Madara Uchiha and Hashirama Senju, both characters from the Naruto series, are renowned for their exceptional speed and combat abilities. However, it's important to note that the Naruto series is a work of fiction, and specific measurements of their physical speed and reaction speed are not provided.
That being said, both Madara and Hashirama are depicted as extraordinarily fast and agile shinobi. They possess superhuman abilities and are known for their swift movements and quick reflexes. They are often shown engaging in high-speed combat, dodging attacks, and launching rapid counterattacks.
Madara Uchiha is particularly famous for his immense speed and agility, which are augmented by his Sharingan and later by the Rinnegan. He is capable of teleportation using his Space-Time Ninjutsu and can move at blinding speeds, making it difficult for his opponents to keep up with him.
Hashirama Senju, on the other hand, is renowned for his immense physical strength and vitality. While specific details about his speed are not provided, he is portrayed as a formidable and agile fighter who can match the swiftness of his opponents.
In the Naruto series, characters' speed and reaction time are often depicted in relative terms, such as being faster than other characters or surpassing previous feats. Unfortunately, there are no concrete measurements or quantifiable data available to provide precise numerical values for their physical speed or reaction speed.
