Seleukos is Adonis's friendly rival. If you got tired of looking at Adonis's golden penis, then take a gander at Seleukos's shield! Triple breasts!
This Anatolian-born (from Ephesus) soldier of Thracian lineage has a reputation of being a person of a very pragmatic and stubborn nature, as opposed to Adonis's chivalric values. Seleukos, like Adonis, is also very vain.
He dedicates himself to the goddess Artemis (the many-breasted) and is an accomplished javelin thrower.
