Chapter 10- The Origins of Thor Part III: Ragnarok

"So while I was on Earth being a doctor, Loki discovered something about himself that made him very angry at father." Donald said.

"What happened?" Kara asked, realizing Donald was getting to the part he wanted to tell her about.


A year ago, Asgard

Loki stood in front of the Casket of Ancient Winters and closing his eyes, touched it and lifted it up. His skin started getting pale until there was no color on it at all.

"Stop!" Came the voice of Odin from behind him.

"Am I cursed?" Loki asked.

"No."

"What am I?" Loki then asked as he put the Casket down and turned around, revealing his pale skin before reverting to normal.

"You're my son." Odin said.

"What more than that?" Loki asked and Odin was silent as he asked, "The Casket wasn't the only thing, you took from Jotunheim that day, was it?"

"No." Odin said sadly, "In the aftermath of the battle, I went into the Temple, and I found a baby. Small for a giant's offspring, abandoned, suffering, left to die. Laufey's son."

Loki's eyes widened in horror, shock and disbelief. His entire world had been turned upside down by this revelation in a matter of seconds.

"Laufey's son..." He trailed off, absorbing the information.

"Yes." Odin said.

"Why?" Loki asked, "You were knee-deep in Jotun blood. Why would you take me?"

Odin said, "You were an innocent child."

Loki was having none of it though, "No. You took me for a purpose, what was it?"

When the Allfather didn't reply, the usually calm Loki exploded for probably the first time in many years, "TELL ME!"

If Odin had been just a man, Loki's outburst would have made him jump.

"I thought we could unite our kingdoms one day, bring about an alliance, bring about a permanent peace, - ... through you." Odin confessed regretfully as Loki looked like he was about to cry.

"What?" Loki asked in disbelief, struggling to hold back tears.

"But those plans no longer matter." Odin said.

"So I am no more than another stolen relic, locked up here until you might have use of me." Loki said as he walked closer.

"Why do you twist my words?" Odin asked in some distress.

"You could have told me what I was from the beginning." Loki pointed out, "Why didn't you?"

"You are my son." Odin said, "I wanted only to protect you from the truth."

"Why?" Loki asked, "Because I...I...I... I'm the monster that parents tell their children about at night?"

"Don't..."

"You know, it all makes sense now!" Loki said as Odin looked visibly stressed now from all that was happening, "Why you favored Thor all these years. Because no matter how much you claim to love me, you could never have a Frost Giant, sitting on the Throne of Asgard!"

The combined stress of Thor's banishment, the impending war with Jotunheim and Loki finding out the truth was too much for even the Allfather to bear. He fell to his knees and then lost consciousness.

Loki's eyes widened in horror as he realized what he had done, "Guards! Guards, please help!"

Two guards arrived to take Odin away as Loki absorbed all the information and his jealousy for Thor returned in full force. But it was replaced by something else. Something much worse and much darker. A hatred. For Odin. And Thor.


"So Loki wasn't your real brother?" Kara asked in shock.

"No." Donald said, "He was adopted by my father as a way to negotiate peace. And when he found out, it broke him and turned him into something else entirely. It turned him against us."

"You know, it's not my place to say but maybe your father should have told him right from the start." Kara said.

"You're right actually." Donald said to her surprise, "I have recently come to terms with the fact that my father was a great king but not a good father. I still love him. But he wasn't the best father to either of us."

Kara nodded as Donald decided to continue with his tale, "With my father in his Odinsleep, Loki became the ruler of Asgard. And he used the time to scheme against everyone. You see, he was the one who had brought the Jotuns into Asgard."

"What?" Kara asked in horror.

"Yes. In adulthood, he wasn't my biggest fan and he didn't want me to rule." Donald said.

"But wasn't that a bit too far?" Kara asked.

"He knew the Destroyer would kill them." Donald said, "But he truly went off the rails only after finding out the truth. And he schemed against Asgard. And against me."

"What did he do?" Kara asked.

"He brought an army of Jotuns lead by Laufey to invade Asgard." Donald revealed as Kara listened in horror, "And he tried to take care of me too."


A year ago

After dealing with the stone men, Thor had flown off to an isolated area in Norway and was contemplating what to do when he heard something behind him.

He immediately turned around and rolled away as a powerful beam almost hit him. He looked up to see the Destroyer and his eyes widened in horror!

"What are you doing here?" Thor asked with a snarl.

