He fights well but I win.

The next user is a 1^-googolplex second from dead.

But thankfully I am saved by Michael238 who counts for me when I am just about to die.

The next user is skydiving to close to the ground. 

We(Radiationproof Antimatterproof Kyrptoniteproof Superman) skydive near the ground and we hit the ground.

A earthquake appears as we hit the ground but Radiationproof Antimatterproof Kyrptoniteproof Superman survives the fall.

The next user is in the highest building in the world while that earthquake happens(UNDER THE BUILDING DONT SAY "HAHAHAHAHAH IT WAS 999999999999999999MILES/KM FAR AWAY" OR THE MIGHTY Radiationproof Antimatterproof Kyrptoniteproof Superman ATTACKS YOU

The tallest building was made of dmnd.

The next user falls into a pile of thdr.

The THDR transforms Radiationproof Antimatterproof Kyrptoniteproof Superman to THDRProof Radiationproof Antimatterproof Kyrptoniteproof Superman

The next user suicides

My knife, unfortunately, is too blunt, my gun jams, and I try to fall off of a 6-inch cliff. In other words, I fail at suicide.

The next user is a dwarf in Dwarf Fortress.

I become a dwaf, but otherwise nothing bad seems to happen to me.

The next user is 90 years old, is in hospital and about to die peacefully. (and they're not superman)

This is the Adventure Time episode "Puhoy," and I am Finn, so I just wake up from my pillow world dream.

The next user is the blanket dragon from said dream. (Finn slices it open)

However, since it is a dream world, the two halves of me grow into two whole dragon.

The next user is on a rocket in Kerbal Space Program, except it blows up on the launchpad.

Just simulation

By our experimental fallacy, a antimatterial radiation exposure changes us into Anti-Superman that controls our own Anti-Universe. Then, we made a Anti-army that uses Anti-matter to destroy the next user.
