Jerl was the name of a Tirolian on Tirol who was one of the many natural-born citizens left behind by the Robotech Masters. When the Invid sent down a series of Inorganics to begin attacking those on the planet and to search for the Protoculture they believed to be there, Jerl and another Tirolian named Seb watched them from afar. Seb conceived of a plan for Jerl to fire his missile launcher at a series of rocks, causing an avalanche to fall over the Invid robots — a plan which seemed to work. The pair then found themselves surrounded by Invid Hellcats, which attacked, killing Jerl. Seb survived, reaching the ground, but will be killed by the Inorganics: who had survived the rock avalanche. (Robotech II: The Sentinels: "The Inorganics")
Behind the Scenes[]
In the episode, the fate of Seb and Jerl is left clear but unseen. In the comic, however, it is clearly stated and shown that the pair are killed. The script for the episode, released in Robotech II: The Sentinels Script Book Volume 1, notes that the two should be twins, an idea apparently missed in production. The pair also look entirely different in their comic appearance, Seb losing his black hair and mustache for apparent blonde-curls and Jerl losing much of his defining chin.
