Galactic Patrol Lensman (GALACTIC PATROL レンズマン) is a Japanese anime television series based on the Lensman novels. The 25-episode series aired from October 6, 1984 to August 8, 1985 in Japan.

Harmony Gold USA dubbed a compilation of the first four episodes in a heavily edited form, which they released under the title Lensman: Power of the Lens. The other episodes were never dubbed. This compilation is no longer available on video, although it was available in the UK in late 1980s. Despite sharing character and organization names, as well as central themes common to the books, artistic license produced a final product altogether different from the source material. The series was broadcast in Spain by TV3 in 1994.[2]

Although it was produced with the knowledge and consent of Smith's estate, the executors were so displeased with the result that for several years they rejected any other suggestions of adaptation.

Really bad series but I love the Lensman film so much....
I purchased the laserdisc box set expecting greatness.
Has it's moments though, looking back.
