Racine portrays Nero's true nature as revealed by his sudden desire for Britannicus's fiancée Junia. He wrests himself free from his mother's domination and plots to assassinate his adoptive brother. Nero is driven less by fear of being overthrown by Britannicus than by competition in love. His desire for Junia manifests itself in sadism towards the young woman and all that she loves. Agrippina is portrayed as a possessive mother who will not accept the loss of control over both her son and the Empire. Despite giving his name to the play, the character of Britannicus is more minor than those of Agrippina and Nero.
