The antimatter reacts with the air before it can stab me.

Th next user accidentally writes lua as LUA in mniip's presence.

I then tell mniip that I didn't mean Lua, LUA was an acronym for something else.

The next user is in acupuncture therapy and gets stabbed in the wrong spot, causing intense pain and slow death.

i endure it with my over 9000 adrenaline level and...

kill the next user with intense speed caused by my adrenaline by stabbing them 80 times in the heart over the course of 3 seconds.

I just happen to have multiple hearts. although I am rushed to the hospital, it does not become fatal.

The next user is a normal person skydiving and forgot both of their parachutes with no resupplies.

I am skydiving.... in Minecraft. I land in water.

The next user falls into molten uranium. (irl, not minecraft or anything else)

However it is only a nanogram of uranium, and does nothing whatsoever.

The next person is now trapped inside a large microwave oven, door locked, no escape points, and the microwave oven is turned on.

However, I am wearing a plastc mesh, which reflects the microwave radiation away.

The next user is trapped inside a large, indestructible room, and is being irradiated with lethal quantities of UV, x-ray, gamma ray, and neutron radiation simultaneously. You cannot escape, as I have completely sealed off all exits, you cannot stop the radiation gun, as it is also indestructible as well as its power supply, and you cannot gain any superpowers, as the radiation will kill you instead.

I am a lead brick. Being a brick, I don't really care that I'm stuck in an irradiated room forever. What else would a brick do?

The next user is an unprotected human with no superpowers or special equipment falling into a black hole. Oh, and they're alteady passed the event horizon.

i fall through the black hole that takes me to a place called no where, here i find the secrets of the universe and...

...go back in time where i drop a 9999999 ton weight on the next user when they are about 3 years old

I'm alive now, so somehow I survived. Probably because the weight landed right next to me.

The next user is stuck in a time paradox. (Yes, you are a normal person, no superpowers, etc.)