"Hello brother." Came Loki's voice from inside as Thor was horrified, "Or adopted brother."

"What?" Thor asked in disbelief.

"I am Laufey's son." Loki's voice said, horrifying Thor even more, "Odin picked me up when I was a baby to use me as a peace treaty. And now that I know, I will have my vengeance. Goodbye."

And with that, the Destroyer fired another beam as Thor flew away to avoid it. He threw Mjolnir at the Destroyer, staggering it back slightly before catching it and flying at the Enchanted Armor at full speed, smashing into it with Mjolnir and sending it down before it fired a powerful beam that sent him flying off.

Thor recovered himself as he avoided some strikes from it before smashing it twice with Mjolnir, though it wasn't that affected. He then fired some lightning as it fired a lightning beam of its own and both the beams exploded on colliding, sending them both flying back by a few feet.

Thor got up and charging another bolt, fired at the Destroyer as it fired a heat beam and there was another explosion, though they both maintained their footing this time.

Thor then twirled Mjolnir and three tornadoes came up as he flew into the sky. The Destroyer was lifted up too as it fired two beams which Thor deflected with Mjolnir before absorbing a third one inside. He then flew closer to it and there was an explosion.

A few seconds later, Thor landed on the ground as the Destroyer lay, battered by its own energy. He sighed in relief, thinking he had done it, when to his horror, the Enchanted Armor got back up.

It fired another heat beam at him and he was sent flying back. Getting back up, Thor fired some lightning but it used a magnetic field to block it, rendering Thor's attack useless.

Roaring with rage, Thor threw Mjolnir at it and it fell down before twirling it and flying off while holding to the unbreakable thong. The Destroyer took off after him, matching him in speed.

"HEIMDALL!" Thor yelled, "OPEN THE BIFROST!"

There was no response as Thor continued calling out to Heimdall while the Destroyer gained on him and was about to fire another beam.


Asgard

Heimdall had been trapped in ice by Loki but he could hear Thor's voice. Using all of his willpower, Heimdall broke free of the ice and grabbing his sword, swiftly dispatched the two Frost Giants guarding him.

He then put the sword inside as the Bifrost started opening up.


Just before the Destroyer could fire, both it and Thor were sucked in by the Bifrost.


Asgard

Heimdall fell back as Thor got up and so did the Destroyer.

"There is only one way now." Thor said as he held Mjolnir with both hands, "Allfathers give me strength."

And with that, a powerful beam shot out of Mjolnir. It was the God Blast. It hit the Destroyer with all of Thor's godly energies as Thor gave a mighty roar. The Enchanted Armor was sent flying back as the powerful God Blast started heating it up and in a minute, there was a mighty explosion as Thor and Heimdall were both sent flying back by many feet.

When the dust cleared, the Destroyer no longer stood there. There were only pieces lying around.

Thor immediately turned to his friend, "Heimdall! Heimdall!"

"Lo-ki…." Heimdall said hoarsely.

"I know." Thor said, "You need to get to the healing room."

"The….Jo-tuns." Heimdall said.

"I will take care of them." Thor assured as he flew Heimdall and dropped him near the healing room. Heimdall nodded in appreciation and walked inside. This place untouched for now in the battle that was going on.

Thor could hear the fight going on in the middle of Asgard. The battle between the Asgardians and the Jotuns.


In the middle of the city, the battle was going on in full force. With Odin in his Odinsleep and Frigga never leaving his side, the invasion had been easy for the Jotuns as they had destroyed a lot of buildings and killed a lot of civilians and soldiers before Sif and Thor's recently returned brother Balder had rallied the remaining soldiers for a last stand.

They were all standing inside a fortress, weapons at the ready as three very huge Frost Giants were trying to batter the gate.

These three were the largest Frost Giants in the history of Jotunheim, half as tall as the fortress itself. Laufey was watching with a smirk as they continued battering the gate.

With one hit, they managed to shatter the upper part of the door.

"You are soldiers of Asgard!" Sif said from horseback to the unnerved soldiers, "No matter what comes through that gate, you will stand your ground."

With another hit, they pushed the doors open and the three huge ones entered as Sif's eyes widened in horror. They smashed their huge weapons on the ground, killing many soldiers as one of them sent a few flying off with a swing of his weapon.

Laufey and the other Giants charged inside as Balder ordered, "VOLLEY!"

