Thank you to everyone who has favorited, followed or reviewed this fic so far.

Some people expressed concern in the last chapter that Magni beating Thanos would be a disappointment after all the build-up to Odinson vs. Thanos, but here's the thing, he won't. Magni's role is gonna be like Steve's in the final fight of Endgame, in that he will put up a good fight and look like he can do it, but he won't be enough alone.

Guest: Thanks for the review and title suggestion, though I have another one in mind, but thanks still.

Chapter 13- A Legendary Battle

Magni twirled Mjolnir and the two charged each other. Magni leapt up and swung Mjolnir upwards, hitting Thanos under the chin and knocking him down into rubble.

As Thanos got up, Magni threw Mjolnir but Thanos ducked to avoid, only for it to unleash a thunderclap behind him which managed to hit him, knocking Thanos to his knee.

Magni caught Mjolnir on return and leaping up, kneed Thanos back before hitting his knee with Mjolnir and following up by a powerful punch to the face, before striking his face with Mjolnir twice, the second strike breaking the helmet as Thanos staggered back.

Magni then threw Mjolnir at Thanos, staggering him back and then calling it back, threw it at him again, staggering him back once more and then, fired a powerful lightning bolt from Mjolnir which ripped the ground and hit Thanos, throwing him down.

Magni raised Mjolnir skyward and as clouds gathered, an even larger lightning bolt was summoned which struck Thanos, making him roar in pain. Magni leapt at him with Mjolnir raised but he rolled away at the last moment and picking Magni up by the throat, slammed him to the ground.

Magni rolled away and got up as Thanos picked up his sword and threw his broken helmet away. He swung but Magni blocked or dodged a few times before being stabbed in the leg. He yelled in pain but tried to strike with Mjolnir. However, Thanos grabbed Magni's wrist and stopped the strike, dropping his sword and punching Magni with his other hand, knocking Mjolnir away.

Magni was kicked away but got up as Thanos kicked his sword into his hand.

Odinson, while proud of his son, wasn't going to just sit back and watch the fight.

Gritting his teeth, he grasped the sword of Thanos, and slowly pulled it out as blood poured out of his wound like a fountain, but he persisted till the edge of the blade was out of his body.

Then getting up, he twirled it and planted it on the ground before twirling Stormbreaker as lightning flashed from him.

Thanos watched as Odinson sped between him and Magni. "You fought well son, but this is my fight."

"It is time to end your pitiful life now", Thanos said as he fired a powerful cosmic blast but Odinson deflected it with Stormbreaker to the top of an empty building, shattering it.

Odinson picked up Thanos' sword and challenged. "Fight like a true warrior, Thanos."

He then tossed Thanos his sword as he roared madly, shaking the ground, and then using his cosmic energy, flew up into Space, with Odinson flying after him.

"Those eyes, deep in them, I see the same light as your father's eyes", Thanos said before gloating. "And I shall enjoy extinguishing them."

"Why did you take my son?" Odinson snarled.

"So I could make him tell him the truth about you, and make him my son instead", Thanos said, angering Odinson. "I will make a better fa-"

"SILENCE!"

Lightning cracked in Space itself while a storm was created as Thanos flew higher and Odinson flew after him, his entire body covered by an aura of lightning.

Odinson flew towards Thanos, firing lightning as Thanos defended himself with a cosmic force field, gritting his teeth due to the pressure from the angry God of Thunder.

He then raised his hand, summoning cosmic energy down on Odinson to hit him, who barely avoided, flying next to it as he rushed Thanos, only for him to hurt giant fireballs at Odinson.

Odinson deflected two and was hit by a third, making him stagger back before he took the full force of another one, this time not flinching, and like that, he flew through all fireballs, taking their full force without any issue.

Just before he could ram into Thanos, the Mad Titan hurled an asteroid at him with his full strength, throwing him back as Thanos threw another.

This time, Odinson sliced it with Stormbreaker and flew at Thanos again, who hurled more asteroids but Odinson dodged all of them before finally hitting Thanos with powerful lightning, making him fly back as he roared.

Then Thanos raised his hands as orbs circled him, and suddenly merging, fired a powerful cosmic beam at Odinson, making him fly back by a few feet.

As he recovered, Thanos formed those orbs again but this time a powerful lightning strike from Odinson destroyed them all.

Odinson summoned more lightning as it struck down on Thanos to hit him but he barely avoided every time before forming countless red needles of energy which he hurled at Odinson.

He managed to deflect some but many more hit him, making him grunt in pain and drawing blood before he roared, hitting himself with lightning as he was healed.

As Thanos summoned his orbs again, Odinson screamed and at amazing speed, flew between the orbs, right into the Mad Titan, hitting him at full force as he spat out blood and was sent reeling back by many feet again.

"You are the first to draw blood", Thanos grunted.

"I shall draw all of it", Odinson said.

Thor side-stepped to avoid a beam from the Destroyer, hitting some Sakaarans who got killed instead before Bill rammed into it, sending it back while Clark lifted it up and punched it into Kara who interlocked her fists and hit its head, sending it to J'onn.

