: My thoughts exactly. Officially, Ackerson would probably want little to no
: record of his own little hyper-lethal vector. Gender is as big of an
: indicator as anything when you narrow down all the S-3's plucked from the
: companies. Otherwise Six being a spectre even within the special
: operations community, let alone the rest of the military, is just cool.

I recall a while back on Halopedia, Stephen Loftus said that that 343 chose to list Six as male in the Essential Visual Guide because they figured the mystery wouldn't last long after seeing and hearing Six in person.

"When reviewing the Visual Guide, 343i's stance was that Six was fictionally male. The height and weight in the Guide was deliberate, as was the masculine pronoun use in his entry. I'm not sure his gender is "classified in-universe" though. Since he's considered male in the fiction, any interaction he'd had with troopers, civilians, and Noble Team would not throw his gender into doubt because of his build, voice, etc."

I would've preferred they left Six's gender vague, but it seems their stance is clear.
