His hatred of pirates is one of his key personalities. He hated them even as a child, and when he was a solider. During the marines, he was called a 'torturer' for how he treated pirates. He hates pirates so much, he considers them the closest things to 'evil'. He has even prepared 2,000 marines to go after One pirate when he escaped his cell, and he did not even think it was a little overreacting.
Brog was a child, who despised pirates. When his country was invaded by pirates, he joined the military to drive them away, becoming famous. When his country joined the New world government, he became a marine to defeat pirates.
He later married a women, and had a child. She died, soon afterward.

He is seen carrying a sword, which he was able to use to defeat the Reck, and the rest of the crew with ease. He has been able to run 100/m per hour, and this was not even his full speed. He could also crush steel with his full speed. He also know's multiple techniques in Rokushiki, knowing both Rankyaku which can harm Tack, and Tekkai which can stop him. He won against an extremely powerful pirate, and a Zoan user as well. While losing to The leader of that pirate, he put up a good fight, and only lost to the chance his son was alive.
