A man born with super human strength that can resist even bullets, similar to Kenshiro of Hokuto no Ken. He also heals much faster than a normal human. He was separated from his younger brother Nachi since childhood and was adopted by the Saiga family. He has a scar in the shape of the Star of David on his right hand which is the source of his great strength and skill. This scar is also a sign that he's destined to overthrow his real father. Riki's mother was executed for poisoning 13 infants, and Riki and his brother Nachi escaped prison before they were dealt with punishment. ZhÄ�ng Shàn-GuÇ� stopped Riki from committing suicide infront of his mothers grave and became Riki's sifu in the ways of Qi Gong. Riki's Girlfriend/Childhood friend was driven to death by Yakuza (although the Yakuza only caused her to quickly commit suicide after being kidnapped). This lead Riki to murder the Yakuza which sent Riki to jail. He keeps the 5 bullets that the Yakuza shot him with in his chest as "souvenirs". After Riki escapes jail he searches for his brother Nachi.
He owns the Rumba bar where Pepê Lima works and he is the leader of the Favela gang.
Height: 212 cm Weight: 130 kg True Identity: Alexander the Great/Iskandar, King of Conquerors Master: Waver Velvet Catalyst: Mantle once worn by Iskandar himself Holy Grail War No.: 4th Holy Grail War Rider was originally meant to be summoned by Lord Kayneth El-Melloi Archibald, but due to some circumstances, he ended up being Waver Velvet's servant. Iskandar, or how he refers to himself, the King of Conquerors is a noble and courageous man, who prefers to conquer his enemies by winning without killing and controlling without humiliating them. He is known as a marvelous ruler who once almost conquered the whole known world. He is not pragmatic, but is a person who lets history run its course and acts according to his impulses. While he is wild and somewhat inconsiderate to others, his greed ultimately resulted in the happiness of the people he ruled over. In the new era, Rider is mostly amazed by ordinary modern things, and usually spends his free time exploring modern war vehicles and machinery.
