Includes human experiments in a lab. Both the series give off the same eerie vibes; the fear of what comes next, of the unknown; the struggle against corrupt humans and others.

A supernatural series that focuses on creatures and bizarre happenings surrounding a statue as well as folklore.

Both "Taegukgi" (2004) and "Gyeongseong Creature" (2023) are South Korean productions set against significant historical backdrops. "Taegukgi" is set during the Korean War and follows two brothers drafted into the conflict, highlighting their struggle for survival. Similarly, "Gyeongseong Creature" is set in 1945 during the Japanese occupation of Korea and features characters battling a supernatural creature born out of greed. Both stories are known for their emotional intensity, complex characters, and high-stakes action, capturing the characters' resilience and sacrifices amidst chaos and conflict.

there is a high chance that they are both like the trill drama or series based on thriller with the unknown creature that makes the series very interesting and one of the famous actor also play a role as a lead character in this series

The East Palace and Gyeongseong Creature are both historical Korean dramas that combine supernatural horror with mystery, action, and emotional storytelling, but they explore those elements in different ways. Both series follow protagonists who confront terrifying, otherworldly threats while uncovering long-buried secrets that endanger many lives. They feature richly detailed historical settings, cinematic visuals, intense action sequences, and a blend of suspense with character-driven relationships. In both stories, the supernatural is more than just a source of scares—it serves as the catalyst for uncovering hidden truths and exposing the darkness lurking beneath society. However, their central conflicts differ significantly. The East Palace is rooted in Korean folklore and the spirit world, centering on a cursed royal palace, vengeful ghosts, and a spirit-catcher who teams up with a court lady who can hear the dead to unravel a decades-old royal curse. In contrast, Gyeongseong Creature is a historical creature thriller set during the Japanese occupation of Korea, where monstrous beings are created through horrific human experimentation, making its horror deeply connected to the brutality of history and human greed rather than ghosts or curses. While The East Palace leans into occult mystery and palace intrigue, Gyeongseong Creature emphasizes survival, conspiracy, and bio-horror against the backdrop of colonial oppression.

Both have to do with human transformed monsters.
