Within the narrative, Veldora is one of the most powerful dragons in existence, a being of immense magical energy and intellect. He is known as the Storm Dragon, a title reflecting his mastery over wind and storms. Initially, Veldora is sealed within the Cave of Isolation by a hero, a state from which the protagonist, Rimuru Tempest, eventually frees him.

Upon his release, Veldora becomes a crucial ally and friend to Rimuru. He offers guidance, protection, and often serves as a source of comic relief due to his somewhat dramatic and boisterous personality. Veldora possesses a vast knowledge of the world and its history, having existed for millennia. His abilities include devastating storms, dragon breath attacks, and the manipulation of spatial magic. He eventually takes on a human-like form, which aids him in interacting with the inhabitants of Tempest, Rimuru's burgeoning monster nation. His presence significantly bolsters the strength and influence of Tempest, making him a key figure in the series' overarching plot.
