Ruby and Socks

Ruby and Socks were the main antagonists in the Rise of Scourge and both the littermates of the evil leader and founder of the BloodClan, Scourge ( born as Tiny). Ruby was a grey she-cat and the older sister of Scourge, and Socks was a black with white tomcat. Later, Scourge, his personal right-hand Bone and the best enforcer to Scourge, Brick, killed this partners in crime.

They teased Scourge; the reason Scourge became evil and a murderous psychopath and become a friend of Bone and Brick, and thus the leader of the BloodClan.
