I drew the fish version of him in a pretty dress I made in dress maker on Itch.io. (with some Edits to make it look like things you can't do in the Itch.io prototype version)
Alder on his Gender/Sex:
I think Alder likes to wear dresses sometime. He was forced to on occasion when he was younger for spy reasons. Dispite that though, I think he ended up just finding them comfortable. Plus it probably makes him feel like a mom. He likes being a parent and I think sometimes he wants to feel like a mom cause for him, his mother was his world when he was little. She was a very good mom. I think sometimes seeing himself as a mom makes him feel safer, closer to her/like she is helping him in death, and that he is a better parent.
I think, Alder is very comfortable with how he presents and never really thinks about it much. So if you asked him, he'd probably just give you the most generic responce of he is male, since that's an underlying constant he feels comfortable with. Though if you asked him to explain it in depth. He'd probably say he feels very fluid and queer with it. Like there is always an undertone of he is male. But at an given moment it could be a broad mix of other things. Some more fem leaning some more vauge person leaning. Sometimes he feels he leans to spacific traditionally fem or masc concepts, like being a mother or a father spacifically (in the sense that to him, they are their own things with just vibes rather then gender spacific roles. Like they are roles in a play he can take). Just broad feelings over the undercurrent of being masculine.
Honestly the roles in a play is probably a great way to see it. He always feels like he is male underneath but that he is taking part in roles/concepts over top and the presentation varies by what he feels the spacific role/concept he is taking at any given moment calls for. Now these roles/concepts are not like traditionally based. Like sometimes his role/ concept will feel like a more masc mom or andygonous father type thing, other times it will be a feminine caregiver or a neutral worker. Just things he steps into cause it feels right at the time. I also don't mean he feels like he is putting them on like costumes and they are separated from him. No these are like things he becomes they are a part of him as they come and go. Hence why I said undercurrent of male being consistent. It's like water. It is all mixed together. It flows in and out. There is just multipal currents happening at once and one of them is just a constant current while the others change.
I think it's also based more on desire and what he wants in a moment, then what feels wrong. Like his thoughts aren't based on dysphoria by any means but more so following what gives him euphoria in any moment or what he feels is needed (for him).
He does get a sense of Envy though in very rare occasions towards those with uteruses. In the sense he wishes he could have a kid with his partner who is a cis man. He is fully content adopting though. It's only a passive passing envy when he feels super parently.
In regards to pronouns? I think over all He/Him is what he uses as his standard. Though I don't think he'd bat an eye if someone called him a they them. She/Her wise- he'd probably perfer when he isn't presenting as wholly just male in his eyes (what he usually feels and presents as). It/it's is probably also completely fine for him. There might be a scenario where the role he sees himself in prefers mainly It/It's though. Depends on how human he feels in the role.
So:
He/Him whenever
She/Her as long as he isn't his usual presentation
They/them whenever
It/it's whenever, sometimes perfered if he feels less personlike.
He'd mostly only tell you to say he/him if asked for spacific pronouns but likely clerify that he doesn't care much.
