Avengers: War for Equestria

"I'm Dr. Stephen Strange and I have something important…in fact, of great importance, that I need to show you both."

"But…" stammered Princess Celestia, her face filled with confusion. "What…how do you know of what is to happen?"

Dr. Strange then moved his hands and formed a viewing globe in front of the two sisters. Inside the globe was burning red fires consuming a town filled with ponies and a large alicorn like creature towering over the chaos that was being caused.

"Because I've been there, Princess Celestia," answered Dr. Strange. "I have the power to go to the past, the present and the future. And from what see in the future, time is of the essence."

The two sisters were left dumbstruck as the viewing globe disappeared before their eyes.

"Grogar…is a very dangerous creature," stammered Luna. "Everything he has done is unforgivable, to his subjects even to anypony who has taken up residence in his kingdom."

"You must be frightened of him," remarked Dr. Strange.

"We are frightened of him," said Princess Celestia. "The powers he harnesses are unlike anything we have ever encountered. He is just too dangerous to be in existence, which is why we banished him and Tambeleon for 1,000 years."

As they spoke, Dr. Strange began to get the sense that there was much more to this story than met the eye. He had seen the story play out and knew that the sisters would have a sense of fear towards this story.

"As you have seen," he replied, opening a portal behind him. "It isn't just Grogar you should fear. I can see it in your eyes, I can see it when you speak. But, we can prevent this future from playing out."

"How?" asked Luna.

"The first thing you have to do is to contact Tony Stark," answered Dr. Strange, stepping into the portal. "Do your part and I will do mine."

"What part? Wait!" cried Celestia, but Dr. Strange had already disappeared before she could talk to him. "He's gone, Luna."

"Tony Stark is coming to Equestria to look at land for this new structure of his. Should we have him come sooner than planned?"

At that moment, the door knocked and a guard came through the doorway with Princess Cadence behind him.

"Princess Cadence has arrived," he said as the adopted niece of the two sisters came through the doorway.

"I came as soon as I heard," she said, trotting over to the sisters. "What's going on?"

"We just received a vision from the future," answered Celestia, hugging her niece. "Grogar has returned."

"What? Grogar?" gasped Cadence. "The demonic ruler of Tambeleon? But, I thought you both banished him!"

"Apparently, the spell that we had placed on Tambeleon had now worn off," remarked Luna. "Now, he has escaped and is recruiting all of our enemies to conquer Equestria, including King Sombra. Starswirl was attacked by some of Grogar's forces while trying to keep Sombra's horn away from them."

"Is he all right?" asked Cadence, knowing how much he meant to Twilight and her aunts. "What would you like me to do?"

"First, you must put the Crystal Empire on high alert," advised Celestia, hastily pulling out the map of Equestria. "Have your subjects be prepared to face whatever threat our enemies impose on you."

However, there was something else that Cadence was beginning to think of.

"What about Queen Chrysalis?" she asked, hastily becoming worried, knowing just how dangerous she was in nearly destroying her wedding to Shining Armor. "If she is being recruited as well…"

"We aren't sure about her," answered Celestia, placing a hoof on her niece's shoulder. "However, it is very likely that she is also being recruited."

It was apparent of Celestia that Queen Chrysalis more likely being recruited by Grogar had sent a chill down Cadence's spine.

"I don't want her going near my family again," she cried, turning away from her aunts for a brief moment as fear filled her voice. "Haven't we suffered enough because of her?"

"We will make sure that doesn't happen, Cadence," reassured Celestia. "Right now, we need to focus on getting prepared for the fight ahead. We are getting outside help, but the help can't come soon enough. Luna, send a note to our ambassador to the United States. Tell him to send Tony Stark here at once."

Nodding, Luna did as she was told and began to draft up a letter to the Equestrian Ambassador to the United States.

…

Back at S.M.I.L.E. headquarters, Tempest Shadow approached the secured building carrying the injured and semi-conscious Starswirl on her back with Grubber trailing behind. She knew the risk of still being viewed as a criminal, but she had to take that risk. Banging on the door, she tried desperately to get the attention of anyone who was within close range.

