Possible PJO crossover Head cannon:
Athena, goddess of wisdom and battle strategy, would be hella taken with our favorite Avenger (Tony Stark, in case there was any doubt in that). So my thoughts are, Peter Parker is Athena's brain-child/gift to Mr. Stark for his purely beautiful mind. It would so fit.
Athena was so taken with our genius, billionaire, playboy, philanthropist that she stayed on Earth with/for him. Enter one B.A.M.F. Virginia Pepper Potts, capable of being an insanely good superhero, but decides to leave the work to the mortals as she focuses on taking care of the greatest mind she's seen since time began.
Is the gifted brain-child.
Are other brain-children that she led him to because they could all benefit from each other and she wasn't about to abandon her poor genius brain-babies to the horrors of the world without some serious backup.
Yep, I have now latched on to the beautiful thought of these three genius children of Tony Stark's are actually Pepper Potts' (aka Athena's).
