RIGHT character idea

Susie and Sean
Race: Two-headed Hydra
Age: 29
Gender: Biologically herm (each head represents as male or female)
Body type: somewhat bottom heavy
Weight: 535lbs
Height: 10' 4"
Hips: Wide
Genitalia: each one is only connected to the respectively gendered head. Sean has 12 inches long black humanoid penis with foreskin, as well as a hefty sack to match. Susie has an average sized vagina for their height.
Tail: Their tail is extremely fat as well and spans 36 inches with a feathered tip at the end.
Personality: Susie is very much dominant and commanding, this makes her come off more rude or demeaning upon first impressions, but this also makes her less susceptible to being manipulated. Sean is meek, shy, and generally more approachable than his sister. He's usually the voice reason between the two, despite that though he's vulnerable to being exploited more easily.
Notable features: two heads(duh). Susie has a set of forward-curling brimstone horns with gold embedded into them in the shape of a vine with leaves on it following to the tip of her curled horns. Sean also has a pair of brimstone horns but they're much smaller, yet still have the same gold design going to the horn tips. the majority of their scales are navy-blue but on their hips they have a gradient of scales from navy-blue to black, the top-side of their tail also has this gradient going along the top. Their forearms ~ paws and ankles ~ feet also share said black scales. The top half of susie's head is fully black whilst Sean is the opposite, having the bottom half of his face black.
