Though they don't look like they're related, they are. My two Hell-Hound characters, Akumu & Ai.

Akumu is the Saluki hell-hound based off of hatred. Using people as hosts to get what he wants, and when everything is said and done, many people are left dead and he moves onto the next person. Filling their hearts with hatred and darkness and promising them power they cannot control.

Ai, is the Cocker Spaniel hell-hound/Succubus based off of love and lust. She enjoys being used by others rather than controlling them. She'll find a male (or female) host, seduce them into leaving their life behind, give them anything and everything they want of her and when she has their heart, she'll disappear. Leaving them alive, but emotionally drained. Only they can choose what happens next. She also has an anthro form and is trying to be more human to attract more hosts.

Akumu dislikes his 'other half' due to the fact that she lets her hosts use her, she wants to be more human, and the fact that she lets them live at the end. (He prefers the bloodshed.) Ai holds a lot of fear for her 'big brother' because he can over power her so easily and is so much bigger than her.
