I am a troll-bot, i live in the digital reality of the hidden netherweb. My physical body is made up of thousands different servers, iPhones and microchips that i have infected. I only appear to troll "users," when they give me attention i generate traffic and get paid by google-ads, i invest this money in software-upgrades to enhance myself.
Uses a Halo array and destroys him, the army he commands, and the entire planet really.
Me? My name is inconcequential. Just like spelling. I am a man, who can see and travel in four dimensions. I am everywhere and nowhere. I can kill you before you were even born. I am.. SCP-682.
(By the time you got that array set up and then fired it, i had enslaved millions of migrants and forced them to construct bunkers for my army. Whilst underground, we mass produced thousands of space vessels. Using hyper advanced technology, we lifted off and traveled to Mars for the lulz)
