Before they kill me, I introduce them to something else that eats brains: The Zombie. Their relationship does not go so well since they both were trying to eat each other's brains. In the midst of all this, I escape.

The next user is stranded on the moon with no air tank to breathe out of.

I do not breathe air, I breathe cosmic particles.

Next user has a 3 ton (3000kg/~6000lb) weight drop on top of him with no way of not getting killed.

However, I am on an asteroid, whose gravity is so weak the the weight is only thirty pounds. I just push it off of me.

The next user is in the same situation, but they are sticky on Earth, where the weight really is 6000 pounds.

I am invincibru since I am a XP orb.

Next user is on a train, which has the Tsar Bomba explode on it, with no way of not getting killed.

I use SELF REVIVE!

The next person now gets lightsaber'd in half.

Luckily there are paramedics nearby.

The next user is forced to kill themself.

The mind breaks first, but is recovered over therapy.

The next person gets run over by an aircraft carrier running at 20 KNots

I crawl out of the runway with only a crushed foot, and no other wounds.

____________________________________________________________________

I shoot the next user below with a prot/deut blaster.

I use a mirror to reflect the beam in a random direction.

I infect the next user with smallpox, a class 1 biohazard.

However, I happen to be immune to smallpox, due to an earlier cowpox infection.

I teleported two chunks of matter and antimatter into the next user's body. They collide with each other, causing a giant explosion which instantly vaporizes the user's body.
