Parasitic-Sz.L's backstory: The beginning

Before becoming an Impostor Parasitic-Sz.L often ended up being the one doing all of the more difficult tasks despite many of them being the type that requires physical strength which she just didn't have at all so she could never finish those tasks on time and always got berated for that after which she always hid behind the big table in the Specimens room since she felt safe there as no one ever thinks of looking there for her.
However, one day after another berating and hiding behind the big table in the Specimens room she noticed an interesting looking little creature inside a jar that seemed to be calling to her with various clicking and chirping sounds which it continued with like it was trying to talk to her and surprisingly she was able to understand the small creature.
She understood that the small creature wants to help her as it can feel that they have a lot in common and could help each other to become stronger, but in order for them to do that she has to let the small creature inside her body which was very painful process as her right eyeball literally had to be fully removed so the small creature could take its place but for her it was worth going through that as that pain was nothing compared to the torment she went through for many years.
Once they fully merged she had become strong enough to take revenge on those who have tormented for years thanks to the small creature's help, but once she was done killing everyone she noticed that she was the only person left on Polus, though she wasn't alone since she had the small creature that she decided to name Izo with her.
A few days have went by after killing all of the Crewmates she have noticed some changes happening to her as she have started to enjoy being in the vents/holes that can be found all around the base.
Weeks later she began to crave the flesh of the Crewmates whose bodies didn't rot thanks to the cold weather of Polus so she had plenty of food to eat but knew it won't last forever so she worked on fixing up a broken escape-pod in order to be able to leave Polus and find a ship with a Crew on it that she could join and hoped she didn't have to kill anyone amongst them.
