Making a child of Demeter
So I am kinda creating a son of Demeter for my fanfic universe and basically he like Lityreses would not be the typical nature loving soft kind ty that Demeter kids are stereoyped as usually. Infact the guy is popular at school using his pranks and sometimes blunt sarcasm (cuz he is just ADHD not dyslexic) to make himself popular instead of being an outsider like most main characters. Also he isn't a too keen naturalist.
His fatal flaw is like Thalia aka thirst for power given all his life his father tries to shelter and overprotect him from everything including not letting him take decisions of his own. But the OC like his mother Demeter he subtly values and had a protective spirit for his family.
So I was kinda wondering what would be good first power for him that he subtly manifests from time to time before camp and finding out his demigod lineage. I was thinking maybe mycokinesis: the ability to control fungi and molds or geokineisis.
Edit: Would also like inputs on what first powers to give instead if I turn him into the son of Dinosyus instead while retaining all core parts of his perosnalities?
