Throughout the Harry Potter series, many characters are either introduced as Aurors or shown to have the potential to battle some of the most dangerous wizards and witches of the Wizarding World. As a result, many Aurors were strong, talented, and accomplished.
Far less flashy than his fellow Aurors, Kingsley stood out for his high skill levels in all branches of practical magic like dueling, Charms, and Defense Against the Dark Arts. As a Ministry official, he was often sent on sensitive missions like apprehending Dumbledore and serving as the Muggle Prime Minister's bodyguard.
Because he was the strongest Auror, Kingsley had many responsibilities. As a key member of the Order of the Phoenix, Kingsley was tasked with protecting Harry and investigating the Ministry's corruption from the inside. After participating in the Battle of Hogwarts, Kingsley was elected as Minister for Magic, a role he excelled in until Hermione took over in the late 2010s.
