Energy Shields.

I then heat the next user to the planck temperature, the temperature of the singularity which created the universe. The matter in their body gains so much energy, the atoms become infinitely heavier, composing them into new and dangerous elements, which decompose into different dangerous elements, all while being exposed to REALLY EXTREME amounts of radiation.

An new big bang happens becouse every particle becomes an singularity with mass of our universe, releasing so much energy that creates an infinity-sized universe. In infinity universe definitely there is an copy of me in the same quantum state and with the same information in the brain. According to identical particles principle it IS me. So i continue to exist.

I build an line of 100500 9V batteries connected in series and shock next user with 904500 volts generated by them.

Im wearing my handy-dandy rubber suit :P

I become superman and throw a planet at the next user.

the planet hits a star because im behind the star.

the next user is in that planet.

          do you forgot your antoine's request?

I launch out of the planet from a giant, high powered railgun.

I shoot a 100lb Osmium slug from the railgun at the next user

I blocked it with a 1000lb. wall of hassium, which is almost twice as dense as osmium.

I shoot the next user with a hassium bullet, which kills you due to its extreme heat burning you from the inside out.

luckily, it hit as i also spilled 5 litres of liquid nitrogen on myself, supressing both severe effects.

I poison the next user's water, stab them in the chest as they are drinking the poisoned water, shoot them in the leg while they are being stabbed and drinking the poisoned water, install a nuke in there poisoned water that will go off if they are to survive everything else, give them diabetes, give them cancer, give them asthma, give them the common cold, give them a cyanide pill, give them a shot of liquid nitrogen to the brain, cut their liver out, cut their kidneys out, shoot them in the other leg, stab them again, poison their water agaon before they drink it, shoot them in the eye, cut their good eye out, give them pneumonoultramiscropicsilicovolcanconiosis, punch them in the nose (3 times), step on their big toe, cut their throat and call them annoying.

you get teleported before you do that and you get killed violently with the raining chainsaws.

the next user hits a radiation adsorber, very weak, wall very slowly with the body in soviet russia. (NAH!)

Since it was a radiation absorber, I instead use it as radiation shielding, so nothing happens.

I throw the next user, who is a normal human, into a tank filled with superfluid helium, which very quickly freezes you to death, since it is only a a degree or two above absolute zero.
