The Returning Captain Marvel

"Why don't we ask why we failed in other timelines?" Tony changed the subject.

Doctor Strange shook his head.

"Can't you say?" the Hulk asked.

"It means it won't work if you say it." Parallel Tony understood immediately. "Our universe's Strange was like that when he was talking nonsense with me."

"Let me do it." Star-Lord lowered his voice and made a tragic gesture. "Although it would mean merging with a man, I am willing to sacrifice myself for Gamora and for half the universe."

"We should refuse," Doctor Strange said.

"In other words," Doctor Banner skin wasn't green in this universe and who wasn't always in Doc Green, guessed, "We rejected him in all successful timelines."

"All of them," Doctor Strange admitted. "Because of the Sorcerer Supreme, I cannot see any future for the three options we have chosen."

"I still believe in the Sorcerer Supreme," Captain America said. "Of the three successful timelines you've seen, we should combine the first and second options."

The third option, Doctor Strange learning the Darkhold, was ignored by everyone.

Because the life on Earth and the Moon that they wanted to protect had migrated to the Merlin Dimension.

The Darkhold was written by Chthon.

In a parallel universe, billions of years ago, the natural life force of Earth's biosphere gave birth to a group of Elder Gods. Afterwards, they began to kill and devour each other, and some even turned into demons. Chthon was one of them.

Ultimately, it was thanks to Atem the God Atum that he escaped his own universe and was exiled to other dimensions.

And spread the concept of Dark Magic, as well as the "Darkhold," throughout the Multiverse.

To become the opposite of Vishanti, the god of White Magic (Oshtur the all-powerful, Agamotto the all-seeing, and Hoggoth the aged), the god of Dark Magic.

There's no need to risk the destruction of the universe by choosing the third option.

"Rogers," Doctor Strange sighed, "It's just gem against gem. All three successful timelines I've seen have followed this scheme."

"So we still have three left," Tony said.

"No," Parallel Captain America retorted, "There are two. Everything we do is not to send children to the battlefield."

"We should at least tell him," Captain America retorted. "He's the apprentice of the Sorcerer Supreme; you can't treat him like a child."

Parallel Captain America was surprised to find himself refuting another version of himself, saying, "He's just a prospective disciple!"

"Wait, wait," Star-Lord jumped between the two of them, "I, Star-Lord, have already taken care of things, well, and there's T'Challa too. Anyway, you don't need to worry about Harry Potter at all."

"Indeed," Doctor Strange said. "Next, we have two more things to do: help Wenwu obtain the Dragon Power and bring Captain Marvel back."

"Is this also part of the Prophecy?" Tony asked.

Doctor Strange nodded. "Shang-Chi cannot be the Inheritors to the Ten Rings. In 2,239,204 future occurrences, his failures were all due to his mistakes and defection. Although Wenwu is not a good person, he is a reliable and indispensable teammate."

Tony frowned. "But Wenwu is an Earthling, not a descendant of the Ta Lo's Dragon Blood."

"That's why we chose Shang-Chi among so many futures." Doctor Strange looked weary. "The people of Tarot Village accepted him more and rejected Wenwu. Shenron wasn't biased, but Wenwu's purpose—"

"Wait, who is this Wenwu?" Parallel Tony, somewhat displeased. "We can't say anything about the others, but we can give a detailed introduction about him, right?"

"He is a controversial key character," Doctor Strange said bluntly. "We must tell you everything about him in advance so that you won't have doubts or reservations about him at crucial moments."

"So, as expected," Tony said with a hint of smugness, "His claim that the Ten Rings are a seal on the deep gate of the Ta Lo, preventing Evil Demon from escaping, is a lie."

"That is indeed a lie." Doctor Strange nodded. "In fact, he was bewitched by the dark entity behind the stone door, believing that his wife's soul was behind the door. Of course, the soul was indeed behind the door, but it was inside the body of that dark entity."

"The Tarot Dimension is extremely special. There are two dimensional rulers, one yin and one yang, one life and one death, which complement each other."

"During prosperous times, the Tarot Dimension is even wider than the Earth."

"However, because people in the Tarot Dimension love life and hate death, they use the Dragon Power, which represents life, to cut off death, causing the natural laws of Ta Lo to lose their balance."