The archers fired their volley of arrows as many of the Jotuns were hit and sent staggering back and some even died. Sif rode on her horse and sliced one Giant deeply in the abdomen with her double edged sword, killing him as Balder leapt at another with his two swords and stabbed through the mouth, killing him.

The huge ones were causing a lot of damage though as one of them kicked Sif hard and sent her flying back. She fell down and lost consciousness.

"SIF!" Balder yelled in horror before jumping away to avoid an icy protrusion. He turned to see Laufey smirking at him in challenge. He dodged another icy protrusion with a flip and charged at Laufey with a roar who summoned two swords of his own.

One of the three huge Giants was about to kill Sif with his axe when suddenly a flying figure hit the back of the axe, breaking half of the head as the Giant looked at it horror.

They looked up to see Thor hovering in the air, an angry look on his face.

"PRINCE THOR IS HERE!" One of the soldiers yelled happily as all of them cheered. The arrival of Thor had given them renewed vigor.

"BROTHER LET'S FINISH THEM TOGETHER!" Balder said happily as he continued dueling Laufey while Thor nodded.

"Thunderer!" One of the three huge Giants said, "Now you will die."

"HAVE AT THEE!" Thor roared as he flew at him and he brought out a huge club of his own, clashing it with Thor's Mjolnir twice as the impact formed a crater in the ground.

Two ravens witnessed the battle and flew into Odin's bedchambers where he lay with Frigga next to him. One of them perched itself on her shoulder while the other one perched itself near Odin and both of them shrilled alarmingly. Odin's snapped open as Frigga looked overjoyed.

"My king!" She said happily as the two joined their heads.

"My queen!" He said with equal happiness, "Finally. My son has returned."

Frigga looked shocked and overjoyed at the same time.


The Giant hit Thor hard with the baton, sending him crashing into the ground and forming a crater. The third one tried to hit him with his sword but Thor grabbed it with both hands and flipped the Giant to the other side, crashing him into an empty building.

That was when the one with the club collapsed a column on top of him. The three watched as Thor emerged once again and raising Mjolnir declared, "Thor will not fall by your hands, monster!"

Lightning cracked in the sky and Mjolnir before Laufey sliced Balder across the shoulder and kicked him on the knee, sending him to the ground before punching him out temporarily.

"I think not." Laufey said as huge ice shards came out of the ground and trapped Thor inside them. That was when he was stabbed in the gut and looked down to see Balder glaring at him. He retracted the sword as Laufey fell to his knees in pain and Balder cut off his head.

Thor grunted and shattered the shard into pieces with his hands before one of the huge Giants grabbed him and threw him into a building.

Using the God Blast had weakened Thor which is why he was having such a hard time with the three huge Giants. He fell down as Mjolnir fell out of his grasp.

The one whose axe he had broken was now carrying a mace in its place. The three then brought down their weapons on him simultaneously- mace, club and sword as Thor grunted in pain before the one with the club grabbed him and brought him closer to his mouth, intending to devour him.

Thor raised his hand and Mjolnir flew towards him. Catching it at the last second, he hit the Frost Giant hard on its teeth, shattering them as he screamed in pain and let Thor go. Thor flew into the air and declared, "I have felt your wrath Frost Giants! Now you shall feel mine!"

He charged Mjolnir with lightning as the sky darkened and a powerful lightning blast descended from above, enhanced by Mjolnir as Thor roared, "FOR ODIN! FOR ASGARD!"

The three huge Giants were vaporized by the powerful lightning blast as Thor felt his entire body burning with power and lightning. There was zilch left of the three now.

With their king and the three strongest Frost Giants dead, the remaining Jotuns' resolve broke as Balder, Sif and the remaining soldiers started overpowering them.

That was when a dark beam of energy hit Thor and sent him flying back by many feet. He crashed into another building. He looked up to see Loki in the air, wielding dark energy in his palms.

"Welcome home, brother." Loki smirked.

Thor got up with a snarl as Loki said, "You had this coming."

He fired another dark beam of energy and before Thor could block it with Mjolnir, it hit him and sent him flying off, destroying more buildings.

As he tried to get up, Loki landed in front of him and brandished Gungnir which he taken for himself after Odin fell into the Odinsleep, "You and Odin deserve what's coming."

"I do not wish to fight you Loki." Thor said brokenly, "We were raised together. We played together, we fought together. Do you remember none of that?"

"I remember a shadow. Living in the shade of your greatness." Loki snarled, "You choose to remain blind to Odin's lies."

