Production of this show began prior to the fall of the Soviet Union. In the opening credits to the first several episodes, it is stated that Linka is from the Soviet Union. Later, the opening sequence was dubbed over to say "Eastern Europe" to stay as politically correct as possible.
Captain Planet's color scheme is based on the rings' colors, thus emphasizing the fact that he is the combination of the five powers: green hair (Earth), red clothing (Fire), white and blue skin (Wind and Water respectively), and yellow chest-piece and belt buckle (Heart).
Each Planeteer comes from a different continent, subtly hinting at the need for people of all nations to work together to care for the planet. Australia and Antarctica are the only continents from which there is not a Planeteer with a ring granting a specific power, and Antarctica has no permanent inhabitants, and therefore no one to give a ring.
The look of Captain Planet is inspired by the DC Comics character (previously Charlton character) Captain Atom. Other aspects of the show (five teenagers with powers summoning a super-being of greater force, looks and personality bits of the teenagers) are inspired on the Marvel Comics "Psi-Force" series.
