I begin to tame all micro organisms in my area and use them to constuct a working time machine that runs of the energy that they put off

 

The next user will wake up in space without a helmet on

I was in a space station with oxygen in space. 

 

The next user is a normal antimatter being in the core of the sun with no way to escape.

Fortunately, the Sun happened to be made of antimatter as well, and I am composed of antimatter plasma, so the heat and radiation do not harm me.

 

The next user is a ball of plutonium that is about to be used for a nuclear bomb test.

I am an untested isotope, with a half-life of less than 10 seconds. I rapidly decay before I can be detonated.

 

The next user is chained up and about to have a pile driver turn them into a red, wet mess.

The pile driver and the chains for some reason were made of potato chips. I eat my way out, but in the process my shirt was stained with ketchup. LOL.

 

The next user is an rapidly decaying bar of ensteinium. 

 

In a parallel universe, Einsteinium does not exist.

 

The next user is a degenerate who dies falling off a window with a bomb attached to him and the bomb detonates after 0.3 seconds.

well then, stay die now.

i am a"Degenerate" not degenerating, so i am a verb, and it can't kill me. (the only way to kill a word is to change the word and/or the meaning)

the next user is trapped with 1000 blenders inside a bouncy room.

The blenders are stationary, and things only bounce in a room if they are already moving (excuse the lack of technical language)

The next user is tied up and thrown in to a ketchup sea _yumm

The ketchup sea was frozen, so I landed on a strange red icy surface instead.

 

The next user is thrown into a vat full of hydrofluoric acid, which starts dissolving your bones almost immediately, since hydrofluoric acid quickly permeates through flesh.