It tried to fire at him but he turned intangible while Thor hit it with Mjolnir, sending it flying off again.

The bigger battle was in full force.

Oliver, Ollie and Adrian were out of arrows by now and were smacking whatever enemy came within reach with their bows, having cuts and bruises all over them.

Laurel and Dinah were bleeding, with sore throats, but they were going to keep fighting as well.

A Fire Demon breathed fire on a Chitauri, Dwarves worked in coordination to take down a Chitauri Gorilla, Light and Dark Elves took down various enemies in elegant coordination, while many fell themselves, and Frost Giants stepped on and froze whatever came at them and wrestled with some Chitauri Gorillas that tried to battle them.

Ray was lying on the ground by now, his suit broken in various places, preventing him from taking flight.

As the Destroyer made to fire again, Thor and Bill fired God Blasts together while Magni and Storm fired lightning and Clark and Kara fired Heat Vision as Fate fired a powerful blast as well.

The Destroyer still hadn't fully recovered from its previous fight, so this time, it could not take all of the attacks together.

There was a huge explosion, sending everyone back, and when it cleared, bits and pieces of the Destroyer were lying on the ground. It has finally been destroyed.

Thanos spun and got onto Odinson's side, smacking him to away as he grunted before Thanos summoned multiple orbs again, and this time all of them flew at Odinson.

He managed to avoid but they followed him, trying to hit as Odinson flew to escape them with all his speed, only for Thanos to hurl multiple fireballs at him.

Odinson maneuvered in the air, expertly dodging the fireballs as the orbs still chased him, only for Thanos to summon a blast of cosmic energy that hit Odinson, making him stagger back.

Turning to the orbs, he blew out powerful air from his mouth and they were all sent flying off before he once more rammed into Thanos at full speed, making him fly back once more as he spit out more blood.

Thanos roared. "INSOLENT FOOL!"

And then he fired his needle of red energy at Odinson, who managed to avoid two of them but five more impaled him, before Thanos summoned multiple fireballs and a blast of cosmic energy simultaneously.

They all hit Odinson, sending him crashing from Space back to Earth, on the outskirts of Central City as several more fireballs crashed on him but he rolled to avoid each one of them.

He then staggered up and looked to see Thanos lowering himself to the ground. The Mad Titan landed on the ground, making it shake as the two glared at each other.

The two clashed their weapons, sending out a powerful shockwave that shattered cliffs and made the water rise before Thanos stabbed Odinson in the shoulder.

Odinson growled and slowly pulled the blade out before slamming Stormbreaker on Thanos' chest, drawing blood as he growled this time before pushing Odinson away, and his weapon with him.

Odinson slid down to avoid another strike from Thanos and leaping up, kicked him back before trying to strike him again but Thanos blocked with his sword and punched him back.

As Odinson got up, Thanos summoned 4 orbs, all of which rushed at Odinson, and he leapt to avoid before slicing one with Stormbreaker, and then spinning, kicked another away before bringing Stormbreaker down on a third, destroying it.

As the other two neared him again, he gave them both a fast slice in a spin motion, destroying them both before Thanos sent him back with a blast.

As Thanos made to strike him again, he rolled away and got behind Thanos. Just as he turned around, Odinson gave him two slices on the chest in a spin motion before flipping and kicking his chin, sending him back once more.

Thanos roared as this time, countless white needles flew from all around and Odinson had to roll away to avoid each and every one of them.

Thanos then raised his hand as his cosmic energy formed a dragon like being, which fired a powerful ball of energy at Odinson, sending him flying off.

As Odinson staggered up, it fired again but this time he deflected with Stormbreaker before rushing it and slicing it down effortlessly.

He was then hit by a piece of ground thrown by Thanos, which sent him flying back as Thanos summoned two orbs which spun around, firing more of those white needles.

Odinson formed a force field that protected him from them all before Thanos punched the ground, empowered by cosmic energy.

The cosmic energy then erupted from the ground underneath Odinson, giving him an uppercut that sent him flying high into the air before crashing to the ground, forming a crater.

As he staggered up, Thanos formed two of those orbs again as they spun and fired white needles while red needles rained down from the sky.

Odinson formed a force field, gritting his teeth as the needles all crashed against it, inching it inwards but he stood up to all of it before expanding it outwards, hitting the orbs and destroying them both before hitting Thanos as well, sending him flying back.

As he staggered up, Odinson hurled Stormbreaker on him and it hit him on the heart as Odinson rushed up to him and pushed it further in as Thanos growled.

"You..", he snarled as he looked back up at Odinson. "You should have…you should have gone for the head."

And with that, he head-butted Odinson, dazing him before punching him away, and then ripped out Stormbreaker, putting it on the ground, before Odinson summoned it back to himself.

Thanos then flew off back to Central City as Odinson flew after him, slicing down a Leviathan in the way before raining lightning down on some Chitauri and Outriders as he saw the Jotuns smacking them all away while the Elves all fought in coordination with clean movements, slicing down their enemies even though quite a few of them were sliced down as well.

