Summary
In a universe where every person awakens a Planet as the foundation of their power, the strength of one's civilization determines their might. From martial worlds where warriors reign, to mystic realms teeming with magic, to ethereal domains of immortal cultivators, every awakened Planet becomes a reflection of its creator's path.
But Alexander Sebastian is different. Reborn with memories from a modern, Earth-like world, he forges something never seen before: a Technological Civilization. While others summon Qi, Mana, or Spiritual Power, Sebastian builds factories, launches satellites, and commands fleets of starships.
With logic as his weapon and science as his foundation, Sebastian begins to shake the very foundations of this Supernatural cosmos. When a Star Destroyer punches through planets and dimensional weapons turn worlds into nothing more than paper, even the proudest civilizations must bow before the cold, unrelenting force of progress.
Witness a tale where science defies fantasy, and technology becomes the ultimate path to dominance.

Summary
Yan Qing has survived first contact, alien politics, and falling in love with the most dangerous man on the planet. Settling down should be the easy part.
No, far from it.
Life in the Teleopean palace is full of quiet misreadings, cultural collisions, and the kind of danger that arrives dressed as diplomacy. When the Mys civilization appears at Amoro’s doorstep, their interest in Teleopea quickly turns personal. Their society runs on hierarchy and slavery. Their prince does not understand the word boundary.
As Yan Qing’s connection to the Ultimate Weapon deepens and an unknown voice begins reaching into his mind, peace slips further out of reach.
Falling in love was only the beginning.
Staying alive together is the harder part.

Summary
After World War I, over 70 German ships interned at the British naval base Scapa Flow mysteriously disappeared…
More than two decades later in 1940, the world is engulfed in a new war against the Mundus Empire, an invading force from another dimension. Having conquered the Southern Hemisphere and steadily expanding its territory, the Mundus Empire has finally set its sights on the Northern Hemisphere.
The United States Pacific Fleet is annihilated off the coast of Hawaii, and the Imperial Japanese Navy’s vaunted Combined Fleet suffers a crushing defeat at the hands of the Mundus Empire’s fleet that has invaded the Truk Islands.
Cornered, the Combined Fleet is relieved by the arrival of a secret fleet of battleships and warships that were supposed to have been sunk as targets under the Washington Naval Treaty, including the battleship Tosa and the German ships that scuttled themselves at Scapa Flow.
Resurrected and transformed by the Magitek Research Department, these ships and weapons are Japan’s new hope against the otherworldly invaders.
Rise, scuttled fleet!

Summary
An anthology of various works that I’ve made. None have yet to be committed to a full work on its own, so these short and unfinished pieces are taste test for possible new works.
From unusually alien roommates to creepy otherworldly customers, dip into a mix of sci-fi centered and reality questioning stories that have scratched my itch for ideas that ask “What if?”. This overall work will act as my outlet for my ideas that could possibly be put into full creation.

Summary
In the face of an unknown threat, the Avengers rose to fight a battle whose outcome would decide the fate of the entire world. In the fight against Thanos, there was no question of equal odds, so they had to rely on cunning and stay one step ahead. In the race to acquire the Infinity Stones as quickly as possible - the only things that guarantee victory - both sides are desperate and willing to make sacrifices. As failures pile up, allowing Thanos to obtain five of the Stones, a desperate Tony uses a new prototype of a machine that has been steadily developed over the years to travel back in time and steal the Stones before they fall into the tyrant’s hands.
It is a shame that Tony did not account for one more factor that could determine the outcome of the battle - his sixteen-year-old son Peter, who, while following his dad stealing the Tesseract in 1970, accidentally altered the course of events, triggering a catastrophe whose consequences may be at least… weird.
In short: a humorously toned Irondad story with elements of mild darkness, in a bit different interpretation :)

Summary
W obliczu nieznanego zagrożenia Avengersi poderwali się do walki, od której wyniku zależał los całego świata. W walce z Thanosem nie było mowy o wyrównanych szansach, dlatego musieli użyć sprytu i wyjść o krok naprzód. W wyścigach o jak najszybsze zdobycie kamieni nieskończoności, które jako jedyne gwarantują zwycięstwo, obie strony są zdesperowane i gotowe do poświęceń. Wraz z kolejnymi niepowodzeniami, przez które Thanos zdobył pięć kamieni, zdesperowany Tony używa nowego prototypu sukcesywnie budowanej od lat maszyny, aby cofnąć się w czasie i wykraść kamienie, zanim wpadną w ręce tyrana.
Szkoda, że Tony nie uwzględnił w swoim planie jeszcze jednego czynnika, który może zaważyć na losie walki - jego szesnastoletniego syna Petera, który podążając za ojcem kradnącym Tesserakt w roku 1970, przypadkiem zmienił bieg zdarzeń, wywołując katastrofę, której konsekwencje mogą być co najmniej... dziwne.
W skrócie: nacechowana humorystycznie historia Irondad z elementami grozy, w nieco innym wydaniu :)

Hay cosas que cambian sin avisar… los rostros que nos acompañan, lo que amamos, incluso quiénes creemos ser… y aceptarlo es parte de vivir… Pero hay otras cosas que simplemente suceden… Como aquel día en que el Imperio descendió sobre nosotros y, sin remordimiento alguno, decidieron que era lo mejor para nosotros

Summary
Hal was angry about many things today: an alien invasion happening while breakfast-in-bed rituals were being enjoyed, Bruce knowing his Lantern ring's size like the freak that he is, and the fact that all of this was happening while he was wearing pink flannel pajamas under his uniform, and his breath still smelled like barely-10-second mouthwash about 2-hours into the fighting and the rescuing.
Bruce apparently think it's the most romantic thing they could be doing...
...that fucking loser.

Looking back on it, it was ironic. Izuku's life would be forever changed on what was indisputably the worst day of his young life. Suicide baited, attacked by a villain, dreams crushed by his idol, yelled at by some Pro-Heroes, time portal opening, and-wait, WHAT?! Who are these two kids who just got thrown into his lap?! And why does she look like Kacchan?!

PLEASE HELP! LOOKING FOR THIS FIC by chrisch00

Summary
Hi, I searching for a fic I read some time ago and I can't find it anymore.😭 Please, can someone help me find it 🙏❤️
So in this Fic the Team Cap is still on the run and Peter and Tony are the only ones fighting in New York when it's attacked by aliens. This attack goes for quite sometime (or they are attacked again and again - I can't remember) and at some point Tony is badly injured (I think he is in a coma, because he can't give any help/input from the sick bed). So Team Cap is asked to come back to help with the fighting.
Peter and Steve are the co-leaders in the fight and everyone thinks Spiderman is an adult because his identity is still not revealed.
But after the fight is won and everyone helps with the clean up, Peter has to go back to school and also help with the clean up (because nobody knows he's still a kid). And so he is totally exhausted all the time. MJ and Ned push him to reveale himself at least to Steve because he gets along well with him and somebody should know. Because the avengers are getting annoyed with Spiderman for only help with the clean up for a few hours in the evening.