"The underworld, long unsatisfied, gradually manifested itself as a monstrous beast capable of spawning countless Dementor, yearning to turn the entire dimension, and even the earth, into the underworld."

"Remember, you must never let Wenwu find out about this, otherwise he might offer his neck for execution and willingly let his soul be sucked away to reunite with his wife."

"We need to eliminate him within ten minutes."

Even after starting work at Hogwarts, Captain America maintained his habit of reading and exercising. However, having some knowledge of dimensional knowledge, Captain America frowned and asked, "Won't this cause even greater imbalance?"

"Yes." Doctor Strange's expression was cold. "But this is what the people of Tarot Village, and even Shenron, crave. It will once again become the immortal realm it once was— the Immortal Realm. Most dimensions are like this, using immortality to lure beings in the material world into sacrifice."

"Having one more Ta Lo won't hurt."

"Moreover, the dragon is not like other Dimensional Demon God who crave to expand their own dimensions. It only likes to use mazes to hide itself and even the Tarot Dimension, and entertain itself behind closed doors."

"It's fine for Wenwu to obtain the Dragon Power and have immortality without needing anything from outside. He already achieved such merit through the Ten Rings and is used to it."

"Shang-Chi too aggressive will backfire; in the end, he will fall into darkness and maintain his humanity through killing."

"Let's skip this guy," Winter Soldier, finally said after a long silence. "When I go drinking, he always likes to tell me his long, gruesome story about his heartless father and miserable childhood. I feel like throwing up just hearing his name now."

"That leaves Captain Marvel." Tony said, projecting her picture as he spoke.

"Is this really Carol?" War Machine Rhodey exclaimed in surprise. "It's like Tomboy Emma Colin has turned into Emma Watson! Hmm, looks like we really have to rescue her."

Parallel Tony nodded, "Such a beautiful and capable girl can also soothe our tense nerves on the battlefield."

"This must be approved by the Sorcerer Supreme." Doctor Strange glared at the two of them. "This requires Ms. Carter's intervention, through Ms. Rosier."

"Let's go now." Captain America pressed the teleportation button on his bracelet, and he and Carter disappeared into the space station.

Outside the gates of Hogwarts.

Two figures appeared.

"Steve, Steve!" Peggy Carter shook off Captain America's hand, which was pulling her forward. "You don't just want me to go find Vader, do you?"

Captain America nodded. "We must tell Harry what the Sorcerer Supreme said before the other me or Bucky finds out."

In Charms.

The short professor, who possessed Goblin blood, was speaking eloquently.

"In the Duel Arena, having air superiority is extremely important; only by defying gravity can one pass through the air wall in the center of the Duel Arena."

"But simply flying makes you an easier target, unless you're good at close combat."

"For the form of an energy-based body, I recommend wind. Vaporization is the simplest method and suitable for most duelists."

"This can be combined very well with the Weatherproof Charm."

"I don't recommend merging with the Patronus of light or darkness, as this can easily lead to an even more extreme personality,"

"Remember, remember the three Ds! Goal, Determination, Composure! These can be used in many spells."

"Remember your goal is to vaporize your body, resolve to occupy the wind you imagine, and let the desire to enter overwhelm every smallest part of your body!"

Finally, your feet leave the ground, you leap into the air, forgetting your form!

"Now listen to my command one."

Ron was quite surprised that they were about to begin vaporizing into physical bodies so soon. "You haven't taught us how to turn back yet!"

Professor Flitwick almost couldn't catch his breath. "Because there's no need to teach you. Unlike the Animagus, life and natural phenomena like wind are too different. After a while, you will naturally be bounced back to human form."

"Won't it cause the Splinching?" Harry raised his hand, not wanting Ron to be left in an awkward situation. "It's somewhat similar to Apparition."

"Yes," Professor Flitwick said. "If Potter and Mr. Weasley had studied this like the other students, they would know that wind and space are different and would not pose a life-threatening danger. If the brain does not vaporize along with it, the lost limbs will quickly return to their original positions."

"What if only the head vaporizes?" Ron asked, his face pale. His vivid imagination had already conjured up a crimson fountain of blood spraying from the neck of the headless body onto the ceiling.

"The part of you that was vaporized actually remains in the original location of your body," Professor Flitwick said patiently. "Just like the Splinching phenomenon caused by Apparition, in the case of a normal loss of a limb, there should be a massive hemorrhage due to high blood pressure."

