Noal Vereuse is a member of the Space Knights in Tekkaman Blade. He comes from a noble family, and his father, a military officer, pushed him into a military academy. Resisting this path, he left the army and joined Heinrich von Freeman's team in the Outer Space Development Organization, a decision that led his father to disown him. As a member of the Space Knights, Noal serves as the primary pilot of the spaceship Blue Earth, and later becomes a pilot of Sol Tekkaman 2, an Earth-made Tekkaman armor, to assist Tekkaman Blade in the fight against the alien Radam.

Noal is characterized by a confident and fearless demeanor, often carrying a carefree attitude that masks a deep sense of loyalty to his friends and a strong desire to protect Earth. He is initially wary and even hostile toward the mysterious young man who falls from the sky, whom he nicknames D-Boy, short for Dangerous Boy, due to his reckless actions. Over time, however, this suspicion gives way to trust, and Noal becomes one of D-Boy's most reliable and trusted companions, viewing him almost like a brother and often acting as a mentor figure. He is also sensitive and empathetic beneath his tough exterior, forming close bonds with his fellow Space Knights, including commander Heinrich von Freeman, navigator Aki Kirasagi, and the other support members.

Throughout the story, Noal plays a key role as both a pilot and a fighter, supporting the team from the Blue Earth and later directly in combat as a Sol Tekkaman. His development sees him grow from a soldier with a troubled family background into a dedicated protector willing to risk everything for his comrades. In the later stages of the war against the Radam, he is killed in battle while trying to save Takaya Aiba, the man behind Tekkaman Blade. His notable abilities lie in his piloting skills, his courage in battle, and his capacity for loyalty and sacrifice.
