Hitman wars! Well, I have an RPG, so I blow up the other hitman.
The next user is teleported back in time to the middle of the last ice age, only they are teleported to the center of the glaciated region of North America as well.
I withstand all the coldness and start digging down into the ice. I reach very cold water and find food. After i find food, i start dividing myself, make another clone of me. We both start finding food again and divide again and again until i have my own population and since i am a alien, i can live for billions of years.
The next person is faced by 6.5 Billion aliens with tough green scaly skin and 8 tentacle legs spiked at the end.
You, however is armed with just a wooden sword. I am armed with 8 sharp swords and can spit a very strong acid that can burn through about everything like obsidian.
But i am a weapons master, i fight prefectly, not committing any error, i then make an anti-acid armor and weapons from the scales and spiky tentacles of the first alien i kill, i then proceed to kill the 6 499 999 999 remaining ones.
The next user is not a weapons master.
I happen to be slightly more massive than the black hole that I'm falling into, so I simply become a larger black hole.
The next user is crushed into a neutron star.
i am a hologram..and i just go right through.
the nexs user is 4 inches away from a full power afterburning jet engine, about to be sucked in...
However, the operators decide to pull out a fuel rod for isotopic analysis, so I just escape through the opening in the reactor that they opened.
I place you in a sealed nuclear bomb that is now falling towards its target, with you in it, and no way out.
I eat the nuclear stuff inside and store it. I drop on the target at high speed killing him, then i burst out with my alien claws. I travel around the world and find you. After i found you, i release a giant laser beam with the power of the nuke i have been storing into your face.
The next user is going to be laser beamed in the face with the power of a nuke.
