A Not So Evil God In Fate/Grand Order

~Seth's Original World~

It happened thousands of years ago when the world didn't have any civilization aside from that of the Gods. A threat capable of destroying and consuming the life those same Gods had just barely created reached Earth.

An alien star from far away, whose only purpose was terminating the life of whatever planet with civilization it managed to encounter.

That star sent three beings to the planet in the hope of destroying every being in it. However, before those three got past the clouds, they were intercepted.

Sea of Japan

"Err... These fellas are comin' here like they own the place. I ain't got time to deal with this." A black-haired man with a toothed katana said while taking wax out of his ear. He had a blue shirt that only covered part of his torso, white pants, and a bamboo hat.

"Shut up. I didn't want to be here either. Now, will you scram from atop of my head, or do I have to eat you alive?" An enormous, green dragon with two horns and two whiskers asked the little man, with an incredibly deep voice.

"Ya trynna be funny, Snake Head? 'Cause I wanna have some new katana right now." The man's voice was lazy, but at the same time, threatening. The sky turned dark as thunder rumbled across the area.

"Heh. Why don't you try it, you caveman? I'm sure your Gods will pay handsomely to get your head back from my stomach." The sea below went wild with his words, like it had become alive.

In front of them, a giant and mysterious figure observed these two beings bicker among themselves. However, that didn't last long as the titanic creature opened its mouth before firing a white beam at the two.

Contrary to what one may expect, the Dragon and the man were alert the whole time. The katana-wielder simply waved his weapon and dispersed the attack.

"Ain't that rude? You gotta respect when others are talking. Doncha agree, AK?" He lazily looked at the Dragon below him.

"Hmph. For once, I agree with you, brat of the storms. Let's kill this trash here first, or we would be the laughing stock of the other Gods if we kill him last." The Dragon's itch to devour the figure in front of him was apparent for all to see.

Gulf of Mexico

A green serpent, hundreds of meters tall, was observing the figure of a girl that got dwarfed by his size. It had feathered, multicolored wings and a mane made out of red and green leaves. Rocky protrusions extended throughout his whole body as if it was an exoskeleton.

Different from the last place, this creature was the only one here.

"Why do you seek the destruction of this planet?" The giant serpent asked after a long staring contest. His voice sounded like a whisper.

"..." No response.

"You have no chance of winning. Please reconsider it, youngling." He tried to reason with her so they could avoid having to fight.

"..." Again, no response.

"Return from where you came. There is no need to hurt a land that is prospering." He gave her a last warning, hoping this time she could reconsider her intentions.

This time, he got a response. However, that response was a blast to his face. Smoke covered the upper part of his body, which dispersed over time, revealing the unharmed serpent.

"Very well. My kindness has a limit, and you just overcame it." His voice was not calm anymore. Now, it reflected his fury, and the world trembled with it.

Ionian Sea

"Wahahaha! Isn't it great? We can fight again! How long has it been since I've last seen battle-sweat?!" A man with a horned helmet laughed loudly. He had ginger hair and beard, wore a red cape that fluttered with the wind. He didn't have anything to cover his upper body, showing well-defined muscles with black tattoo-like markings. He had a metal belt and tassets over green pants, from it, descended the famous 'crotch-flap.' Two golden and black gauntlets, one on each side. In his right hand, he was holding a small hammer surrounded by lightning.

"There is no need to be that excited. Save your enthusiasm for when we have to destroy that thing that is hovering above the planet." Seth, in his animal form, rolled his eyes at the man.

"What are you saying, old friend? We've known each other for so long. I know you are also thrilled to fight!" The man didn't feel discouraged by his words. By the looks of it, nothing could ruin his fun today.

The Egyptian God simply smiled at being found out. "Heh. I just hope it doesn't end in a second. Otherwise, me coming here would be meaningless."

"Wahaha, don't be like that! You can come with me to Valhalla and drink until we pass out or fight until we both collapse like we always do!" The Viking-looking God offered Seth, but just then, another Deity joined the battlefield.

"You uncivilized muscle-heads, when are you going to take this seriously?" A storm cloud approached their location, and with it, an incredible pressure began to engulf the area.

"Stop opening your teeth house and come here, old God." The hammer-wielder furrowed his brows, his mood not as happy as before.

"I need not show my form in front of you two, nor this alien threat." A response filled with disdain was all that he got.

"Where is your mind's worth? You are a shame as a ring-giver." To him, someone who hid from a battle was nothing more than a coward and didn't deserve the title of King.

"Don't be so surprised, Thor. I bet he is just here to run away from his wife's wrath. Isn't that right, Zeus? How much time did you stay loyal to Hera? One day? That's a new record for you! Hahaha!" Seth didn't have any trouble mocking the old God, even going as far as laughing at him, something Thor did too.

"Hey, old man. Do you want to meet some victory-maiden? I already introduced some to Seth, but I don't know if they are into people with back problems. Wahaha!" Both Gods fist-bumped while continuing to mock Zeus.

"SILENCE!" Multiple bolts of lightning fell from the sky, and the world quivered at his power. However, Thor and Seth just laughed while holding their stomachs, not caring about him at all.

That was until the last of the three beings sent by the star appeared in front of them. As if someone had flipped a switch, the three stopped their 'banter.'

"Let's do this!" With Thor's exhilarated shout, the battle began.

Three days, that was the duration of the fight. A number that means nothing compared to their lifespan. The result? An overwhelming victory for the Gods.

In the Sea of Japan, the Male Titan was cut in half and then devoured by the Dragon. In the Gulf of Mexico, the Female Titan was torn to shreds by the giant serpent's strong winds. In the Ionian Sea, the final Titan was scorched to death by fire and lightning.

