Raze, although his given name was Koro, was born in an unknown place in East Africa during the 14th century. In the year 1373, when he was in his mid 30's, he was called upon to defend the land from European Lycans and Vampires when the war spilled from Europe into Africa. During a battle Raze was turned into a Lycan by Lucian who was impressed with his battle prowess and thus shunned by his tribe. He then joined Lucian and the Lycans in the cause to defeat the vampires.
Centuries later, he was in charge of apprehending the human descendant of Alexander Corvinus, Michael Corvin. In a particular incident, Death Dealers were following him and fellow Lycan Trix. As Raze was following Michael, he sensed the vampires nearby and a shoot-out broke loose in the subway between the Death Dealers and them, allowing Michael to get away. He was scolded by Lucian for letting Michael escape, but due to his loyalty and age as a Lycan, Lucian did not punish him. Later, when Amelia and her entourage arrived, the Lycans, lead by Raze, slaughtered the council. He bled her dry, under the orders of Lucian to fulfill the plans of creating a lycan-vampire hybrid. Upon reaching the Lycan lair underground, he found Lucian dead. Angered at Lucian's death, he got revenge by confronting Soren and killing him. He later was approached by Viktor and the Vampire Elder wrestled Raze to the ground with his bare hands and plunged his sword in the Lycan's chest, killing him.
