The character development in "Saint Seiya" is another key element that contributes to its enduring popularity. The protagonists are multidimensional, with complex personalities and backstories that make them relatable and human. Their struggles, both physical and emotional, serve as a reminder that even the strongest individuals can be vulnerable. The character of Shun, for instance, grapples with his own darkness and the trauma of his past, making his journey towards redemption all the more poignant.
