Multiverse Battle of Hogwarts

[Author's Note: Here's the sequel to Marauder's Green Lily. I'm not sure if I want this to be a one shot or a complete story. Hopefully, all of you will like the sequel. Please review and let me know how I am doing since this is the first time for a sequel to one of my fanfics. ]

Recap from Epilogue:

Suddenly, an owl flew in and dropped a letter on Selene's lap.

"We haven't received an owl in awhile, Selene? " Tony said curiously.

"I know, Tony. I wonder if Siri and Howie got into trouble?" Selene said as she began opening the letter.

"If they did; how bad can it be? " Tony questioned.

"Who knows? " Stephen said.

Selene opened the letter while the owl helped itself to some food and water; then read:

Dear Mr. and Mrs. Stark,

I fear that you must be informed immediately and I do hope that the Sorcerer Supreme is with you because you will not believe what I am about to tell you.

"Okay, that doesn't sound good?" Tony said.

"No, it doesn't." Stephen said.

Selene continued reading:

It appears that dare I say that an alternate Tom Marvolo Riddle has appeared at Hogwarts and he says that Albus Dumbledore is the Dark Lord in his universe and murdered the Sorcerer Supreme in his universe and is coming after Dr. Strange in this universe and he also says that he plans to kidnap the Stark children. He was under Verasurm when he told us this.

Siri and Howie are with Professor Flitwick and the DADA professor; they are trying to calm the boys down.

After Selene finished reading the letter; both Tony and Stephen were shocked to hear this.

Selene looked at Tony and said, "Tony, what shall we do?"

Tony looked at Selene and said, "We are assembling the Avengers and heading to Hogwarts! I have no idea why are universe of 616 is being attacked yet again but know one is going to hurt our children!"

Selene nodded.

Stephen looked at them and said, "I'll inform the masters of what's going on."

Both Tony and Selene nodded. They watched as Stephen left.

"What is it about our family that seems to be the focus point of the villain's attack? " Tony questioned.

Selene looked at Tony and said, "I don't know, Tony. However, they do seem to focus also on our universe."

Tony sighed and said, "This almost feels like facing Thanos again."

"However, I don't think this Albus Dumbledore realizes who he is messing with because my dear husband; the magical world in our world has evolved and no longer fears muggles or technology. They use it to their advantage." Selene said.

Tony smiled at his wife and nodded.

Moments later...

"Tony, what's going on? " Steve asked curiously.

"Yeah, I mean we suddenly get the call to assemble out of no where?" Natasha said.

"Avengers, we're assembling because a threat to our universe had arised once again." Tony said.

"What do you mean, Man of Iron?" Thor asked.

"A villain from another universe threatens our universe once more; only this time the battle field is in Scottish Highlands at a school called Hogwarts. Siri and Howie are there." Tony said.

"What the hell?!" Clint said.

"Trust me, when I say that was exactly going through mine, Tony's and Dr. Strange's mind as well when we received the letter that informed us of the event getting ready to take place." Selene said.

Suddenly, T. J. and America came running into the room, "Mom? Dad? What's going on?"

Tony looked at T. J. and said, "Son, you and your sisters are going to suit up because we have been called to Hogwarts."

T. J. looked at his mother to confirm what his father was saying.

Selene looked at T. J. and nodded.

"Okay, because nobody messes with family and friends." T. J. said as went to suit up and America followed him.

Prologue

The Starks were suited up as well as the Avengers and America decided to come with them as well.

"Man and Lady of Iron, how are we getting there? " Thor questioned.

"Well, secretly after the unusual battle that happened that involved myself and my family; we meaning Selene and I decided to work on something that the kids didn't even know about." Tony stated.

"I'm guessing that's why Mom went with you to your lab a lot and Howie along with Siri was always with us? " T. J. said.

"Sort of Teej, I wanted your mother's approval of what I was designing considering it involved our expanding family." Tony said.

The Avengers were sort of confused.

"Dad, you said that you and mom were working on something big and it would surprise us once it was finished?" Sere said appearing all suited up and Spider-Man was with her.

