Soo here it is go-4 is Nonbinary
Yes I know that all the robots are Nonbinary buttt everyone else has a voice [some not all tho] but go-4 is just growling soooo that means that we can't tell if they are male or female no that don't mean that they're Nonbinary but since we can't tell they're voice I like to think they're Nonbinary but of course you can disagree bc it's just a head canon lol
