Larn is the main hero in Ralph Bakshi's 1983 animated film, Fire and Ice. He is a young warrior whose village was attacked by a gang of sub-humans from Icepeak.
He was portrayed by Randy Norton, and voiced by William Ostrander.
From their stronghold in Icepeak, the evil Queen Juliana and her son, Nekron, send forth a wave of glaciers, forcing humanity to retreat south towards the equator. Nekron sends a delegation to King Jarol in Firekeep to request his surrender, but this is a ruse orchestrated by Queen Juliana for Nekron’s sub-humans to kidnap Jarol’s barefoot, bikini-clad daughter, Princess Teegra; Queen Juliana feels that Nekron should take a bride to produce an heir.
But Teegra makes an escape and comes upon Larn, a young warrior and the only survivor of a village razed by glaciers, who offers to escort her back to Firekeep. As Teegra is recaptured, Larn teams with the mysterious Darkwolf to save Teegra and then travel to Icepeak to stop Juliana. Darkwolf faces Nekron and kills him as Icepeak succumbs to lava released by King Jarol and is destroyed.
The film finishes with Larn about to kill a beaten sub-human until Teegra stops him saying that "it's over" and embraces him. Darkwolf is seen atop a cliff; he watches the pair, smiles and then disappears. Teegra and Larn kiss at the end of the film.