With that, he kicked Thor on the chin, sending him to the ground. He tried to bring the spear down on Thor but he rolled away to avoid, "YOU CAN'T BETRAY YOUR OWN PEOPLE!"

"THEY ARE NOT MY PEOPLE!" Loki roared back as Mjolnir returned to Thor. Mjolnir and Gungnir then clashed before Thor hit Loki hard, sending him flying off and crashing into a building. Twirling Mjolnir, he flew towards the building while holding onto the thong.

Loki got back up and fired a powerful beam of dark magic at Thor who used Mjolnir to block and moved further towards Loki, hitting him and sending him back.

He then flew into the air and raising Mjolnir, summoned a powerful lightning bolt and discharged it at Loki, who dissipated into moths that flew off, avoiding the lightning.

"You cannot beat me brother. You never could." Thor said as the moths assembled behind him and reformed Loki, who enhanced the strength in his hands with dark magic and hit Thor's shoulders, sending him to his knees.

"Things change." Loki snarled as he grabbed Thor's shoulders and started burning into them with dark magic. The God of Thunder screamed in pain before grabbing Loki and kicking him away.

"Surrender brother." Thor said as he raised Mjolnir.

"No." Loki said as he fired three blasts of dark magic which Thor deflected with Mjolnir and lifted Loki up by the throat.

"Come brother. You have much to answer for." Thor said in a voice that was a mix of rage and pain.

"I won't." Loki said, "You thought I would risk this battle in a duel with you?"

"What did you do?!" Thor exploded as various scenarios ran in his mind, "WHAT DID YOU DO?!"

Loki smirked, "I placed Surtur's crown on the Eternal Flame."

Thor's eyes widened in horror as with a roar, he threw Loki to the ground hard, knocking him out.

A 1000 feet giant fire monster rose as Thor watched in horror.

"Tremble before me Asgard! I am your doom!" Surtur roared as he started destroying the buildings with his Twilight Sword.

"SURTUR!" Thor roared, attracting the legendary demon's attention.

"Thor!" Surtur said, "I will destroy Asgard."

Many smaller fire demons manifested from Surtur's flames, attacking Asgard as Thor flew into the air and hit some of them with a lightning bolt, sending them flying back. He landed in their middle with a roar and sent two of them flying off with a hit from Mjolnir before sending the others flying off too.

Surtur fired a powerful flame at Thor from his Twilight Sword which he blocked by twirling Mjolnir. Surtur then raised his hands and the flames emanating from him formed more fire demons which jumped down at Thor from above.

Thor threw Mjolnir at some of them, killing them as it returned to him and he flew into the air twirling it, killing more of them.

"Tear him apart and bring me the hammer." Surtur commanded.

Down below Sif, Balder and the remaining soldiers were slicing at the fire demons with their swords, killing them though more popped up in their place.

Thor was surrounded by many fire demons before he used his lightning to kill them all. Surtur then hit him with a fiery blast, sending him flying back as Mjolnir fell out of his hands.

"I am Asgard's doom." Surtur declared, "What were you the God of again?"

Thor started getting up and to his horror saw Fandrall, Volstagg and Hogun lying on the ground, dead. They had been killed by Frost Giants.

That, combined with Surtur's taunts, made Thor roar in a rage he had never felt before as his body suddenly started emanating lightning and a huge lightning bolt hit the ground. It killed most of the demons as Surtur was sent flying back by a few feet.

Thor looked at himself and saw the lightning emanating from his body. He then saw hordes of fire demons approaching and leapt into the air, jumping in their center as his lightning threw them all away.

As more charged at him, he flew at them in a rotatory motion and killed more. He punched many more of them away as lightning bolts emanated from his body and descended from the sky to kill more of the fire demons.

He then kicked another away as his lightning destroyed more before blocking another one's punch and hitting it and many behind it, killing them all.

Sif sliced one down before deflecting another's attack and slicing it down too.

Balder rolled away to avoid one's attack before throwing his sword at it, killing it and then sliced another down before picking up his other sword.

Thor hit another one with lightning, sending it flying off before grabbing another and flying up with it and then slamming it to the ground as lightning bolts killed more of the demons.

He then snatched swords from two of them and in a rotatory motion, sliced more of them down while his lightning killed more of the demons as Surtur watched.

