Adonis is a superhero and member of the Liberty League.
Also appropriately for his codename, Adonis has some sort of psychic power that, when focused on a woman, makes her extremely attracted to him and willing to do anything to win his approval. It's not a permanent effect, though.
It hasn't been shown if his power is able to affect girls before the onset of puberty, or how it affects homosexuals in general.
Adonis has a very sexist attitude towards women, which leads the ones who actually know him to dislike him. He's known for using his naturally attractive appearance (and even, possibly, his psychic power) to seduce women.
He is cocky and dismissive of the actual potential threat of attackers.
He considers himself a connoisseur of hard alcohol, and insists on keeping a fully stocked liquor cabinet on Liberty Island.
