Rosward

Saint Roswald is one of the World Nobles, whom is allowed to reside in the Holy city of Mariejois.

Personality
Roswald is noted to be the most-responsible of his family yet seen; as seen when he scolded his children for their behavior. Though he scolds his children, he deeply cares for them and has "never hit his son", despite his behaviour and showed deep anger at Luffy for hitting Charloss. Like his daughter Shalulia, he has deep pride in his ancestry. Of his family yet seen, he is the only one who hasn't been seen abusing anyone, citizen or slave, though he apparently has a collection of Pirate Captins, and does nothing to stop or alter the treatment that his children give others.

He also seemed to be unaware of the situation at hand when the pirates reacted at the Auction House. While he acted fearlessly, he seemed incapable of thinking that he might actually be defeated, acting as if he was untouchable.

Abilities and Powers
He has the power to summon an Admiral of the Marines as well as the authourities and power linked to him being a World Noble. He also wields a gun, but when seen using it shoot almost aimlessly. He had no fighting skills and was taken out in one hit.

History
He is first seen with his daughter, Saint Shalulia, looking down on his runaway-blown up slave, Dias, who was the Captain of the Acumate Pirates. After his dog urinates on the man, his daughter shoots him with a gun, displaying no remorse afterwards. A demon-like creature is seen behind him. Later in the story, it is revealed that the demon-like creature is in fact, Pirate Captain Jean Bart.

He is then seen at the Human Auctioning House, with his son Saint Charloss and daughter Saint Shalulia. He becomes displeased with his son, Charloss for bidding 500,000,000 on Keimi.

When his son was attacked by Luffy, he used his cane (which is a concealed rifle) and started shooting randomly around Luffy, then shouted out for someone to call for an Admiral. Sanji kicks the cane out of hand, followed by Usopp knocking him unconscious, after accidentally falling down from the rooftop and smashing his face into the floor". He was seen later seen knocked out and unconscious together with his son when Shalulia scolded the marines for being unable to capture the Straw Hat Pirates.

Trivia

 * He is noted for having a "Pirate Captain collection".
 * According to his daughter Shalulia, he has never beaten his own son Charloss, something that the Straw Hats did in their first day on the island. His wife(s) have yet to be seen.
 * When Hancock speaks of her past, she identifies a man who was "the very vision of terror itself". The man's silhouette shows a hair-style that matches Roswald's family, however the only person in his family that matches the silhouette exactly is Roswald himself.
