Hubris, or deadly pride, is Annabeth's fatal flaw. Annabeth thinks that she is able to do anything: get her parents back together, build great monuments, and save Luke, as shown in the second book. She sometimes even thinks she can rebuild the world into an even better place than the immortals did. She also has a deep fear of spiders, (arachnophobia), due to the contest between Athena and Arachne.
