One night in Tirek's lair, the centaur sat on his throne. He was deep in thought about all that's happened in the last year. His partners from Nightmare Moon, Chrysalis, and Sombra failed in their attempts to destroy the Elements of Harmony as well as the Dragon King. He reflected more on the incompetence of his minions including Catrina and Grogar's betrayal with the latter being for his own desires. Well he wasn't going to have anymore of it.

Entering his chamber were several guards, with one of them speaking, "Master Tirek, we await your orders."

Tirek answered, "My partners have failed pitifully, but I will not be outdone by the same children who bested them. So it's time I put my true plan into action," He got up and paced before his guards, "First I require more magic from the ponies of Equestria, once I have enough I will steal the strength of earth ponies and the flight of pegasi. With no means of defending themselves I will take Equestria as my own. And then we'll move onto the pathetic human world! So prepare yourselves, my soldiers." he told them. The soldiers raised their spears and cheered.

Unknown to them, a figure had been watching them from the shadows, and thought to himself, 'The time has finally come. I must warn the Princesses.' he left the lair and stood outside before spreading his wings and took flight.

The next day in the human world, at the Drake Mansion, Spike and the elements of harmony were all in bed together looking like they had a great night. Suddenly the door slammed open, as Lyra and Bonbon came in, "Spike! Girls! We gotta..." Bonbon trailed off, as they saw the position the group was in.

"Dammit, I wish we could've been included last night." Lyra cursed.

Spike and the girls woke up, as the boy spoke, "Girls, it's early. And I hate mornings."

"So do I." Rainbow agreed.

"Sorry, but the Princesses are downstairs waiting for us." Bonbon explained.

"And someone else is with them." Lyra added.

"Ohmygosh!" Twilight gasped, "Come on, everyone, let's get up!" she ordered, as they got out of bed.

"Ooh, I wonder who they brought with?" Pinkie asked, excitedly, as they got dressed.

"I'm surprised we weren't briefed about this before." Sunset noted.

"Guess it was a last minute thing." Spike assumed.

After getting dressed, the group came downstairs to see Celestia and Luna sitting down. Accompanying them included Shining Armor, Cadence, Discord, Stone, Starlight, and Sunburst with Vinyl keeping them entertained.

"Good morning, everyone." Twilight greeted.

"Good morning, Twilight. And everyone else." Celestia greeted back.

Pinkie noticed all who were present, "Oh, if I had known there was going to be this many people here I would've made extra snacks." she pouted.

"What brings all of ya here?" Applejack asked.

"I'm afraid it's not good news." Cadence answered in worry.

"So what's up?" Spike inquired.

"We're afraid Tirek is on the move." Luna answered.

"What?" the girls gasped.

"Yes, my reaction too." Discord replied.

"How do you all know this?" Fluttershy wondered,

"We had a very reliable source." Shining Armor said, as the guests motioned to another who walked into the room.

They saw it was a hairy gargoyle-man. The creature bowed his head and spoke, "Elements of Harmony and Inheritor of the Dragon king's power. It is an honor to finally meet you."

"And same to you." Pinkie smiled.

"Who is this?" Spike asked.

"This Spike is Scorpan; brother of Tirek." Celestia introduced.

"This is Tirek's brother?" Rainbow asked in disbelief, while motioning to Scorpan.

"Yes. I know we don't look anything like each other. Believe me I heard that enough." Scorpan admitted.

"You helped in the first defeat of Tirek?" Twilight asked him.

"Yes. It was so long ago, but I always feel like it was yesterday." Scorpan sighed.

"I don't understand how ya could help your brother at all in what he was doing." Applejack said in confusion.

"When you've grown up with Tirek you'd see he can be very intimidating enough to not even try to go question him."

"And yet you did." Vinyl noted.

"Because I couldn't stand what we were doing anymore," Scorpan answered, "Ever since then I had been ruling our kingdom, while he remained in Tartarus. When I learned he escaped I searched constantly for his whereabouts, but found no trace of him. But when I heard he and the various other Equestrian enemies had joined forces I knew he was still up to his old tricks. I had found his lair a couple days ago and had been spying on him since then. And now he's ready to put into play his final plan."

Spike spoke up, "He told me he wanted enough magic so he can steal earth pony and pegasi abilities. Including the power and magic of the Princesses and even Discord."

