Kreon's hybris causes him to attempt to violate the laws of order or human rights, another main part of a tragic hero Antigone might be the name of the tragedy, but I believe that Creon is the winning candidate.
Examining the factors that create a Greek Tragedy, and a tragic character, it is clear that the tragic hero is in fact Creon.
The argument that Antigone is the hero is deffinatly a strong one. A tragic hero is a character who is known for being dignified and has a flaw that assists to his or her downfall.
Many hold that it must be Antigone, herself; after all, the play does bear her name. In Antigone there are two main characters; Creon, the tyrant king of Thebes, and Antigone, the daughter of Oedipus and Jocasta She wants to bury her brother Polyneices even though this would be going against Creon, who is her uncle and the king.
