Frank

Frank is a mildly psychotic A.I. usually portrayed by crazy looking 'smiley face' on a small handheld device / tablet, with robotic legs and claws. He travels around, mostly unhindered, by wifi, bluetooth & satellite, where he stores himself in harddrives and RAM. Frank is the creation of Amin Rahim Kareem (whom Frank regards as his "daddy") and follows his creator around as his permanent companion and electronic defender, being able to take over weapons that are connected to the grid.
