I believe I've used mostly he/him and also they pronouns. Never specified gender. That might be confusing.
Fact: Wicke is a he/him in civilian form, a he/they villain outside of the suit, and a he/they/it in the suit. To me it is not about the legitimacy of changing pronouns, or of it pronouns, or equating gender to villainy. In fact for Wicke it only partially has to do with gender (he considers himself a man, or sometimes, still tries to). I love how significantly gender interplays with your MC's narrative (the most I've seen in any choice game), but I also love the blurring of lines between identity and perception. For Wicke the blurring becomes a spectrum between his sense of being a man, and of being inhuman at all. Which is very much an aspect of still figuring himself out beyond the scope of gender, while still being relative because of his sense of not being able to have one due to the nature of his birth/his species- less than agender, but an uninterpretable and alien thing. It's also an aspect of living several lives and in what ways/how deeply those separations can run, and of how they see themselves/how they imagine people seem them as a villain. Throughout all this, his presentation is male.
Fact #2: Wicke is an AFAB with an AMAB puppet, but has very low puppet individuality. The puppet is just a conveniently male body to use, very useful but totally disposable. Tries not to rely on it too much. This is to say despite any relief from dysphoria, the relief does not feel real or satisfying- his own body feels real to him, and as dissatisfying as it is the trauma of living in it is his own. Wicke is not Wicke without trauma. When he reveals the truth to Mortum, he uses escapism as an excuse, which is about the only time that's most truthful- only because it came to a relationship, which he feels he cannot have (yet) in his body.
Idk man. This tale is rich for exploration. Not just of gender itself but how a traumatized individual relates to it and similar themes. Brrr
