1.
hero, brave person, valiant warrior
A person of great courage and bravery. In modern usage, strongly associated with the 'hero' character class in Japanese RPGs, anime, and fantasy stories — the chosen protagonist who fights evil.
In modern Japanese, 勇者 is overwhelmingly associated with the hero archetype from RPGs and fantasy fiction — especially the Dragon Quest series, which established the "chosen hero who defeats the demon king" trope. The word has a more elevated, literary feel than 英雄 (hero in a historical or real-world sense).
