The Odysseus starts out full of himself. He wants everyone to respect him. This sets up the theme of courageous.
Odysseus saw that it wasn't that easy to attack anyone. He saw that the Cyclope is much stronger when he ate his men. Odysseus made a clever plan to trick the cyclope to get out. He made the cyclope drunk and stabbed his eye, then stole his sheep. This event was very vicious.
Odysseus changes by accepting he's not strong but although he is very clever. By knowing this, he bragged about it to the angry cyclope. He changed by thinking he's very powerful but at the end he realized he was smart.