Scorpan nodded in confirmation, "Correct. His power is finally strong enough for him to start collecting the energy of other creatures. If Tirek assimilates everything he will lay waste to Equestria and eventually your world."

"And there's no way this world would be able to protect themselves against Tirek if that happens." Sunburst noted.

"So we have to take down Tirek before he takes us down." Rainbow said, liking where this was going.

"And we don't have much time," Celestia feared, "Tirek will go all over Equestria to build his power up. We must stop him before he gets too powerful even for the likes of us."

Spike turned to his harem, "Well, ladies, looks like we got us a job to do."

"Eh, what else is new?" Applejack asked rhetorically.

"But this could be our biggest fight yet," Twilight noted, "If Tirek keeps getting stronger and stronger then we can't hold back at all."

"We need our full game." Sunset agreed.

"So let's get ready." Twilight said, as they left to prepare themselves.

Spike was in his room doing a few stretches, while looking at his reflection in the mirror, "Tirek is the last of the four Big Bag Villains we had to face, Bahamut." he began.

"We defeat him then all four will have finally been dealt with," Bahamut continued, "But you know it won't be easy. He is a power stealer after all. A consumer."

"No matter what he's capable of, we can't let him do as he pleases. Especially if he wants to take all of Equestria's magic." Spike told him, until he saw Twilight behind him through the mirror's reflection.

"Spike, how're you doing?" she asked.

"Twilight, I'm uh-I'm ok." he answered nervously.

Twilight smiled and walked up to him, "You don't have to hide it, Spike. I know you're scared. I am too. In fact we all are in a way. But just because we're scared doesn't mean we can't fight."

Spike nodded, "Yeah. We all got this together."

Twilight embraced Spike who hugged her back, "No matter what happens, we'll go down fighting together." she promised.

"I love you, Twilight." Spike said.

"I love you too, Spike." the Princess replied, as the two kissed.

"Ahem!"

The two parted and looked at the entrance seeing the rest of the Elements of Harmony standing in the bedroom doorway, "You're not excluding us out of this are you?" Rarity inquired.

"Oh, hey, girls!" Spike greeted sheepishly, "How long were you there?"

"Long enough." Pinkie smiled.

"We're about to take on a power consuming centaur and here you two are acting without a care in the world." Applejack told them.

"There will be plenty of time for that after we stop Tirek." Sunset added.

"But, we all could use a little motivation for the fight. So now is a good time." Fluttershy said, as the girls walked over to Spike and Twilight.

Each of the girls gave Spike a kiss while pressing their bodies into his to help him get into the groove of things. After Sunset gave Spike her kiss, the boy smiled at all seven of them, "Thank you, girls. Let's go stop horn head together." Spike said, and the girls cheered, before heading out with their allies.

They went back to the foyer to see their allies were all ready as well, "Did you give Octavia one last kiss, Stone?" Spike inquired, "You never know if you're coming back."

"Don't worry, Spike. I have no intention of dying." Stone assured him.

"Good. Because I don't either." Spike smirked.

Shining Armor spoke, "Fleur's already leading the guards to Tirek's location according to Scorpan. And Spitifire's leading the Wonderbolts there by sky."

"Where is Tirek's lair anyway?" Rainbow asked.

"In the Badlands." Scorpan answered.

"Is everypony ready?" Celestia inquired, as her subjects nodded.

"Then let's go!" Discord cheered, as a portal opened up and they went through.

Meanwhile at Tirek's lair, the centaur was assimilating magic, strength, and flight from several ponies he had captured from last night. With all he assimilated his body started increasing his size, as well as his muscles. The ponies were unable to use their magic, strength, or wings.

"Tasty." Tirek said feeling satisfied.

"My lord!" a guard called, as he entered while looking frantic.

Tirek growled at him, "What did I tell you about interrupting me while I'm feeding?!"

"My apologies, my Lord, but we've received word of Canterlot guards closing in on our territory."

"What?!" Tirek asked in shock.

"And there's sightings of pegasi ponies on their way to."

Tirek growled and punched a wall, "How could they have found us here? How?!"

"I don't know, sir. But if they're on their way we can only assume the elements of Harmony and Dragon King are not too far behind."

"I see," Tirek pondered, "Well, then let them come. I'm ready for them."

"So we're in the final phase of your plan?" the guard asked.

Tirek nodded and answered in one simple word, "Endgame."
