I'm working on Marvel's Spider-Man in American comics.

Chapter 637 The Monster That Destroyed Asgard
Rewind to a longer period of time, after the failed attempt to defeat Thor, Loki returned to his body, but he didn't seem upset, just looking around with boredom.

After a while, he heard footsteps. At first, he thought it was Thor's visitor, so he stood up and turned his back. After a while, he turned back and looked at the person in front of him, because it was not Thor.

The person who came was Odin.

Odin donned his armor and helmet, and stood before Loki, spear in hand. Loki, after a moment's thought, knew this wasn't an execution, and couldn't help but laugh: "What's going on? Is the Great Allfather embarking on a campaign?"

"Ragnarok... When I sacrificed my right eye to Milton, hoping to see the future of the Asgardians, I saw Ragnarok, my child."

"Everyone knows about this, old man."

"What they didn't know was that I didn't see Ragnarok itself. I saw a group of people who had no color and no voice, but they could speak to me. They showed me everything about Ragnarok: Baldr was killed by mistletoe, Fimbulwinter came, the armies of the Nine Realms attacked Asgard, everyone died, and then Asgard was destroyed."

"A group of...gods showed you the future?"

“They showed me the past, son. They showed me Asgard’s endless cycles over hundreds of millions of years. Ragnarok was not a prophecy, but just their game. They sat there watching us die over and over again. They seemed to… feed on it.”

Loki's expression changed, and he walked up to Odin in disbelief: "You never said any of this."

"What good will it do to say all this? To tell the Asgardians that they are nothing more than a meal, or to tell you that Asgard was never a great god and we are just puppets?"

Odin sighed deeply: "I did a lot of work to avoid Ragnarok—Baldr was not killed by mistletoe, and you were adopted by me and became my son. If my previous prediction is correct, you will return to Jotunheim and become the Frost Giants King, while Thor will inherit Asgard, and there will be no more war."

"Then why didn't you let me go back?"

Odin looked at Loki and asked, "Do you want to go to Jotunheim, son?"

Loki didn't answer; he laughed. He suddenly understood many things, so he sat down on the ground by himself, and Odin followed suit, sitting down fully armored.

“You need Jotunheim to have a qualified, even excellent, monarch, and a close brotherhood with the future monarch of Asgard. So you gave me and Thor the same treatment and education as heirs, better than Tyr, Baldr, and Heimdall, making everyone think that you were going to choose one of us as your son. But when I grew up, and you could kill Laufey at any time, you were unwilling to do it.”

Because a father didn't want his son to leave.

"Fool, this is all so stupid! All of this has been ruined by your emotions! You are the Father of the Gods, you are the King of Kings, you...!"

Loki was speechless for a moment, but then, looking at his father who was staring at him with confusion, he suddenly realized something was wrong and stood up: "Why are you telling me all this? What are you going to do to go to war?"

“Heimdall saw what Malekith told you. In fact, he was much more proactive than you. The Wild Hunt can move freely through the Nine Realms without the help of the Rainbow Bridge or Norn Stones. He came to Asgard a long time ago, trying to find my past enemies and find a way to defeat me.”

"What's there to fear about your defeated foe? And the enemy you fear, doesn't Malekith fear as well?" "...I have a theory. No matter what I do, the Shadow Gods will choose to interfere. I don't know who they are, but I know they have the ability. For example, I once destroyed an incredibly weak civilization. I've forgotten why, perhaps because they blocked Asgard's expansion, perhaps because they offended me? Perhaps for some other reason. In any case, I wiped out their entire race, billions of people."

“I’m not saying I regret it. After all, I did many similar things during the conquest of the universe in Asgard, but this time, something is different.”

"The resentment of billions of people of that race coalesced into a materialized demon. He may very well be an abstract entity of the concept of 'hatred' in the entire universe. As long as he comes into contact with hatred, he can strengthen himself. As long as there is hatred, he can grow infinitely. As long as hatred exists in the universe, he can be resurrected continuously."

Odin spoke calmly, as if he were talking about something very mundane, but Loki was terrified and broke out in a cold sweat: "You've done this kind of thing so many times, and suddenly this monster appears?"

"It makes no sense, right? I think it makes no sense either."

"So how did you defeat that monster?"

“No, I took control of him right after he was born, before he had fully processed all the memories of that race, and then locked him up underground in Asgard. For hundreds of thousands of years, he has been filled with hatred, and thus he has become stronger and stronger.”

The entire Asgard suddenly began to shake violently. Loki looked around in horror, not knowing what was happening.

Odin stood up as he spoke: “I’m not entirely sure how Malekith knew about him. Perhaps he found out some inside information, or he got help from the Norns. In any case, just now, the troll king Ulik announced his rebellion, and his troll miners found the prison in advance. The monster has already come out, child.”

Odin removed the prison's defenses, letting Loki do whatever he wanted, but the surrounding tremors grew stronger and stronger. Even during Odin's slumber, when the demons and monsters of the Nine Realms invaded, Asgard had never been so turbulent.

Loki saw Odin turn to leave and quickly followed, using magic to conjure his own helmet and put on his dagger.

He stepped out of the cell and saw only smoke and fire. In an instant, his brother Heimdall was thrown several kilometers away, crashing into a building that had collapsed. Then, a golden monster roared Odin's name and leaped toward him.

Odin!!!!

Odin roared the monster's name in return and hurled the Eternal Spear at it.

"Mangogo!"

　catching up on yesterday's update

　　Mangog's role among Thor's villains is roughly equivalent to Doomsday in Superman's story—both are immortal, grow stronger with each passing year, and relentlessly target their opponents.

　　Incidentally, the place where Mangog is imprisoned in the comics is Nornheim.
