The following are some characteristics which you might have mentioned in your summary:

1.  An unusual or miraculous birth.  Frequently as the child of a god or goddess and a mortal.  The stories of Heracles (able to kill serpents in his crib) or Perseus, born of Danae and Zeus (in a shower of gold) come to mind here.

2.  The patronage of a god:  Hermes, Athena the most likely.  Aphrodite sometimes.  Achilles, of course, has his mother Thetis.

3.  The hatred or enmity of a god (Nemesis).  Heracles and Hera,  Odysseus and Poseidon etc.

4.  An adventure (or more than one) frequently involving a journey of some kind.

5.  One or more monsters to be overcome.

6.  A trip to the Underworld-the ultimate monster-Death.

7.  A male side-kick-Theseus and Pirithous,  Heracles and Iolaus, Jason and the Argonauts etc.

8.  Superior qualities: strength, intelligence, good looks.

9.  Temptation from a dangerous woman.

10.  Some character weakness, lust or lapse of judgment.
