I use the shockwave from a small nuclear bomb to propel myself out of the pit, since it is stronger than the downdraft.

 

The next user is trapped at the end of the universe. Teleportation to other universes is no longer possible due to the lack of any energy sources strong enough to accomplish it, time travel can only be done by the last remaining black holes, which will evaporate away very soon after, and it can only send you further into the future. In addition there are no planets capable of supporting any form of life.

I am god and change the black holes into planets

 

The next user was in the same scenerio but is a normal human

I digitize myself and use a tachyonic antitelephone to teleport into the past.

The next user is attacked by a swat team

Myself, being a ninja, am able to not only hide and escape them, but tie them all up and take their weapons.

The next user finds themselves in outer space, being pulled into the gravity of VY Canis Majoris, without any type of thrust to pull them away. Your teleporter has already melted.

You know. an Extreme gravity bends place and time. I teleport back and put you to sun.

An user below is attacked by clones of Lord Voldemort, without any weapon

I kill them with my bare hands.

The next user contracted mortal greyscale (as in the Song of Ice and Fire series)

I don't know what it is so it doesn't exist.

The next user is tied to a concrete road and is ran over by a Ferdinand's tracks. Your bones get crushed completely and your internal organs are being squeezed out of your body, including your brain and heart.

bubdan no time travel other than blackholes. Oh well.

I'm mr fantastic and bend myself back into normal.

 

The next user is a normal human and is hit by a train, steamroller, nuke, planet, star, neutron star, supernova and a tornado all traveling at 500 km/hr

They all collide so fast that they transform into a black hole with a life of 0.00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001th of a nanosecond and vanish, leaving me unharmed somehow.

The next user is trapped in a pyroclastic flow travelling at 200km per hour and is around 1010 degrees Celsius while being a completely ordinary human being with no super powers or equipment and no heat resistant clothing or any form of protection.

I call for superman. He saves me, despite severe burns and many, MANY, months of recovery.

The next user finds themselves in the same position, with no superheroes to save them.