"Who goes there?" cried a guard, opening a small latch, revealing his eyes.

"Please, you've got to help me," pleaded Tempest. "Starswirl is hurt. He needs medical attention."

The guard was beginning to get suspicious, knowing that he was talking to an Equestrian war criminal.

"Is there a doctor back there?"

"What are you planning to do?"

"Please, just open the door!" pleaded Tempest, stamping her hoof down in frustration. "I've done my time and all I want is to have Starswirl get help!"

"If you let us in," suggested Grubber, much to Tempest's chagrin. "I'll cook you the best meal of your lives!"

"Indeed…" muttered the guard and shut the latch. For a moment, it seemed to Tempest and Grubber that they would be allowed inside without any trouble.

…

Then, suddenly, the doors opened to reveal a line of S.M.I.L.E's agents with their horns pointed right at Tempest and Grubber.

"I guess we aren't very much welcome," whispered Grubber, putting his hands up.

…

Captured and detained, Tempest and Grubber were taking to a holding cell while Starswirl was taken to get checked out.

"'I'll cook you the best meal of your lives,'" whispered Tempest sarcastically to Grubber. "Remind me to tell you to never use food to solve your problems."

"What else was I supposed to do?" asked Grubber, only for Tempest to let out a loud groan. "It seems like we are still going to be viewed as war criminals by these guys. At least, they aren't going to be treating us like that minister was."

"I suppose you're right," sighed Tempest, leaning back against the wall of the cell. "But, I've gotten used to it."

…

Just then, the sounds of hoofbeats were heard and the two former allies of the Storm King turned to see Fury making his way down to their cell with an important pony behind him.

"Twilight?" gasped Tempest as the Princess of Friendship and the broken horned unicorn glanced at one another.

"Tempest," sighed Twilight, looking forlorn at how Tempest was still being treated so cruelly. "I can't believe you're still being treated this way."

"We saved the most important pony in Equestria and this is how we're thanked for it," remarked Grubber as he and Tempest were let out of the cell.

"As soon as we told Princess Twilight that we were holding you two, she was insistent that you two were no longer a danger to us," said Fury. "So, let's start over. I'm Fury Swipes, head of S.M.I.L.E., Equestrian subsidiary of S.H.I.E.L.D."

"It's nice to meet you," chuckled Tempest, glad to now have been given a much better welcome. "If there is anything we can do to help you…"

"There is much to be done, Tempest," interrupted Twilight. "For one thing, we need to learn more about Grogar and what he is planning to do. At the same time, we need to also prepare for what is likely to be a major fight ahead."

"Then, we must do so at once," suggested Fury Swipes. "Follow me."

So they followed Fury out of the holding cells to prepare for the fight against Grogar.

…

Meanwhile, Tony Stark and his girlfriend, Julia Carpenter were awakened by the sounds of a telephone ringing in their bedroom.

"Hello?" he groaned, trying to wake up.

"Anthony Stark?" asked a female voice on the other line. "This is the US Embassy in Equestria. We're calling you to inform you of a threat made not just against Equestria, but possibly the human race."

"Let the Princesses handle it," he groaned.

"I'm afraid this is too big for them and even Twilight Sparkle herself to handle it," replied the woman. "There is a letter coming to you from Princess Luna and your instructions will be listed there."

And as soon as she gave Tony the instructions, the phone went dead and as soon as the phone went dead, the door to their home produced a knocking sound.

"Middle of the night and we are already getting mail," muttered Tony, climbing out of bed and throwing on his bathrobe as he made his way downstairs. "I'm telling you, Julia, we need to start setting some boundaries here. All right, all right! I'm coming!"

Opening the door, Tony discovered that there was nobody there but a wrapped-up scroll.

"It must be from Princess Celestia herself," remarked Julia as Tony tiredly read the scroll. "And something tells me that this isn't about the new building we were planning to build in Canterlot."

Tony read the scroll and despite being woken up in the middle of the night, his eyes widened in surprise.

"Julia," he asked, hastily turning around. "Do we have anything going on tomorrow?"

"No, nothing."

"Then cancel any meetings we had planned," he said. "We're leaving for Equestria."
