Firstly, I'd suggest making this profile into a sandbox. To make a sandbox, all you need to do is go to your profile and add /Sandbox to the end of your username. In your case, your sandbox would be
https://vsbattles.fandom.com/wiki/User:BonnieTheBonnie09/Sandbox. That way it's stored in a safe place and has no chance of being deleted or anything. As far as the the powers and abilities go, explain and add a source to their immortality and self-sustenance. Unless of course, it's self-evident. Then simply stating something like (They're already dead, and thus can't die) or something along those lines could work. Whatever sounds good to you.
The "(Her Immortality makes her difficult to kill)" can be removed. It's unrelated to durability but would still be taken into consideration in matches.
Back up the sources you link to image-sharing websites. Since you only have one link in the blog so far, I've backed up the link for you, and would replace the one you're using with
this one.
Link to all feats. We can't just take your word on it occurring even if you're being truthful. Plus, if the feat is linked, it's possible that it can be calculated to get concrete statistics.
You can outright erase the "Feats" section unless you want to link a respect thread there. Otherwise, it's not necessary.
Finally, make sure all the material linked is from one canon and not fan art or anything. I'm going to assume everything you linked is canon, but I know nothing of the character, so I could be wrong.
