Darcy comes up as neither as well. But his voice is definitely different to Lizzy, who comes up as female, so I feel I can safely assume he's male.

The stats/probe tools are written by people who don't have access to the internal workings of Pleo, so I figure maybe they can't always get an accurate reading on gender. Or maybe some rbs have no gender! I did a bit of research on this myself but I haven't found a definitive answer on that.
Anyway, I guess that means you get to choose Pullo's gender for yourself and nobody can argue.
