His full name is Harley Sawyer. He is also called The Doctor, or Doctor Harley Sawyer. He is cruel, narcissistic, and brilliant scientist who serves as the mastermind behind the unethical Bigger Bodies Initiative (which is when they turned kids into toys to try and discover immortality). He is an organic-robotic hybrid featuring a TV screen for a head displaying a single eye surrounded by purple static, long robotic limbs, and gray robes with a hood over the screen, often controlling mechanical vessels to interact. He's secretly very much in love with Guest.

She is a tan ball-jointed doll with no nose, large oval-shaped eyes with black irises, round ears and blushed cheeks, and a smiling mouth framed by white teeth. She has a long-curved eyelash for each eyelid. She has long purple and black hair that's tied in long braids that she can use to grab things. She has chaotic energy, extreme insecurity, and violent tendencies. She went insane and acts like a child despite the fact she used to be an adult human.

She is a small, 2'3" porcelain doll with chalk-white skin, rosy cheeks, freckles, and red hair in curled pigtails held by blue ribbons. She features realistic blue eyes with long lashes, red lipstick, and wears a large, flouncy Victorian-style blue gown with bows and black Mary Jane shoes. She is a complex person. While she is helpful, she can be a bit manipulative at times, while also holding deep trauma from the Hour of Joy, and a desperation to escape.

He is tall, slender, blue-furred monster with long limbs, yellow hands/feet, and a terrifying, wide mouth filled with multiple rows of needle-like teeth hidden behind red lips. He is obedient and can be curious, but he's prone to rage and will lash out when under stress. Kissy Missy can call him down pretty quickly though.

She is tall, slender, pink-furred monster with long limbs, yellow hands/feet, and a wide mouth filled with multiple rows of needle-like teeth hidden behind red lips. She's calm and doesn't attack unless someone hurts her or her friends. She's friends with Poppy and helps her get around.

He is a lion twice the size of a horse that has rainbow yarn mane all over his yellow-orange body. And Yarnaby has a split face down the middle that opens up, with his face showing two big eyes and a toothed smile, but his entire inside of his head is a giant mouth with sharp teeth. He is not very smart but VERY loyal to Harley, and often acts like a giant cat.
