who could this possibly be?

Isaac was a young child living through a deeply troubled family situation. His mother became extremely religious and came to believe that Isaac was sinful and needed to be "saved." His father eventually left the family, and Isaac blamed himself for the fighting between his parents. His fear and imagination transformed these experiences into the enormous nightmare represented by the game. At some point, Isaac dies, with the game strongly associating his death with hiding inside his toy chest and suffocating. The entire Basement adventure can therefore be understood as a nightmarish, symbolic version of Isaac's final experiences and memories, rather than a conventional literal dungeon crawl. And the final ending gives him something he desperately wanted: a different story. Not one where his mother hunts him. Not one where his father leaves. Not one where Isaac thinks everything is his fault. But one where his parents are together and his family is happy. That's what makes Isaac's story especially tragic: beneath all the gore and ridiculous monsters, he's ultimately just a little kid trying to make sense of things he doesn't understand. Now, Lilith is essentially one of the identities/aspects represented within Isaac's world. The playable characters in The Binding of Isaac aren't necessarily meant to be a literal group of people sharing the Basement. The game's story increasingly frames the characters as different representations of Isaac's imagination, fears, memories, or possible identities. Lilith, (she/her), is a maternal female demon figure who is more than 5 centuries old, her symbolism is associated with demons and supernatural forces, her imagery revolves around demons and familiars, and represents a twisted motherhood, also known as the mother of demons herself. She carries a demonic baby attached to her by an umbilical cord, which she uses as her primary weapon, but she doesn't mean to look scary to people. If there are more than Cain, Jacob, Eden, Isaac, Azazel, Apollyon, blue baby, ???, and others in these depths.

Lilith is depicted as a small, humanoid female figure with a distinctly demonic appearance. Like the other characters in The Binding of Isaac, she has a kind of cartoonishly crude design rather than a more realistic anatomy. Skin: Her body is a dark reddish/purplish color, giving her a distinctly demonic appearance. Head: She has a relatively large, rounded head compared with her small body, following Isaac's exaggerated proportions. Hair: She has a very long crimson red hair framing the sides of her head. Eyes: Her eyes are covered by a dark white blindfold. This is probably her most recognizable physical feature. You don't normally see her eyes at all. Horns: She has small dark horns protruding from the top of her head, reinforcing her demonic identity. Mouth: Her small mouth is visible beneath the blindfold, with the somewhat unsettling facial expression characteristic of Isaac's sprites. Body: Her body is small and somewhat rounded, with short arms and legs. Clothing: She wears a simple dark-colored outfit, with bandages as her bra covering her curvy chest, and cream colored stockings and shorts. Unlike most other characters in the dungeons like Cain, Jacob, Esau and many others, Lilith cannot see normally because of her blindfold. It's not simply an aesthetic accessory, either. Her entire combat design is built around the idea that Lilith herself doesn't directly fire tears. Instead, her Incubus mirrors her attacks. This makes her visually distinctive: while Isaac is normally shown crying and shooting tears himself, Lilith is portrayed as a blindfolded demonic woman who relies on her supernatural companion.

Floating near Lilith is Incubus, her characteristic demonic familiar. Incubus resembles a smaller, dark demonic version of Lilith/Isaac's familiar creatures, with a roughly humanoid shape, dark coloration, horns, and a sinister expression. The important visual relationship is that Incubus follows Lilith around and effectively acts as her offensive counterpart.

She is motherly though. Lilith is the Hebrew name for a figure in Jewish mythology, thought to be derived from Mesopotamian mythology. Although Lilith is only mentioned in passing in the Biblical Book of Isaiah, later Jewish mythology expanded on her. In some stories, Lilith is the original woman God created before Eve. She refused to become subservient to Adam and left Eden; in others, she is depicted as the bane of humanity when Adam refused her, driving her to curse all of his descendants and targets children under her grudge.
