I gain shapeshifting superpowers.

The next user enters the toilet after me.

I go poop and take it and through it at the next user.

The next user enters the shower after me.

What's with these bathroom attacks?

I send a clone into the shower, armed with a hidden nuclear device which detonates, destroying the area.

The next user is standing ten feet away from ground zero at the moment of detonation.

Behind a reinforced wall with kevlar, titanium, and other materials.  I am also in a juggernaut suit.

The next user must steal the tsar bomb while it is flying through the air.  HAVE FUN!

 I teleport it using my skills

I teleport it to the next users house, where it inevitably detonates above the next user's pet cow and him/herself

I shrink it down to the size of a marble and delay the detonation. The blast power is unchanged.

I teleport the shrunken tsar bomba inside the next user's heart.

Stares at it until it's close, then moves out of the way.

_______________________________

I drop knives and a lit bomb on the next person.

Too bad I'm testing out my newest invention, which returns the attack to its sender.

The next person has been turned into a black hole.

And?  Ok, well I happily live the rest of my life as a black hole.

The next user is sucked in by me, DEFINITELY>