"Sere, your father and I were wanting to work on something together for a while but certain things happened in which we couldn't at the time we couldn't. So, as soon as youband your siblings went off to school; we began planning in case something else unexpected happened. We just didn't tell anyone including you and your siblings." Selene said.

"Tony, what did you and Selene exactly get up to that even S. H. I. E. L. D. wasn't aware of?" Natasha questioned looked at Tony.

"Selene and I sort of made the lab a bit bigger and secretly had the Avengers Compound built. Of course, we managed to add a hanger to the compound. The hanger is basically like a garage for vehicles owned by or built for the Avengers but there is one that S.H.I.E.L.D would love to get their hands on." Tony said.

"This still doesn't explain anything? " Steve said.

The others nodded in agreement.

"Follow us, then and we will show you, Captain." Selene said.

The Avengers as well as the Stark Triplets followed Tony and Selene. They were stunned to see a tunnel as well as a shuttle bus in the tunnel. Then everyone got into the shuttle bus.

Inside the shuttle bus/The Avengers' Hanger...

"Mom? Dad? How did you do all of this without us knowing?" Mags asked curiously.

Both Tony and Selene just smiled.

"It's probably no use getting information out of them, Mags." Sere said.

Stephen chuckled because he knew that Tony and Selene had used both magic and technology to get their little secret project done without being detected by S. H. I. E. L. D. considering the whole Hydra hidden within the organization fiasco.

The triplets immediately turned to their grandfather with questioning looks because when he usually chuckled it could mean something.

"What?" Stephen said looking at the triplets.

"Grandpa, why do we get the feeling that you know exactly what mom and dad were up to the entire time?" T. J. questioned him.

"Perhaps, I do know. However, your parents have so much free time on their hands now that they decided to put it to good use." Stephen answered.

America was surprised that her former teacher wasn't going to tell his grandchildren anything.

"Um... Mr. Stark, what exactly is going on?" Spider-Man asked curiously.

"Well, we received a letter from the Headmistress of Hogwarts requesting our help because a variant of Tom Marvolo Riddle appeared with the most disturbing news that sort of involves Selene's past in this universe as well in his universe but somewhat different if you will." Tony said.

"WHAT?!" The triplets said in shock.

Both Tony and Selene sighed.

"Wait minute, Tony, are you saying that a variant of the man that wanted to kill your wife appeared and had disturbing news from an alternate universe?" Bruce said.

"I'm afraid so, Bruce. Both Selene and I were shocked by this news but ot it gets worse." Tony said.

"How much worse? " Clint asked.

"Well, if you recall that my wife issued a bloodline feud?" Tony said.

The Avengers nodded.

"Well, just like the battle with the variant of Rose Weasley and the ex-sorcerer. There was a variant of the man responsible for Selene being abused by her relatives. So, this variant of that man as come here for some reason and instead of Tom Riddle being the Dark Lord who killed the Potters; it is the variant of Albus Dumbledore who is the Dark Lord of evil." Tony stated.

The Avengers gasped as did the Stark Triplets and their lovers.

"Mom? Are you okay?" Sere asked concerned.

"I'll manage, Children." Selene said softly.

Tony knew that Selene wasn't really comfortable right now and so did the triplets as did Dr. Strange.

Moments later, they arrived at the hanger and exited the shuttle bus. When they exited the shuttle bus; they were completely wide eyed.

"Tony, how did you and Selene manage this? " Steve asked.

"I'm sure that you can take a wild guess, Cap." Tony said.

Steve looked at Tony in disbelief that Tony and Selene could have possibly use a combination of both technology and magic.

Selene noticed Steve's reaction and said, "You'd be surprised at how quickly Tony and I can get done when we're working together on something."

"You created a personal plane for the Avengers use only?!" Clint said in shock.

Both Selene and Tony just smiled at seeing Clint's reaction as well as the others' reaction.

"No offense to SHIELD, but I think they need their aircraft when they don't need the Avengers." Selene said.
