Ok, but Chernobyl is fairly clear now, and not instant death. Also, bomber planes have heavy metal compounds. Metal blocks radiation(to a extent), and I simply fly the plane away.

I promptly crash the plane into the next person.

the plane crashes into my dentical twin leaving me alive. I bury the next user (an ordinary human) up to their neck in concrete in an underground bunker with no exit containing a nuclear warhead about to explode.

Fortunately, the concrete was in a dry powder form. I simply dig myself out, before taking the plutonium core out of the nuclear warhead, which turns it into a conventional explosive, which I run from, just escaping in time to see the explosion.

The next user is trapped next to a star seconds from going supernova.

I am gravity, the cause of the Supernovaing star, and such, I do not get damaged.

I crush the next user with millions of newtons

A very large box that surrounds a T3 planet (spore fans?) That im able to colonize and my colony mines the box and send a spaceship back home.

The next user has no terra forming tools and is stuck on my colonys moon, a T0 planet with incredibly hot minimal atmosphere

However, it turns out that I arrived there just in time for the place to be hit by the Staff of Life, which instantly turns it into a habitable T3 world.

The next user is a normal human who has no tools, superpowers, etc. that is being submerged in liquid hydrogen cyanide.

I regain, my powers and turn into the Strongest fox ever alive Canis Nuclea Fox. 

The next user is destroyed by me using all my, power and lives on Venus for eternity.