"Okay, if you have any questions, you can look them up in the book; the answers are all there."

"Magic is all about practice; you can only truly understand the essence of the answer by actually trying it."

"Now listen to my command one."

Knock knock—

Professor Flitwick took a deep breath and calmly said, "Please come in."

A very cheerful-looking young man walked in; it was Grant Ward.

In the original universe, he was a Level 7 agent of S.H.I.E.L.D.., but his true identity was that of Hydra spy and the adopted son of Hydra agent John Garrett.

Now that Hydra has long since disintegrated, he is just an ordinary fourth-year student at Hogwarts, beloved by his professors and classmates, a Cedric- like figure.

"It's Grant," Professor Flitwick said, a smile creeping across his face as he recognized one of his favorite students. "What is it?"

"Excuse me, sir, I must take Harry Potter away from the classroom," Ward said apologetically. "Professor Rosier asked me to take Harry to her office."

"This is none of your business, Grant," Professor Flitwick said gently. "Harry, take your bag and go with Grant."

"Goodbye, Harry!" Ralph patted Harry on the shoulder.

"Goodbye," Ron said.

One by one, the sound of 'goodbye' echoed in the room, Seamus even gave Harry an exaggerated hug.

"It's not like I'm not coming back." Harry shrugged.

Soon, he and Grant walked out of the classroom.

Ron watched them walk away, wishing he could be one of them.

An hour later.

"What? You're not coming back?" Ron was shocked.

"There's a beetle on your shoulder." Ginny, her eyes red, swatted the beetle away, trying her best to act nonchalant.

"Yes, I have to do this," Harry said, head bowed, avoiding their eyes. "For the sake of life in half the universe, I—"

Ginny's tears flowed freely, but a strange, twisted smile clung to her face. "What a foolish yet noble reason! I don't care! Why should we care about life on other planets that we could never easily understand in our lifetimes!"

"This has nothing to do with wizards, humans, or even Inhuman!"

"We have the Merlin Dimension, don't we?"

"Ginny, Ginny." Harry hugged Ginny tightly. "I have to go. I have the potential to stand up for justice and righteousness."

The same farewells were taking place in the Headmaster's Office.

Basil stroked Carol's smooth back. "Are you leaving?"

Listening to Basil's heartbeat, Carol suddenly felt a pang of reluctance. "I have to, that's what they say. Didn't you always say I'm the kind of person who would abandon my own home planet for the sake of the universe? Yes, that's me."

"The energy from the explosion of the light-speed engine created by the Tesseract in Project Pegasus caused me to mutate. I gained not only power, but also an enhanced sense of senses."

"In the silent universe, the cries of despair and the screams of pain are most prominent to me."

"The universe is full of the law of the jungle, with planets being destroyed and worlds being wiped out. Earth's situation is so bad that it can be described as a paradise on earth in Utopia."

"After losing my memories of Earth, I was more of Kree, upholding so-called justice, but in the end it turned out to be an unjust Carnage."

"I must leave, to atone for the sins I have committed, and to ensure that there will be no more piercing cries in the universe."

She said this as if she were trying to convince herself.

Golden Cosmic Energy enveloped her entire body, and it was as if the Captain Marvel of the past had returned.

"You're not required, and the future that Strange foresaw isn't everything." Basil wanted to say this, but both his big and small heads suddenly felt that Captain Marvel, Carol, was far more attractive than the little woman crawling on his body.

"Go," said Basil, "My prison awaits your return."

"My prisoner."

"Yes," Carol bowed, "My warden."

Hundreds of light-years away, Thanos's expression was grave.

"Harry Potter".

"Very good. If it weren't for Number 1, I wouldn't have known he had such potential."

Ebony Maw gave a sinister smile. "My lord, all we need to do is deny him the opportunity to unleash his potential—for example, by sending out an endless stream of bio-soldiers to keep him busy. You, my lord, only need to collect the gems."

"Tony Stark." After a moment of contemplation, Thanos said, "I must first obtain the Space Stone from him so that Harry Potter can never get close to me."

His gaze suddenly fell on the silent Cull Obsidian beside him.

The Cull Obsidian's skin began to turn purple.
