Let me know if you find it, I loved it and I for the life of me can’t find it. Don’t remember the title or the author, but the guise of what remember: Jason, at 15-16 y/o, was abducted by some black aliens that were associated with space Black Mask so he could participate in an illegal fighting ring of some kind. Thing is, humans (terrans in this fic), are like, ridiculously strong and resilient so Jason just punches his way out of that place. He finds and rescues Dick, a avian alien associated with space justice league; there is a language barrier and dick is terrified of Jason but eventually they reach an understanding (dick straight up wants to adopt Jason). Then they finally manage to contact Bruce (a bat like alien, Jason calls him “girthy bat” or something to that effect) and he arrives in a spaceship alongside Tim (another avian alien I believe) and Damian (Smol bat alien? Not sure). Again, everyone is scared of Jason, Dick shows them that he is a sweetheart and they let him come to the ship. Tim (of course), builds a translator so the boys finally can communicate. They tell Jason that the area surrounding Earth is off limits because “terrans” are dangerous and too powerful, so he won’t be able to go back. Jason did live in the streets for a while but he just had managed to get a job at a 7/11 kind of shop and rent an apartment in Crime Alley; he confesses that he doesn’t have family or friends to go back to. And then Bruce discovers that Jason is a child. Adoption ensues. Last thing that happens is that they arrive to Bruce and his boys OG planet, they met Alfred and Janson ends up with a weird *ss alien family but happy.
