Which character is the best example of tragic flaw

Achilles who had both literal and figurative fatal flaws.

Explanation:

The legendary hero of Greek mythology was an almost invulnerable warrior with one widely known fatal flaw: the heel that his mother held him by when she dipped him into the river Styx to make him strong became the weakest part of his body. Ultimately, once discovered by the enemy, the heel ended up being his undoing. Today an "Achilles' heel" refers to anyone's fatal flaw.

Another flaw was his pride. Not only is Achilles upset because he was fond of Briseis, he is also upset because his pride took a hit in front of all the warriors who saw that Agamemnon got the better of him.
