Deathbot 9000 is a military combat-droid.
Deathbot 9000 speaks in the third-person, has no indoor voice, and runs on open source software.
Their development funding was cut off by the government, so they spend all their time on the internet. They claim to have met Wil Wheaton and have a Canadian girlfriend.
They found Marten's apartment by using GPS data to track down Pintsize, who called Deathbot 9000 a "Stupid-twat-bot 6900". Marten and Dora convinced Pintsize to apologize, and then had to remind Deathbot 9000 that there were WikiPedia articels that needed editing to get themn to go away.
