It's been a while since I last viewed the animation. The name of the main character is a bit unclear, but it's either Nazire or Nasir. He hails from a royal background and was destined to meet his demise through a thunderstorm at a specific age due to being wrongly perceived as evil instead of the inherently good person he was supposed to be.
There's an opposing character, somewhat of a nemesis, who is always dressed in white. Eventually, they become friends to combat evil together. This opposing character's parents are dragons who are imprisoned in a location resembling hell, and they urge the white-clad character to eliminate Nazire, claiming that he took their place. However, the white-clad character, driven by their inherent goodness, consistently questions their dragon parents about why they want Nazire dead.
Everyone, including Nazire's parents, is aware of his extraordinary powers, and out of fear that he might inadvertently harm others, they kept him isolated from the rest of society.
