What do you know? Chuck Norris ends my curse, returns me to our dimension, Gets me out of the box covered with concrete, gets me out of the giant star, He reversed time to stop the star from becoming into a supernova, Kills the aliens , stops the black hole , Reverses and cancels everything you put on me.

I am from an antimatter version of your universe, so I escape in the same way you did, except instead of Chuck Norris, I am cured of the curse by an equivalently powerful person with a different name.

The next user is in the same situation, except that Chuck Norris, who is made of regular matter, decided to attack the antimatter person.

The two versions of Chuck Norris collide and cancel each other out. The power of the explosion sates the hunger of all antimatter and singularities in the area.

I decide to stay where I am in suspended animation; making me in the safest person in the universe.

The next user was standing between the two Chuck Norris when before they collided.

However, the two Chuck norrisses crashed into my clone made of DMND, so the chuck norrisses are still trying to collide forever.

The next user was stuck between a chuck Norris and the dmnd clone, crushing you.

I convinced the dmnd clone to kill Chuck Norris for me.

The next user is radioactive, and is poisoned by radiation. All treatments for radiation and radiation poisoning are placebo.

I create a treatment which is real, thus making me not poisoned by the radiation.

The next user enters a wormhole, thus making him unexistent.

I always carry around a large mass of negative matter, allowing me to open the wormhole wide enough to come out through the other side (a wormhole), which is somewhere in Bangladesh.

The next person is thrown into a vat of Hydrogen Chloride.

My leg explodes and bits go everywhere. I survive with a bandage.

The next user slips on one of those bits, and their head lands on a nail. 

edit: pointing upwards (I learn from my mistakes)

I am wearing a helmet, thus destroying the nail.

The next user falls into an aquarium tub of Sodium Hydroxide, but cannot:

1- Summon Chuck Norris or anyone powerful enough to stop you from getting burnt.

2- Wear a protective suit.

3- Use antimatter, negative matter , black matter, Magic.

He is also:

1-Paralyzed.

2- Too hurt to summon or use anything to help him out of this.

3- Out cold with a moose tranquilizer.

4-Cursed with an irreversible curse.
