The Powder Toy

I am made of an antimatter version of strange matter, do to which I simply absorb your mass by converting you into strange antimatter.   I touch the next user, who is made of regular matter.

Fan (What the poop hits.)

I happen to be the Earth, meaning the collision makes a new moon.   The next user was on the side of Mars facing Earth at the moment of collision.

However, since it is a dream world, the two halves of me grow into two whole dragon.   The next user is on a rocket in Kerbal Space Program, except it blows up on the launchpad.

It could undergo fusion into NBLE at 25 pressure and 1000 Celsius.

I reach 99,999, but then I throw a piece of antimatter at Superman, destroying him.   The next user was fried by the radiation released by the explosion.

@JMBuilder (View Post)  Last I checked, deuterium is a stable hydrogen isotope. Tritium on the other hand, is a radioactive isotope, that decays into helium.

@TPTROXRLYITSTRUE (View Post)  Fortunately, the plutonium-lead alloy was in its metallic form, so it passed through my body without doing significant damage. @AngrySpam (View Post) However, even...

I fire my only bullet at such an angle that it goes through both the bomb and the dragon, destroying them both.   The next user is fed to a pack of velociraptors.
