The anime that you're talking about was first called Gatchaman I in the early 1970's. However, when it was translated in English, the series was entitled Battle of the Planets, often called G-Force, which ran from 1978-79. Then, Turner Entertainment's Cartoon Network created G-Force: Guardians of Space (1987, 1995), which stayed closer to the original Gatchaman series. It was when Saban Entertainment bought the rights to Gatch II and Gatch Fighter, that the Eagle Riders series was created and ran from 1996-97.
The characters of Battle of the Planets was Mark, Jason, Princess, Tiny and Keyop. <img src="/images/graemlins/smile.gif" alt="" />
