Blonde, Brunette, Redhead: Aphrodite is the Blonde, Athena and Artemis are Brunettes and Persephone is the Redhead.
Nice Job Breaking It, Hero: All girls have their moments: Athena accidentally sends a storm of inventions down to Earth, Persephone runs away from home after a fight with her mother and friends, Artemis breaks the Hero-ology statue and Aphrodite starts freaking war! Pheme notes three of them in Pheme the Gossip.
Athena
Aphrodite
Clingy Jealous Girl: When it seems Athena has attracted the attention of Ares.
Reluctant Fanservice Girl: Aphrodite is annoyed at the constant attention in Aphrodite the Beauty so she tries to transfer the attention to Athena by giving her a makeover.
Persephone
All Girls Want Bad Boys: Somewhat subverted. Despite his reputation and looks, Hades is actually one of MOA’s kindest god boys.
Masculine Girl, Feminine Boy: She’s badass and loves sports. Acteon is kind-hearted, gentle, and never holds a grudge.
Other Goddess Girls
Eris
Pheme
Iris
Clingy Jealous Girl: Mostly subverted. She is a little jealous but absolutely nowhere near clingy. She even tries to help her crush and Anthiea get together because the latter is her best friend.
Genki Girl: One of the perkiest girls in book series.
I Want My Beloved to Be Happy: Is willing to help Antheia and Zephyrus get together in spite of her crush on the latter.
Amphitrite
Hestia
Echo
God Boys
Apollo
Ares
Jerk with a Heart of Gold: Starts off as a bully but Aphrodite eventually brings out his softer side.
Dionysus
Poseidon
Hades
Perky Goth: While not exactly ‘perky’ pe say, he is noticeably less moody than most Goths, especially around Persephone.
