Her picture was drawn by Kittyluvver.
Acidcreator was assisting a male NightWing scientist named Soulhunter, when he died when one of his sulfuric acid vials mysteriously exploded, the sulfuric acid melted his neck and got into his bloodstream, killing him. Acidcreator was not hit by the acid spray, but right after Soulhunter died she felt like she knew a lot more than she really did. She dismissed it and went to get someone to clean up the mess. The next day when she woke up she felt like she was not in control of her body. When she was mixing a potion that she had never made before she heard something give her instructions. A few hours later she heard the same voice in her head. "Soulhunter never dies..." She continued having control issues with her body. She found that if she focused hard enough she could block Soulhunter out of her, but she couldn't get him out of her head. She now works as the assistant of Atomsplitter.
She is nine years old and has purple underscales, dark purple primary scales, gray wing membranes, blue eyes, white horns.
