The Red Eel Monster has a very long and serpentine coral pink body with a single yellow orange stripe coiling around the entire length of it. Her head is similar in appearance to that of Nephrite's corrupted form, which is just a head with large mandibles and no other discernible features, though the Red Eel's head has the same color as her body. Even the gemstone placement is similar to Nephrite's corrupted form, which is located just behind her mouth. There's also a large red mane immediately after her head. She also has a large red forked tail fin found immediately behind her.
