Clawface

Clawface was the most loyal servant to Brokenstar and the secondary antagonist of Into the Wild alongside Brokenstar's deputy Blackfoot ( later Blackstar), but Blackfoot wasn't evil; essentially naieve. Altough Blackfoot was the deputy to Brokenstar; Blackfoot was not smart and a coward. Clawface was smart and totally dark; so he was the second-in-command of the ShadowClan. He killed Firestar's girlfriend, the female medicinecat Spottedleaf and stole many young cats  for Brokenstar. Clawface was a minor villain in the Omen of Stars and also a henchman of Tigerstar, the best friend of Brokenstar. Clawface is the tertiary antagonist in my own serie Moonrise, alongside Thistleclaw and Mapleshade, serving as a high-ranking-member to Darkstar ( warning: own mind-villain), Leopardheart and Scourge.
