Тобіо Тенма

As the son of Dr. Tenma, this character's existence was altered following events involving Astro Boy. Generally portrayed as adventurous, polite, and brave, his personality is defined by a strong curiosity and impatience. However, this very nature proved detrimental, as in certain portrayals, his eagerness led to tragic outcomes, making him less inherently courageous than his robotic counterpart.
