"Electra is one of the most popular mythological characters in tragedies. She is the main character in two Greek tragedies, Electra by Sophocles and Electra by Euripides. She is also the central figure in plays by Aeschylus, Alfieri, Voltaire, Hofmannsthal, and Eugene O'Neill. Her characteristic can be stated as a vengeful soul in The Libation Bearers, the second play of Aeschylus' Oresteia trilogy, because she plans out an attack with her brother to kill their mother, Clytemnestra. - Wikipedia"
