I'm hoping this is the right type of post...

Unfortunatley, the program's controls were isomorphic, meaning only I, who created it, can control it. I have the flag and I take it to a moon orbiting Jupiter.

[Robomajor]

I blow up all of Jupiter's moons and you go out into space. This of course makes you die. Luckily the flag was sent back in Earth's direction, burning upon reentry. The flag then respawns and I take it.

[Norman Bates]

Little did you know, the entire adventure so far had been a video game, nobody really died and the flag was under the control of indestructible Japanese wombats.

[Blissinged]

I get a huge MEGALAZORZ and destroy the things guarding the flag, and take it.

...under the control of indestructible Japanese wombats.

Your latest post is now irrelevant. Wombats still have the flag. Think of something clever-er...

[Ratburntro44]

Sensing a problem with my programming, SkyNet reboots. This resets my programming. The wombats, also being Terminators, give it to me. I now leave it defended by a million indestructible robots.

[Norman Bates]

I build an atomic bomb, and drop it on the robots(you never said they were indestructible). I take the flag and place it under high security with the ILLUMINATI, the most complete organization of elite people in the world.

[Ratburntro44]

Since I am SkyNet itself, I simply build more robots. I then go back in time, successfully kill John Connor (unlike the other idiots who kept failing at it), and then change my post to say that the robots are indestructible. This voids your previous post. After this, I also blow up every other universe in the ultiverse, destroy every wormhole, and fix all temporal loops, thereby making time travel now impossible. Nobody else may use time travel anymore.

Since people aren't responding fast enough, I get bored and give myself another AI. Whenever my post begins with "AlTerminator:" then it is about the other AI that I have.

AlTerminator:
I now steal the flag from my other AI. As an army of robots is sent after me to gain it back, I destroy all of them. That leaves Ratburntro44 (normal me) without any armies left. I now hide the flag inside the Death Star, which I have taken control of. If anyone is to defy me their home planet will be destroyed.

[Chess435]

Two words: Photon Torpedoes.

The Death Star is destroyed by a lone X-wing, causing the flag to respawn in intergalactic space. I summon Maxwell from Scribblenauts to write "Indestructible Reflecting Omnicidal Cthulhu" and then superglue the flag to him.
