Bitstream is, you might say, one of the Decepticon L33T. He's a genius in his role as Information Engineer and brings to the table a skill set that can hack any target, nuke any system, and break any encryption you need broken. His greatest skill is also his biggest weakness, as he can lose himself in computer systems and virtual worlds to the point where he can't keep track of what is simulated computer space and what is reality. It doesn't make much difference to him, he's just as at home fragging Autobot jets or Autobot hard drives.
He likes to take off one of his arm guns and hold it rifle style. Just how he rolls.
His alt-mode is a Modified F-15 Eagle
