Lena may refer to these characters that appear through different adaptations:
- Lena (Manga): A young woman appearing in the "Snow Carnival" special.
- Lena (1979): A cyborg appearing in episode 11 of the 1979 series.
- Unlike the ambiguity with the Rina/Lina character, these characters' names are more blatantly intended to be Lena, owing to their German heritage. Amusingly enough, this name can serve as the short form of Helena, along with other names ending in -lena.
