Lizard Princess (or Reptile Princess) is a character who makes a cameo in the Season One episode "What is Life?" in Ice King's Imagination Zone. She is located between Space Angel Princess and Mini Queen. She later reappears in the Season Six episode "Breezy." She is the ruler of the Lizard Kingdom.
She has short blonde hair, purple skin, and dark-purple curved horns. She wears a teal dress with a green belt and a gold-colored amulet with a green gem that has an "eye within the sun" design, resembling the Demonic Wishing Eye. Like most lizards, she has a tail, fangs, red eyes, and a long forked tongue. Her tail is under her dress and has spikes coming out of the top. Like the rest of her skin, it is purple.
- She is one of the few princesses who do not originally have any gems or crowns.
- However, her redesign is shown to have a gem in her necklace.
- She did not appear in "Princess Day," indicating that she might be one of the unregistered princesses mentioned to exist.
