But im living  in 10000000000000AD when humans are indestructible.

The next person is sent through a time machine and subsequently crushed by a dinosaur during the Chixulub impact.

im a thing of bacteria and cannot be crushed by any means.

I evolve into some superhuman thing and set out to destroy the next user.

I stab you with my titanium-plated uranium sword, killing you instantly.

I trap the next user in a room made with a depleted uranium door and walls, ten miles underground, and which is quickly filling with both sulfuric acid and hydrogen cyanide gas. The door is also rigged with an antimatter bomb that will detonate if the door is opened by any means.

I am the magician, Houdini, and teleport (DON'T DARE ASK, I AM HOUDINI) out into the open world.

The next user is playing Tales of the Abyss and gets sucked into the game, turning into Ashe 0.00000000000000000000000000000000000000000000001 seconds before he gets stabbed. (BOOOHOOOO..... :"(

Ashe suddenly becomes an electron and quantum tunnels away.

Razor-sharp cards are thrown at the next user.

To bad cards are terrible projectiles an a small gust of wind blows them astray.

I, the next user, and several other users are all trapped in a fighting pit with a single weapon of our choice. We all took a solomon oath at the start of the fight not to use our powers or our abilities. (I'm hoping to start a fair fight with many users here) 

Using a dirk, I stab the next user.

I kill you all with a minigun (why'd you all bring melee weapons?)

The next person was watching, when they got hit by a stray bullet.

I was starving and ate the bullet.

The next person gets sent all the attacks from this forum.

I implode into a black hole due to the combined mass of all of those attacks, producing a powerful gamma ray burst in the process. The universe then collapses into me, and I explode becoming a new universe.

The next user is trapped in the collapsing universe, with no escape or way to stop the collapse.

 Boom, the universe collapses.

Everyone dies.

I am ressurected by some magick force.

I stab the next user with a stab-o-matic.
