The New Adventures of Captain Planet is the sequel of the 1990 - 1991 DiC/TBS Productions animated series Captain Planet and the Planeteers. After Ted Turner acquired Hanna-Barbera Cartoons in 1991 he transferred the production from DiC Entertainment to Hanna-Barbera and the show was renamed. The voice actors for some characters were changed, including the new voice of Margot Kidder as Gaia (in the first series it was done by Whoopi Goldberg). Now the two series are often considered as one, though they are distributed separately and are broadcasted as two separate shows by Cartoon Network UK. The show ran from 1993 to 1996.

The series had noticeable differences in the animation style as well as episodes revealing more of the past of each of the characters. This series doesn't directly contradict the first but expands on it severely. Gi tells the story of her pet dolphin, while Linka is revealed to have a mining family who used canaries to detect lethal gases in the mines. Dr. Blyte is revealed to have a sister who is a famous movie actress; they are possibly identical twins as Dr. Blyte in a wig is able to pass as her sister without anyone noticing.