"You dragged this unnecessarily. I should have helped the others instead of you." Leaving behind those words, Zeus returned to Olympus still without showing himself. He hoped Hera had calmed down by now.

"Big talk for someone who did nothing." Seth shook his head in disp.l.e.a.s.u.r.e. The only comfort he had was that Hera was going to kick his a.s.s for sure.

"Did you find something?" Thor was already used to Zeus' personality, so he paid it no mind. He wanted to know if they at least got something out of this fight.

"I could get in her mind for a bit before she kicked me out. However, I only got her name and from where she comes. Supposedly, she is named Sefar and belongs to an alien star called Velber, the one that is above us." Seth told the Norse God what little he could find.

Thor grinned widely. "Are you up to wreak havoc inside that thing?"

"Why do you ask if you already know the answer." He gave him a battle-hungry smile as he turned to the sky, more concretely, space.

The two Gods then ascended even higher, quickly exiting Earth. What awaited them was a big eye surrounded by metallic, petal-like armor.

Without delay, they shot toward one part of its body, and when they did so, Velber finally noticed them. However, by that point, it was too late.

Thor and Seth rampaged inside the star for days. No matter how many times it activated its defensive mechanisms, it couldn't stop them.

When they eventually reached the core, its eye, the two used their most potent attacks, Asgard's Wrath and World's End, respectively.

The combination of their assault created an explosion that threw them like a rocket into space. After a long while, Thor and Seth crashed into different asteroids.

'We overdid it...' Was the thought in both of their minds when they exited the giant pieces of rock.

On Earth's atmosphere, a brown-skinned man with four arms and three eyes was watching the explosion that was nearing the planet and would engulf it if no one did anything to prevent it.

"Do you still not understand? Destruction is pointless if you gain nothing from it. I hope you find the correct answer soon, little brother." The man let out a regretful sigh before extending one of his hands forward. Like a black hole, it absorbed the whole explosion, returning tranquility to the world.

With nothing more to do, he returned to Earth, followed soon after by the other two.

Just like that, an alien threat capable of destroying the whole civilization of a planet perished at the hands of a minor group of Gods.

―――――――――――――――――――

"What are you doing here, Sefar?" Those memories from a battle that happened long ago made him ask this question.

The girl frowned slightly at the mention of that name. It was a name she haven't heard before, but for some reason, it wasn't unfamiliar with her.

"My name is not Sefar. I'm a warrior of the Hun, she who people call 'The Scourge of God,' nothing more." She emotionlessly replied while still locking eyes with him.

'No wonder Kingslayer is reacting to her. So she is Attila, I should get used to this genderbending nonsense sooner or later.' He thought as he examined her from head to toe.

"You even have Mars' real sword with you." The Thone of Heroes sure did wonders just with what people believed. He wondered what the extent of its power was.

"Marc—Mars' sword was something I obtained during my lifetime. There is nothing wrong with it." The first name Attila said made Seth's mouth twitch slightly. To think she would call him that, he could barely contain himself from praising her from coming up with that name.

The King of the Huns then looked around, taking in the scenario that was so familiar to her. "Is this...Rome?" She asked monotonously.

"You can say it is a copy of Rome. What you see is the result of what I caused not long ago." Seth unhesitantly admitted his 'crime' much to Saber's surprise.

"If you destroyed it...why was I summoned?" She was a tool meant to annihilate. What was the point of her being here if there was no civilization to obliterate?

"A Demon sacrificed his body and the rest of his energy to the Grail and called you here so that you could kill me." Now that he knew she was not Sefar, he spoke without much care in the world. Although the similarities slightly gave him mixed feelings.

"I see..." Her reply was short and concise, showing that she didn't care much about it. She then turned her attention to his spear. "Your weapon...it resembles my sword."

Attila was not referring to the shape, but the feeling they gave off, making her wonder which were the similarities between them.

"That's because it belonged to a certain God of War from a faraway land. Accompanying him in his demise, it lost most of its powers." He gently c.a.r.e.s.sed the shaft with its thumbs. Truly something—no, someone who stayed with him until the very end.

"Who was him?" The fondness she had for Mars when she was born made her interested in this topic, even if her voice lacked emotion or some grade of interest, for the matter.

"None other than me." There was no harm in her knowing, so he didn't have any problems telling her.

Saber furrowed her brows slightly, confused by his reply. "Your Divinity is...low. You don't seem to be a God." Her words didn't seek to mock him, but to state a fact.

When Seth opened his mouth to speak, he noticed Ruler's death. Like some sort of film, the last memories Jeanne experienced began playing in his mind.

'To think you went as far as to do that. It seems I underestimated you, Ruler.' While her death didn't sadden him in the slightest, it earned a little of his respect.

"Before that, are you willing to fight me, Saber?" He wouldn't get serious if she didn't want to fight, after all.

"Why?" They were just talking. She didn't understand the sudden question.

"Remember when I told you this was a copy of Rome? The real one is out there, ready for you to destroy." Now, THIS caught Attila's attention.

Her expression became cold and unfeeling. "Where is it?" Her emotionless tone had an icy edge to it.

"Defeat me, and I will tell you." Those words seemed to be the trigger. Immediately, Saber moved her sword, aiming for his neck.

He blocked her weapon with his spear, his lips curving into a faint smile. "That's more like it."

'I hope your prediction is not wrong, Stargazer.' He had used a grand part of his Mana to summon that Skeleton, although he still had more to spare, against her, he wondered if it would be enough.

One by one, he activated every ability at his disposal. Lastly, he stopped repressing his Divinity. With his eyes turning golden in color, the world was engulfed in a chaotic darkness like it was the end of times.

This battle would be the most difficult one he has ever had up until now. However, far from being nervous, he was looking forward to it, for old time's sake.

(A/N: Thor uses Kennings btw. In case you don't understand)
