The Immortal Yaksa is inspired by the character from the Ramayana, also known as Thotsakan in famous Thai literature. He is depicted as a mighty titan with ten heads, each representing different aspects of his personality.

In one account of Thai literature, Thotsakan performed a ritual to become immortal, conferring great powers and fearlessness in the face of death. He also combined his strength with the yantra, a mystical symbol of protection, present in all eight directions, giving him extra protection against danger. The yantra is popular with Thai and international tattoo enthusiasts, renowned for its multiple protective properties. Combined with the Thai words "คงกระพัน" (Khong Kraphan) on the front of the shorts, it symbolizes resilience in the face of any danger, making these shorts truly incomparable.
