His family was in danger once again but this time he wouldn't allow anything or anyone to harm them. He would keep them safe. Can Donnie keep his family safe? We'll see... This is a villain Donnie au Sorry in advance for any grammar or spelling errors. There will be a lot of violent descriptions as well as heavy topics. Remember no shipping the brothers in the comments!! These are brothers and minors!!! Comments will be deleted and you will be blocked!!!! The story is also on Ao3 (username: @crispy_panda) Updates will be posted on Tiktok (Username: @crispy_panda) Enjoy 😉

Donnie finds himself in a confusing and terrifying situation after the group splits up and his solo mission goes wrong, no one can find him and he won't reply to anyone's messages. There are few clues about where he could've gone and where he went is up for speculation to family and friends. No one knows where he is except for Donnie himself, who was taken by scientists. They seem to mean well, but don't see him as a person. (TW: Major character death) credit to @Mr_Lambert for helping me with many ideas, including what the theme of the story should be, and working on a bit of the content directly.

Leonardo noticed three things when he first opened his eyes: 1, there were orange fairy lights above him, softly glowing. 2, someone had lit a candle, a faint smell of citrus and pine filled the room. And lastly; There was a sword pointed at his neck. That probably should have been the first thing to take notice of. Really. But still, slightly tilting his head and lifting his eyes up he follows the sword to its holder. He then met direct contact with..
