Not as widespread as the cyborg tattoos or alien-infestation tattoos, the biomechanical tattoos depicting a monster inside the body of the the tattoo's wearer is still a quite widespread choice.
Without claiming to be exhaustive, this list contains the main themes of the biomech-monsters tattoos:
- zombie infestation (zombie bites, zombie transformation, zombies eating the body from inside etc)
- the human body depicted as the monster's hiding place
- fetuses (zombie fetuses, mosnter fetuses)
- torn skin revealing a hidden monster (usually only the teeths, the claws and sometimes the eyes of the monster are visibles) eating the body from inside
- skeletons (the entire skeleton or just some parts - usually the skull and the hands) inside the body
- demons living inside the body