Thanos landed on the ground, shaking it as he roared. "This is where all of you shall die!"

Odinson landed in front of him, shaking the ground again and pointing Stormbreaker at him said. "We may die, but one this is for certain. This shall be your burial ground as well."

Thanos slammed the ground with his foot, shaking it as many were thrown off their feet as the two clashed their weapons again, a shockwave destroying buildings and killing more.

Odinson ducked to avoid another swing before trying to strike but this time Thanos blocked before blowing him back by cosmic energy, only for Clark to ram into him and send him back.

He swung at Clark who backed to avoid and punched him off again. As he flew back at him, a blast of cosmic energy from Thanos sent Clark flying back as well before he fired a green beam all over from his mouth, killing many of the forces from Universe-X Odinson had brought and also sending him, Thor, Bill, Clark, Kara and Fate flying back.

Odinson staggered up as Thanos fired the same beam at him again, sending him flying back before he flew up into the air, summoning powerful lightning and storms.

And then he fired down powerful lightning on Thanos consistently, not giving him any opening to fight back as Thanos roared in rage and pain as a cosmic energy blast emanated from him, and eventually both of them were sent flying back.

"WHAT'S THE MATTER?" Thanos roared. "ARE YOUR POWERS WEAK IN FRONT OF ME?"

As Odinson staggered back up once more, Storm called out to him. "Odinson!"

He turned to her, Thor, Bill and Magni as she said. "Use our power."

"And kill the bastard", Thor said as all of them fired lightning together at Odinson, giving him a temporary boost as he took all the power in, adding them to his own.

Thanos charged but Fate held him back with a force field, which Thanos tried to shatter with his cosmic energy empowered fists as Odinson took in all the power.

"This power….." Odinson said.

Thanos managed to shatter Fate's barrier, sending him back and charged Odinson, whose eyes glowed as he suddenly fired a powerful God Blast as well as lightning all together, hitting Thanos as he roared in pain at the power boring through him and burning him, throwing him back.

"You're gonna die of course", Adrian smirked sarcastically as he gave a mock bow. "But if you do somehow come back from the dead, give your regards to my son, will ya?"

Thanos was thrown to the ground by the powerful attacks as it shattered while he staggered up, his entire body burnt and bleeding.

"Even if you defeat me", Thanos snarled. "I have a bomb on my ruined planet back in our Universe, and it shall destroy the Multiverse."

Odinson roared as he leapt at Thanos and with a mighty swing, chopped off his head, sending it to the ground.

One second later, the body fell down as well, shaking the ground.

"He said something about a bomb to destroy the Multiverse", a staggering Barry said before falling down and losing consciousness due to exhaustion.

Fate immediately opened a portal as Odinson, Thor, Bill and Magni flew through it right into the ruins of Titan in Universe-X, where there was a powerful bomb indeed.

"Come on, let us stop it together!" Thor said as they combined the might of their weapons, forming a powerful force field with the Mjolnirs and Stormbreakers as all four of them gritted their teeth, trying to hold it back before there was a powerful explosion that sent all of them flying off, but that was the best it did.

"It looks like we have done it", Bill panted.

"Yeah", Odinson said as all of them flew back through the portal back to Earth-1.

"I do not think this was the end", Fate said as he looked to the ruins of Sanctuary II. "I feel there is more there. Enough to destroy this Universe at least."

Before anyone else could react, Odinson flew at it at full speed, reaching the ruins just as the bomb went off but Odinson roared as he absorbed the energy into himself, his roar echoing throughout the city as the fires were seen, but they did not spread, as Odinson absorbed all of them, staggering to the ground and dropping Stomrbreaker as he finally felt the exhaustion from the fight.

A minute later

The others all watched as Odinson staggered out of the wreckage, looking very exhausted, but still alive.

"No….no one God could have survived that!" Thanos' head spoke in horror.

"I am not just one God", Odinson said casually before lifting Stormbreaker and with a roar, sliced Thanos' head into two before swiftly slicing it all into several small bits, and then destroyed them with powerful lightning, finally ending him.

He then looked at everyone else who had assembled, the heroes as well as the ones from Universe-X and raising Stormbreaker announced. "THANOS IS DEAD! NOW ONLY HIS FORCES STILL ON UNIVERSE-X REMAIN! BUT WITHOUT THE HEAD, THE BODY CANNOT SURVIVE! TAKE UP ARMS! FIGHT! FIGHR FOR YOUR FREEEDOM AND DESTROY WHAT IS LEFT!"

All cheered loudly once more as Odinson got down on one knee, holding Stormbreaker and planting it on the ground as for the first time in years, he felt at peace, and his self-hatred lessened.

They had won.

Well, hope this chapter was enjoyed, including the battle with Thanos which I hope was legendary enough.

As for Thanos flying, he has shown the ability of unaided flight in some more recent comics, so I decided to have him use it here too.

Next chapter will end the main plot and the one after that will be an epilogue to this series, so hope all enjoy it.
