Charon is a Trion Warrior with a white-colored body and a thin red line running vertically across the middle. It has three blue "eyes" with red outlines that form a triangle, the top eye being over the vertical line. It also has three horn-like appendages, forming another triangle on the opposite directions of the eyes.
Charon has shown to be somewhat cheeky, as implied by the tone of its voice when Gieve and Kharon found Chika. It also seems to enjoy sarcasm as well, as it continued to use the "-sama" honorific when referring to Gieve even after his transformation into a Trion Warrior and it revealed that he was being used as a decoy.
- In Greek Mythology, Charon or Kharon (Χάρων Cháro̱n) is the ferryman of Hades who carries souls of the newly deceased across the rivers Styx and Acheron that divided the world of the living from the world of the dead.
- Charon's voice actress, Sakiko Tamagawa, also voices Lamia.
