Cyrus Broderick is the last of the four leaders of the Quadrant after Ricardo Diaz took over most of the organization after killing the other leaders.


Cyrus Broderick attended a meeting of the Quadrant at Villa Centanni. He watched on as Ricardo Diaz killed Remy Cartier for a spot amongst them, before he gave a business proposal.[1]

Having killed Lydia Cassamento, Diaz summoned Broderick and Dragos Ibanescu to Star City Police Department, killing Ibanescu when he wouldn't give his loyalty to Diaz's cause. Frightened by this, Broderick gave the Quadrant's loyalty.[2]

He was arrested when John Diggle, Wild Dog, Samanda Watson, and the FBI raided Diaz's base of operations.[3]

However, 5 months later, Broderick was back out and helping Diaz in his schemes.[4]
