Frodo Baggins
Battle helmets are commonly used by virtually all races in Tolkien's writings. The Rohirrim were partly modelled on the Anglo-Saxons, who wore elaborate helmets; Éomer's helmet had a long white horse-tail. The Crown of Gondor was a jewelled battle-helmet; Aragorn received it at his coronation. Frodo Baggins and Sam Gamgee use Orc-helmets as part of their disguise in Mordor.
