Summary
Skizz is a human who's been abducted by alien pirates, but his fellow prisoner might be just the person he needs to help find his way back home. Now if only said person wasn't a lava monster with a completely incompatible form of communication.
Tango needs to escape the pirate ship he's been taken captive on, but he has no hope of doing it alone. If he can convince this strange other creature to trust him, they might just have a chance at freedom.
Zedaph has crash-landed on Earth, a very unfamiliar and very off-limits planet. A local he stumbles upon could be the key to getting him reunited in space with the partner he was separated from, without also getting arrested... if he can somehow teach them enough about the physics of FTL travel for them to repair his busted ship.
Impulse's best friend vanished in the night, and was replaced by morning with a literal alien. If this is his only lead, there's no way he can let it slip by-- rescuing someone from space would otherwise be absolutely impossible for him. He can probably find some old appliances to recycle into a decent sci-fi spaceship engine, right?

Summary
Izuku falls to his knees, gasping, struggling for air. He can vaguely register the shouting of his neighbors, the alien language coming out shrill and high pitched, even while muffled by Izuku’s own racing heart. His left hand is still holding the bars in a white-knuckled, throbbing grip, the fingernails on his right hand scratching at the metal floor below him.

Cut off from humanity and forced to rely only on each other, Midoriya Izuku and Shinso Hitoshi have their work cut out for them. Midoriya is clever, intelligent, and a quick study. Shinso knows what it takes to survive with nothing but himself to rely on. Together, they are the perfect match to make it back home. Except for the fact that they happened to be kidnapped by alien pirates, and they have no knowledge of the worlds beyond their solar system. The universe is an unforgiving place, and, as they will soon learn, an extremely dangerous one as well.What will it take to make it home? What are they willing to sacrifice? And are they prepared to leave behind the friends they make along the way?

Summary
This work is the first part of a series I am creating called OUTER SPACE. This story follows a 16 year old Martian Girl named… Cho’Khio, her name is pretty strange, I suppose. One day, she learns about an alien species that will soon come to the Solar System and tries to do everything they can to stop them, despite having near to no friends and no one who trusts her. Well, except for 3.
This story is told in the perspective of her.
Overcoming the hostile alien species, school bullies, and reprimands from skipping classes, she seems to be trusted to take down a more hostile species than the Cells. How does she deal with all of this, when her number one worry used to be getting homework in on time?
This is an original piece of work, so I don’t expect it to be too popular. If you decide to read this, thank you. I am also experimenting out using images on ao3.
Finished. 12/09/25.
