The rumblings grew louder as all of Canterlot nervously began to wonder what was happening around them. With the invaders drawing back, those who were still willing to fight realized that he was coming to finish the job.

"Everyone on my position," Steve said into his radio. "We have incoming."

"What the hell?" whispered Natasha.

Suddenly, the vortex appeared and much to the shock and the horror of all, Emperor Grogar came through the vortex and right through the gates of Canterlot. Knowing that he was there for them, Celestia realized that there was only one option.

"We have to surrender our magic," she said to Luna and Cadence as they retreated into Canterlot Castle by teleporting. "It's too late now."

"Sister, we can't," cried Luna.

"We don't have a choice. Grogar is here and he has the elements."

"What?!" gasped Cadence her voice filled with horror. "But Twilight…"

"…has fallen and there is no other way to get ourselves out of this."

"Can't we do something?" Luna asked again, but Celestia silently shook her head sideways, meaning that there was no other option. The Princess of the Night realized that there was no other option nor any other choice. They had to surrender.

Still, the remaining defenders were going to do whatever it took to protect the three remaining alicorns.

"Eyes up, stay sharp," Steve ordered as he once again activated his shield with Tempest following suit. Grogar readied the Chaos Gauntlet to easily take out anyone who stood in his way.

Starlight Glimmer in the Hulkbuster armor was the first to try defending the princesses, but Grogar used the Element of Generosity to encase her inside a wall. Steve was the next to try, running towards Grogar only to be blown back by the element of kindness. Black Panther leapt up into the air, only for Grogar to catch him using the element of laughter. Clutching his throat, Grogar threw a punch to Black Panther's face, knocking him out cold. Falcon, Rainbow Dash, Sky Stinger and Vapor Trail all fired barrages of missiles at Grogar, but they were knocked out of the sky and all landed hard on the ground below.

From inside the castle, the three alicorns each realized that their options were severely limited.

"There is a way we can protect our magic," Celestia said firmly.

"How?"

"We give it up and send it to Twilight."

"But, she might be dead or worse!"

"There is no other choice, Luna!" Celestia retorted firmly with tears forming in her eyes. "We have to try! No matter what happens, I love you both with all my heart!"

Accepting their fate, they all formed a triangle around each other and attempted to rid themselves of their magic.

Meanwhile, the vain effort to defend the princesses continued. War Machine was the next to try and Grogar used the element of loyalty to tighten his grasp on War Machine's armor, throwing him into a building. Rocket Raccoon and Bucky ran towards Grogar with firing guns, but were both knocked back by the element of generosity. Spider Woman and Black Widow were the next to try, only to be encased the Element of Laughter's powers. Groot used his vines to try and encase Grogar in them, but he too, was unsuccessful in his actions.

Now, Tempest ran towards Grogar and quickly casted a shield spell to stop him. The broken horned unicorn let out a loud yell as she felt the pressures of Grogar's acquired powers get to her. Unfortunately, like all the others, Tempest fell to the ground. Now, only Trixie and Scarlet Witch stood in his way.

"What do we do?" Trixie cried to Wanda. "We're the only ones in his way!"

As she spoke, Starswirl, Rockhoof and Flash Magnus also tried to take on Grogar only to be flown back using the element of magic. Somanmbula, Mistmane and Mage Meadowbrook were the next to feel Grogar's wrath.

"We hold him back as much as we can," Wanda said firmly as she looked back to see the alicorn princesses removing their magic. Activating their powers, Wanda and Trixie fired blasts of magic to try and hold off Grogar from reaching the princesses. Sensing what was happening, Celestia urged Luna and Cadence to further hasten the process. A few moments later, a blast of white magic filled the castle and spread out across Canterlot.

For the next few minutes, a tense silence filled the city as Trixie and Wanda looked up at Grogar with worried eyes. Then, they turned around and opened the door, seeing Celestia, Luna and Cadence collapsed on the floor, with their magic out of them.

"Are they…?" Trixie cried, tears forming at the corners of her eyes.

"I understand, my children," Grogar remarked, knowing that he had one final card he needed to play. Both Trixie and Wanda each gave Grogar a disappointing glance.

"You could never," hissed Wanda.

"I know what it is like to lose," Grogar whispered, stroking Trixie's mane with his hoof. "But now is no time to mourn. Now, is no time at all."

Smiling, Grogar activated the element of magic and remembering the very same situation that ended the life of her beloved, Wanda realized what was about to happen as the three alicorns each regained their magic.

"NO!" screamed Wanda and Trixie only to be sent flying back by Grogar as he swung his bell around and began to painfully drain the magic out of the three alicorns. Screaming loudly in pain, Celestia, Luna and Cadence each felt their magic being drained out of them at a fast pace.

Soon, they were fully drained and tossed to the floor like ragdolls.

Feeling the energy circulating through him, Grogar roared loudly in triumph of his conquest. Suddenly, he felt a powerful blast strike him in the back and he looked up to see Thor flying towards him with his hammer fully charged. Shining Armor also followed suit and seeing his wife lying down on the ground, he raced over to her while Thor threw himself onto Grogar. Pushing him back against the wall, Thor looked at Grogar with an intent to kill.

"I told you a long time ago," Thor whispered. "That you would die for that."

And Thor dug his hammer into Grogar's chest, causing him to scream loudly. Finally, he could only produce labored breaths knowing that if he needed to carry out his plan, he needed to do it now.

"You…" he gasped, weakly looking at Thor. "…you should have gone for the head."

And before Thor could respond, he stamped his hoof down hard and for a brief moment, a white light of death filled Canterlot while the rest of Grogar's allies watched from a hilltop with the remanants of their forces.

"He did it," Tirek whispered. "Grogar has done it."

"Now what do we do?" asked Chrysalis.

"We sit back and watch," answered Sombra, smiling with malicious intent. "While our leader populates his kingdom."

Once the flash was gone, Thor looked down and saw that the Chaos Gauntlet was badly damaged. The elements of harmony, once the mightiest weapon in Equestria, was reduced to being cracked and unusable.

"What did you do?" Thor demanded. "What did you do?!"

Rather than answering his question, Grogar produced the portal that brought him to Canterlot and disappeared through it, leaving Thor's badly damaged hammer on the ground.

It was over, the Battle of Canterlot was over and Grogar and his evil forces had won. Very soon, the fruits of their victory would be labored…
