The francium was just about to reach my mouth when I realized why on earth am I eating francium? I quickly toss it into the guy beside me's mouth (Who just happens to be called "The Next User") and I run away while a huge fireball erupts behind me.

 

The next user was the guy who ate the francium

I spat the Francium in the face of the next user, I abandoned the room and escape in my own helicopter: D

 

The next user was the guy who was incinerated in the fireball

I was in a tank.

The next user is attacked by a kamikaziblackholetornadohurricanevolcanotsunamiearthquakemeteorshowerfloodmissile.

 

It doesn't exist in real life, therefore nothing happens.

The next user is a grenade about to explode.

Because I'm a grenade, that doesn't matter to me. (Grenades love to be exploded)

 

The next used is a bread in the floor. (Breads don't like to be on the floor)

You said IN the floor...that is not possible.

The next user is being appled to death.

I'm Apple Jack and eat them all.

The next user is in a skyscraper on the top floor and a drone suddenly kamikazis through it, setting it on fire, blowing it up and causing it to collapse. YOU ARE AN ORDINARY HUMAN, YOU ARE ALONE IN THE BUILDING, DISABLED AND THERE ARE NO SUPER HEROES...AND NO HELICOPTERS!

Fortunately, it turns out the building was made entirely out of non-flammable materials, which means that it does not catch fire. In addition, the support structures were made of tungsten, so the building does not collapse either.

 

The next user was a normal human in the city of Hiroshima when it was nuked. You cannot survive in a bomb shelter, because they were not strong enough to resist the blast, the heat and firestorms will vaporize you, and the intense radiation levels will kill you within an hour. In addition, you are five meters from the bomb's hypocenter, which is the point on the ground directly below the bomb.

Before the bomb slammed into the ground, i will shoot with hypersonic waves attacks to the nuclear bomb and detour to the closest asteroids zone.

 

The next user is exterminated by the attack of hypersonic waves

You were a normal human so you couldn't shoot soundwaves. OOOOOOOOOOOOOH! PWNED! And nukes don't slam the ground they explode mid-air. DUBL PWN!

The next user is strapped onto the tsar bomba as it was detonated while being a normal human being with no armour, equipment or communication, teleportation or mingy-bingy sciencey abilities, no body knows you're there and no helicopters, planes, or super heroes. GET OVER IT!
