Department of chainsaws for hands

I made myself a horror movie bingo card for October, and I am trying to think of a name for a trope I love.

What do you call that thing where characters have ridiculous and cool DIY assistive tech? I am thinking about chainsaws as prosthetic hands, homemade motorcycle-wheelchairs, and the other mayhem that shows up mainly in horror movies.

“Fuckin Rad Improvised Accessibility” is my draft so far 😂🤘🏻

Movie still from Planet Terror (2007), showing Rose McGowan standing in a sexy pose wearing sunglasses, a bra top, miniskirt, and a machine gun as a lower-leg prosthetic. Behind her are flames and smoke.

Movie still from Silver Bullet (1985), showing a tween boy played by Corey Haim going down a country road doing a wheelie in a three-wheeled motorcycle wheelchair. A sign on the seat back reads "silver bullet" and white smoke blasts out behind.
