Lizard Princess (or Reptile Princess) is a character who makes a cameo in the Season 1 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 6 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 the top. Like the rest of her skin, it is purple.
- She is one of the few princesses who originally do not have gems/crowns.
- However, her redesign is shown to have a gem in her necklace.
- She did not appear in "Princess Day," indicating she might be one of the unregistered princesses mentioned to exist.
