A pulsar that is moving at 2million kilometers per sec C: so i didnt fall on it, but it pulled me back to Earth.

The next user is mortal without suit inside Earth core. (i don't try to make my attack impossible to escape, like some people does >_>).

Teleportation devices are awesome.

User below does my black hole thing on page 454. No time machine or other devices of any kind. No sudden changes to any physics of any kind. Good luck ;)

The black hole is the nick that i gave to my friend because when he find us, we can't get rid of it xD, but it doesn't destroy me, just my patience >.< .  And please don't repeat the same attack many times and just modifying a little detail.

The next user is naked mortal shark food.

Hehe 2 posts in less than 10 minutes.

I am naked, but my skin is made of steel.

The next user is simply so cool he freezes to death.

Good thing I am made of liquid helium, which has no freezing point under standard atmospheric pressure.

The next user is a piece of sodium that has been thrown into water.

Someone opens the drain.

Next user is buried alive. Not immortal, cannot get out by ANY means. Cannot live forever, no supplies. No communication.

I am buried beneath 1mm of dirt. I simply dig my way out and begin yelling for halp.

The next user is teleported into the core of the Earth.

I said cannot get out by ANY means. And I also have teleportation device.

Next user is normal human being launched at a naked singularity, with no means of avoiding direct hit. So no teleportation or time maching. Not immortal, no protective suit, singularity cannot die. Normal universe, normal physics. Direct impact is inevitable. It's not a dream.

It is of extremely low mass, so I am unaffected.

The next user is trapped in one end of a nuclear bunker, with a Tzar bomb hidden somewhere else in the bunker, set to detonate in 15 seconds.