Thor then summoned Mjolnir to him and with a roar, fired a God Blast at Surtur, sending him flying back by many feet as he was greatly weakened while Thor ran out of energy and fell on the ground, panting.

Surtur got back up with a roar, "I will destroy Asgard."

Gungnir, which had been lying on the ground all this time suddenly hovered in the air and flew into the hand of Odin.

Thor looked at him, "Father?"

"Thor. You are worthy of your titles, your power, your loved ones, your hammer." Odin said, "But you are not Thor, the God of Hammers. You are the God of Thunder. The hammer was merely to focus your powers but they lie within you."

"We will finish Surtur together." Thor said.

"No son." Odin said, "I may not have been a good father but let me correct it now. I just wanted to tell you, your mother is Gaea."

"The Elder Goddess?" Thor asked in shock.

"Yes son. I asked her to give me a son more powerful than all of Asgard who would be powerful on Earth too." Odin said, "Like Loki, you deserved to know. But now let me right my wrongs."

With a roar, Odin charged towards Surtur as Gungnir clashed with the Twilight Sword, sending energy around.

Surtur charged the Twilight Sword with all of his energy as Odin charged Gungnir with all of his.

"This is your end, Allfather." Surtur snarled.

"For Asgard!" Odin said.

"FATHER! NOOOOOOOOO!" Thor said in horror as the brightly glowing weapons clashed again and there was an explosion of light.

When the smoke and brightness cleared, both of them were nowhere to be found.

"Father?" Thor called out in despair, "Father?"

He got no response. He fell to his knees in despair as Sif and Balder held him for comfort.


Donald wiped a few tears from his eyes as Kara unconsciously grasped his hand to provide comfort and Donald squeezed it back.

The two looked at each other for a few seconds before realizing where their hands were and moved them away, recovering themselves.

"I am so sorry." Kara said, her greatest sympathies going out to the God, "I know what it feels like."

"I know you do." Donald said sadly, "Now you understand why you need to put Astra down at all costs?"

Donald's tale had been an eye opener for Kara. She thought not killing made her better than everyone. It didn't. It made her weaker and unwilling to do what's necessary. No more.

She gave a firm nod, "I do."

"Good." Donald said.

"Still, I don't want to ask, but what did you do then?" Kara asked Donald.

"There was a funeral." Donald said sadly, reliving the pain as Kara immediately regretted her question but Donald saw her expression and shook his head, telling her not to blame herself, "We had won but our dead were beyond the count of grief. Many had lost their lives including my father and my friends Fandrall, Volstagg and Hogun. Never again will the Nine Realms witness the Warriors Three again."

Kara looked at him sadly as she remembered her own parents and friends from Krypton she would never see again.

"After the funerals, I just thought nothing was left for me at Asgard." Donald said, "And while Gaea was my birth mother, Frigga still remained my mother for me. She comforted me and I comforted her as she grieved for father and what Loki had become. He was banished to the Isle of Silence by the two of us where he now resides, contemplating his crimes. And I left Mjolnir in the care of my brother Balder before coming back here due to my connection to Earth. Since then, I have been Donald Blake."

Kara nodded as Donald got up and took out a beer for himself and drank it.

"You're not alone any longer." Kara told him, "You have me."

Donald nodded at her in appreciation with a smile, "I know Kara. I know."


And that ends my version of the Thor Origins Trilogy. This chapter was my own favorite to write so far. I think it is proven now that Thor has been holding back massively this entire story except in his fight with Superman who is a combo of the Arrowverse and Smallville versions with powers of the Smallville version.

I loved giving a reference to The Lord of the Rings: The Return of the King with Sif and Balder rallying the Asgardians.

I was pretty disappointed by the Destroyer in the MCU as all it did was fire a beam when in the comics it can crack Uru metal too and can manipulate the magnetic field and also fire electricity, anti-matter and plasma beams.

The fights with the Frost Giants and Loki were taken from The Avengers: Earth's Mightiest Heroes which is one of the best superhero animations I have ever seen and is on par with Justice League and Justice League Unlimited.

And while Thor isn't my most favorite superhero (though he is in the Top 3), he is my most favorite OP superhero and I was pretty frustrated by how much the MCU nerfed him before showing his true power in Thor: Ragnarok and Avengers: Infinity War.

And Balder is played by Chris' older brother Luke Hemsworth on Chaos Sorcerer's suggestion so thank you to him.

Hope you all enjoyed and are looking forward to the next chapter.
