!" Eggman orders his Balkiries to dive-bomb the facility while he shoots at it with his Egg Hawk. The satellites are destroyed, leaving Zavok powerless against Eggman's attack. As he sees the building collapse around him, Zavok activates his Core Gear hoping to endure the collapse.

"And that's what happens when you mess with the best!" Eggman exclaimed as he and the others left the base.

However, Zavok emerges from the rubble alive and his Core Gear crumbles to pieces. He sees Eggman fly off in the distance. Zavok attempts to walk away but stumbles due to injuries from the attack. He uses his powers to control an Egg Knight to support him so that he can move. The Zeti plans to heal, survive, and find his way back to his pack and take revenge.

At Eggman's HQ...

"Even after that attack, Zavok's nowhere to be found," Shadowforce said.

"Well that's wonderful," Chrysalis said. "Something doesn't add up. Zavok can't be one behind the raids. That's not his style. And more importantly why would target the power core faculty and the EggNet Hub?"

"Good question," Cozy Glow replied. "But what we can assume is that someone is making moves on us, we don't who's behind, why are they doing and what's their next move."

At Egg Base Sigma, Starline has successfully converted the base into his central command and begins having Badniks paint over Eggman Empire decals. He also has some moving containers for his secret projects.

"Sorry, Eggman, there can be only room for one to sit on the throne of the world, and the person is me, Dr. Starline, leader of Starline Empire!"

That does it for this mini-series, Zavok will be back, but this time out for revenge.
