Defenders of the Earth (1986) : 1x38

Rick Gordon's new friend at Central City High ! Carlotta Vallejo- requires his help when Ming backs revolutionary forces to dethrone her father from the Presidency of the tropical island of Esmerelda. While Ming gathers all the blue orchid flowers on the island for use turning the world's population into Frost People, Rick and Carlotta fly to Esmerelda and search for her father, but are captured by El Jefe, the mercenary leader of the upsurge. Back at Monitor Dynak X informs the Defenders that the temperature of the island is being unnaturally lowered, posing potential weather problems and prompting the heroes- sans Mandrake and Lothar- to board the Terry and set out to investigate. Rick and Carlotta escape from El Jefe, discover that Ming has diverted irrigation waters to build a huge glacier, and locate the President. To their horror, they find he has been turned into a Man of Frost before they are once again captured. The Defenders arrive and walk right into a trap, however Mandrake and Lothar, who arrived later disguised as a Man of Frost and an Ice Robot, spring them from Ming's dungeon. They invade El Jefe's jungle mercenary camp and rescue Rick, Carlotta and her father- who by now is returning to normal because the Frost Serum only works for two days. Furious, Ming blows up his glacier, causing a raging avalanche, which Rick subsides by employing a solar mirror to direct the sun's rays to melt the ice and divert it underground destroying the Ice Caves and all of Ming's blue orchid Frost Serum.
