[quote][b]Posted by:[/b] flamedude I'm still having a hard time figuring out why a robotic weapon system would need a glowing human skull..... be it physical or holographic..... why would that ever be useful to a weapons platform?[/quote] Maybe because they're part Forerunner? If they became synthetic beings like that Lifeworker in Primordium and Chakas over the last 100,000 years, some of their form may have carried over. Forerunners did look very human; just a guess, but they could be cyborgs.
