I catch the apple and put it on the table.
I trap the next user on Mars back when it still had water on its surface with no way to get back to the present time.
I brought the instant earth pellet with me. I throw it into mars, creating an atmosphere and everything else on earth.
The next user is an alien on mars that is allergic to oxygen.
I go into a Martian Underground Bunker, the only working one.
The next person (why does every single person say user?) is trapped in a different bunker, where the door was intentionally meant to not completely close. They are contaminated by oxygen, and are also allergic.
Not an Attack
Next user has a grenade implanted in his head. Blows up immediately.
Hmm. Looks like the perfect time to test my EMP grenade. So I throw the grenade, causing an EMP which destroys the space core.
I throw the next user out into the middle of Neptune's Great Dark Spot.
That was an attack, as he rigged the door to not close all of the way.
Haha! Perfect time to test my EMP Anti-gravity bomb. I have implanted it in the core. It is destroyed as a result.
The next user is thrown into a black hole.
Perfect time to test my new light speed potato!
The next user encounters a strange alien army armed with a PLUTIONIUM AND THUNDER bomb.
