Self-Destruct Button

''Q: Oh, why did I install that button?

A: Because you're stupid.

If the heroes can't destroy Villain's weaponized machine, they could hit the Self-Destruct Button. It always destroys the machine in a single go. Bonus Points if they kill or seriously injure Villain in the process. More Bonus Points if they already badly damaged the machine before pressing the button, thus making it very unnecessary to press it.

This UnTrash is notable for being very counterproductive, irresponsible, and plain stupid. Why would you install a feature in your machine, weapon, or vehicle that causes it to pretty much do the mechanical version of committing suicide? Is it so you could trap Hero inside, press the button, and kill them off easily along with yourself? Even then, it's not worth it as you still die. The blast from the explosion would most likely make an Escape Pod-aided escape worthless as it's too hard to get out of the range of the explosion in the short duration of time you have to do so. So when you die thanks to your self-destruct button, just remember that It's All Your Fault.
