Behold Abaddon's spouse, Sheol of the Abyss. They were married millennia ago as part of a plan to unite the demons of “civilized” Hell and the demons of the Abyss. Back then, their marriage was unimportant to them, and they were essentially roommates until Abaddon was trapped on Earth.
By Hell's laws, Sheol is now in charge of his duties and they are extremely overwhelmed -- so once they find out where Abaddon is, they decide to annoy him into leaving the Undervale and returning to Hell. Because there's no way he'd be stupid enough to get himself trapped in a child's body. Unfortunately, he is. But this turns out to be a blessing in disguise for them.
Sheol's genderfluid, but their pronouns depend on what vessel they're possessing. In contrast to Abaddon’s love for physical violence, Sheol and her family delight in psychological torture. To ensure everything is kept PG, Sheol also inhabits a child's body -- which she acquires through her very own cult.
