Has Tandy always been a she? I thought they were the first gay couple to get some limelight in the Schlockiverse.
She was referred to as "she" in the very first panel she was mentioned in. Rather than homosexuality, it is a strike against the "humanoid female alien with tits" meme. So far every other example of alien females look more like animals than humans.
But if you want gay stuff, I'm sure at least some of the Gavs have experimented in clonecest. I'm sure there is some identity and gender reassignment in there, but every experiment needs a control, right?
