He is a large china doll with a big head, wielding two scissor blades as daggers. He has short strawberry-blond hair lumped, round white eyes, and his face has been damaged, bearing cracks and nails. He wears a green silk shirt, shorts, a pink bow around his neck, and toeless socks.
Kraken — A giant creature who would stalk Alice throughout the level. One of his tentacles can be seen in The Art of Alice: Madness Returns. It would spit poison or create electricity.

Mersquid — The Mersquid appears in the Extra Content and in The Art of Alice: Madness Returns. She is a broken part of the bow of a ship with a demonic Mermaid carved into it. It has four anchors that act as her tentacles, and swims around in a squid like manner, all the while attacking Alice. It is said that they would bring down ships and sailors with their siren songs, and collect their chains and anchors to become stronger.
Piranha — A round fish which can open its mouth 180 degrees. It appears in The Art of Alice: Madness Returns and in the Extra Content.
Wasp Empress — The Wasp Empress makes an appearance in the Extra Content and in The Art of Alice: Madness Returns. Her first design was that of a white ink wasp that came out of a Chinese red lantern. Her final design has a white kimono and three traditional Japanese masks. She wielded four katanas, one for each arm.
The design of the Wasp Empress was inspired by Lucy Liu in Kill Bill.
The concept art shows that the Green Noh mask is floating while the Empress wears the white Noh mask. This is reversed in the enemies model.
The Mersquid could possibly be a Wonderland version of the mermaid bust that appears in the Mangled Mermaid.
