Queen Reptilla, or simply known as Reptilla, is the main antagonist of the 2005 animated film Kong: King of Atlantis. She is a human/snake-like sorceress and the tyrannical ruler of Atlantis.
She was voiced by Daphne Goldrick.
When Reptilla tried to conquer the world, Atlantis was sunk by the original Kong, who was the true king of Atlantis. Reptilla stayed in Atlantis, awaiting for Kong to return, or find a way to conquer the entire world.
Kong: King of Atlantis
Reptilla observed through a probe with Lord Sycophis, that Kong had been cloned, and she saw an opportunity to have been be hailed king and make him serve her. She ordered Sycophis and Minion to bring Kong back to Atlantis, so that he could unite them.
When Sycophis caught Jason, Lua, Tann, and Zeelah sneaking into the queen's palace, Reptilla manipulated King Kong in thinking that the group only thought of him as a pawn. Reptilla ordered Sycophis to imprison the group and the animals from Kong Island, and controlled her slaves with mind bands.
Reptilla planned to give Kong a crown that contained a mind band, so that she could control him. When Kong realized that Reptilla was evil, she sent giant reptilian monsters after Kong and his friends, but they were defeated. Reptilla tried to retreat, but collided with Minion, causing her mind control gem to fall off her forehead, releasing all those brainwashed, including Minion, who chased after Reptilla to take revenge on her.
Though her fate is left unclear, Zeelah thinks that she is still a threat, electing to stay behind to help the rebels defeat Reptilla. It could be that Minion either killed Reptilla and she didn't know about it, or Reptilla escaped and continued to command those loyal to her until she was inevitably defeated by the rebels now that she was outnumbered.
