When corrupted, Lost has several changes happen to them. Besides the obvious physical changes, her natural p0$171v17Y aura gains n3G@71v17Y, as well as being no longer repressible. They still keep her light pink magic aura/glow, but it's less noticeable beneath the intensity of the other aura. Ever since her creation, long before their corruption, they have had their positivity & negativity mixed to the point of being unable to be separated or changed separately. Although this makes her immune to things such as emotional auras or the Trickster Virus, this has also left her with p0$171v17Y and n3G@71v17Y since their creation. Due to having practically an eternity with her p0$171v17Y and n3G@71v17Y, it has fully adapted to them. While this makes them almost perfect at controlling it & using it in magic (in particular, p0$171v17Y), this also makes her prone to periodic corruption; usually, but not always, long-term. This also causes a major personality change; Her natural sadistic tendencies become ~15x worse, she becomes more childish (with exceptions), and will almost constantly act with a twisted form of positivity; in particular, they will become more ignorant of boundaries, and will act more upbeat and cheerful. This is due to her p0$171v17Y, the emotion they're more connected to, being highly channeled through her personality. The way she speaks will change, too; her speech patterns will be more formal, while also being more excited & expressive. Beyond her p0$171v17Y and n3G@71v17Y magic being stronger, there will be more changes to their magic use; in particular, she will be more prone to using the stronger magic that they may occasionally forget the existence of otherwise, such as reality warping via the mind, or taking advantage of her actual nature. She's also more likely to ignore their body's code like this, living up to a higher amount of her potential- Not all of it, however, as they still refuse to do certain things they are technically able to do; instead, they use things that they acknowledge as some of their basic powers, but just rarely use. They call this corruption their SOUL overflowing, as their corruption occurs when their SOUL is no longer able to handle the sheer amount of p0$171v17Y and n3G that they produce, and ends when most of it is out of her SOUL. However, there is no way to fully eliminate her p0$171v17Y and n3G, since she creates it naturally, meaning there's no way to fully stop them from becoming corrupted again.
I FINALLY GOT THE MOTIVATION TO MAKE THIS! Linked to my previous project: https://scratch.mit.edu/projects/773958780 I edited it bcz I forgot to add an important paragraph. Edited again bcz I didn't like how the pronouns were written.
