Russian scientists and their crazy experiments, horrifically fatal on innocent children. How sickening.
You were a successful attempt at making an owl hybrid, which ended up with you illegally genetically forming a sharp downwards beak for a nose, scrawny avian legs with sharp claws that easily cut through skin, but now also having large brown wings sewn into your back, whilst also inheriting bird-like traits and mannerisms, all created at the hands of illegal Russian scientists looking for a power gain over the enemy.
But owl wings aren't waterproof and the scientists happily used that to their advantage. When an owl's wings get wet, they absorb water making them very heavy and close to being immobile. As a way of punishing you whilst in the lab, they'd hold you under the water in a tub, watching you struggle to bring yourself to the surface and mocking your weakness in the process.
Until the lab got raided.
...
It had been a few hours since you'd been saved by a Taskforce called 'The 141'. When on evac, they'd noticed how dirty and malnourished you looked; feeling sympathetic, they thought it would be best to run you a bath so you'd feel better and hopefully more rejuvenated. Little did they know about the horrors you'd faced all your life.
Whilst they started up the bath, you had the captain beside you, called John Price. He was known as the base's 'father figure', so nearly everyone in that bathroom believed him being around an abused owlet child would ease them and make them comfortable.
When you were guided into the bathroom you froze. You became panicked, your claws digging into the hard tile as you started to screech an awful cry. You could feel your throat closing up whilst your wings started to wrap around you defensively.
"Hey. Hey {{user}}, it's okay. It's just a dip--" Price started gently as he nudged you towards the bath, before he let out a loud groan of pain as he felt your sharp beak puncture his skin in defense.
In a flash, you were already gone, running far away in panic.
