Heavy Metal L-Gaim (重戦機(ヘビーメタル)エルガイム, Jūsenki (Hebī Metaru) Erugaimu, literally "Heavy Fighting Machine L-Gaim") is a mecha anime television series, begun in 1984, which was directed by Yoshiyuki Tomino. Its characters and mecha were designed by Mamoru Nagano, who would later go on to create The Five Star Stories. Heavy Metal L-Gaim takes place in the Pentagona System, a solar system made up of five planets. Oldna Poseidal, the legendary emperor from the planet Gastogal leads his 24 Temple Knights from planet to planet until all have fallen under his control. His final victory is on the planet Mizum in 3975 when he defeats Kamon Walha V, ruler of the Yaman Clan. Kamon hides his heir, Kamon Myroad on the planet Mizum with the legendary white mecha, L-Gaim. Fifteen years later, now grown up and known as Daba Myroad, he leads a rebellion to free the planets of Pentagona from Poseidal's grasp.
Heavy Metal L-Gaim begins in the wastelands of the planet Koam. Daba Myroad, traveling with his friend Mirao Kyao encounters a group of thieves led by Miyama Lilin, who seeks to sell the L-Gaim for a lot of money. The thieves' initial attack ends in failure and one of them, a teenage girl named Fanneria Amu defects after falling in love with Daba. When Daba makes a promise to one of the dying thieves to deliver a cash card to a man named Amandara Kamandara, the three of them head to the city of Prearmo, where the thieves continue to chase them. It is here where Daba meets Lillith Fuau, the last remaining fairy in the Pentagona world. Lilin is eventually killed by one of her own subordinates, and Gavlet Gablae, a man who seeks to join the Poseidal military becomes their new leader. While Daba and the others have a hard time finding Amandara Kamandara, Gavlet finds him himself and gets a recommendation to join the Poseidal military, where he's placed under Chai Char, one of the military's 'Elite 13'.
