1. It took me a long time, but I think Rydra is the first case of a female with more masculine traits, as she has larger than average muscles, but retains a feminine voice and genitals. The inspiration I saw gave me a concept that would make it work for me. Though Rydra wouldn't be above taking advantage of the Starmaninjian ability to temporarily change gender given her personality.
2. I was initially intending to give her plantigrade (5 toed) feet, but...I just dialed it back when it proved to be a pain to draw at this angle, but given Rydra's age is the same as Kao's, it's likely she'd just have a child born after Wolfen's generation who could be more anthro in appearance. I'll have to see when I work more on Wolfen's story.
