Zeus: that one guy you hate because he thinks he's just the best at this sport and he won't stop flirting with girls and it's destroying your yaoi ship
Hades: acts very gay then pulls in his sports jacket and deadpans 'i better hurry home to my girlfriend.'
Poseidon: litterally Haru from free except with more emotion.
Persephone: secretly shipping everyone, has to do way too much shit to prove she's 'worthy' of Hades, and weeaboos still hate her unreasonably
Hera: that one yandere
Hermes: has to be litterally paid to join sports team
Dionysus: joins team litterally for the purpose of looking at semi-clothed men, even though he is the most unatheletic person ever.
Hephaetus: disabled but joins team anyway. Has an adorable character arc where he manages to partially overcome his paralyzation or finds a way to compete in said sport without overcoming anything.
