Ravis (2152)
Ravis was an alien whom Hoshi Sato met on Risa in 2152. She became intent on learning his language, which was very difficult to master. He attempted to teach his language to her, without much success. He invited Hoshi to join him in the exotic steam pools of Risa, which she did. They would ultimately have sex together. (ENT: "Two Days and Two Nights")
- Ravis was played by Rudolf Martin.
- It is possible he was the same species as Axum, from VOY: "Unimatrix Zero" and "Part II."
