Dalekos is a general in the armies of Atlantis - an elite scion of a family line of barbarian warlords assimilated into broader Atlantean culture back in his grandfather's day when old Vardalek once courted Siren, now the Queen Mother of Atlantis. With his long dark hair, strong nose, and magnetic eyes, Dalekos is a paragon of Atlantean manhood who nonetheless retains a certain exoticism, and indeed he is famous for his romantic prowess among the eligible members of the Atlantean nobility. (He is sometimes called a term that in the rather heteronormative language of Atlantis means 'every woman's man, and every man's woman.')
He's of middle-age but still muscular and well-built, and carefully supervises the regular drilling of new recruits to the royal family's personal guard. Dalekos has a reputation as a hardass and it's a fair one - but he's also beloved by the men and women under his command. You won't see him ask a soldier to do something he wouldn't do himself, and on campaigns he sleeps in the same rough conditions as a newly-minted field officer. He lacks the blessings of Oceanus that many members of the royal family have, but he's strong, fast, and well-armed with orichalcum weapons - and has the somewhat-unusual ability to fly outside of the water, a gift of his family's particular magical heritage.
He is cool but correct with Surfacers and other non-Atlanteans, assuming they are not violating Atlantean sovereignty, about which he admittedly takes an extremely generous attitude. He sees himself as an enforcer of ancient laws and traditions, ones that bring a much-needed civilization to the chaotic world beneath the sea. Everything else is just a distraction. For the monsters that lie beneath the sea alongside Atlantis, he gives no mercy save his trident and hot-blooded wrath - after all, why should he do anything else? They're monsters.
