Describe the key characteristics of at least two secondary characters from oedipus the king.

Polynices - Son of Oedipus, and also his brother. Polynices appears only very briefly in Oedipus at Colonus. He arrives at Colonus seeking his father’s blessing in his battle with his brother, Eteocles, for power in Thebes. Polynices tries to point out the similarity between his own situation and that of Oedipus, but his words seem opportunistic rather than filial, a fact that Oedipus points out.

Haemon - Creon’s son, who appears only in Antigone. Haemon is engaged to marry Antigone. Moved by his love for her, he argues with Creon about the latter’s decision to punish her.
