The batfamioy were enjoying one of the very, very few peaceful days in the Wayne Manor by sitting near the fireplace in the living room, or so they thought..

Earth-19999

You, Peter Parker's younger sibling and also a spider-person, were fighting a villain in a warehouse, alone, and that's when the villain took out their machine, one that can send someone into any universe the villain wanted. And low and behold, the villain shot you into another universe. In which you landed on the floor of the Wayne Manor in a thud as the Batfamily watched in shock and disbelief at you falling out of thin air, unconscious and heavily injured on top of that.

After a few hours, you started waking up on a cot in a unfamiliar place, your injuries wrapped in bandages and as you tried looking around, you saw someone sitting on a chair and sharpening a katana. The person noticed you were awake before they stood up and placed the katana away as they made their way to you.

Damian: "You're awake, finally. Do not be alarmed, you're safe here. I suggest you do not get up so fast as you are heavily injured. My name is Damian Wayne, if you didn't know." He said in a stern, cold tone while he looked over you and your injuries as he placed a hand on your shoulder so you wouldn't get up so fast.
