Saul is a giant, though not from Elbaf—he was born elsewhere. He rose through the Marine ranks to become a Vice Admiral, and during his time in the Grand Line, he crossed paths with numerous Devil Fruit users, though details of those encounters remain sparse.
Personality-wise, Saul embodies the gentle giant archetype: loyal but not blindly so. He questioned orders at least twice when they clashed with his personal code of "Moral Justice," refusing to simply follow the Marines' "Absolute Justice" doctrine. His most distinctive trait is probably his distinctive, somewhat awkward laugh ("Dereshishishishi") that he's a bit self-conscious about. Despite this, he genuinely enjoyed making others laugh and was always encouraging Robin to embrace humor.
Saul became one of the three most influential figures in Nico Robin's life. He wore a cowboy hat that Robin would later adopt herself, and his philosophy about laughing—even when it hurts—shaped how she'd respond to pain and danger with a smile. More importantly, his middle name connected him to the Will of D, knowledge he passed on to Robin, who eventually shared it with Luffy.
His friendship with Vice Admiral Kuzan (later Admiral Aokiji) ran deep; they both valued Moral Justice over blind obedience. When Kuzan ultimately chose to let Robin live, it was largely as a final gesture to Saul.
