In many Malvinas' War tales, monster apparitions like inhuman beasts, ghosts, zombies, exhausted bodies, etc, are frequent. Commonly they are told in a grotesque way, it means in a mix of comic and tragic but mainly tragic way. So the grotesque becomes in sinister. Even though in a former sight the monsters are characterized by their difference, according to the Freudian conception the sinister is produced because of the coming back of something familiar that became strange in the repression process. Into this frame, in this paper we intend to analize some Malvinas' War tales in order to understand what becomes familiar --and then terrifying-- their monsters. [ABSTRACT FROM AUTHOR]
