Hector Ayala was born in the city of
San Juan, Puerto Rico. He was attending college at Empire State University in New York City, when he found the tiger amulets that the
Sons of the Tiger had worn and discarded. By putting on all three amulets, he was transformed into a superhuman form called the White Tiger. He discovered that wearing all the pendants at once increased his strength and gave him nearly superhuman skill in the martial arts. In his alter-ego, Ayala went into action for the first time against a street gang. He then battled the
Prowler, who believed him to be a murderer. The White Tiger battled the
Jack of Hearts who also believed him to be behind his father's murder. The White Tiger fought off unnamed costumed assailants of the
Corporation crime cartel, who were threatening his sister and Jack of Hearts. Alongside Jack of Hearts,
Shang-Chi, and
Iron Fist, the White Tiger fought Stryke and other agents of the Corporation, and learned his brother Filippo was attempting to find employment with
Fu Manchu. Hector then encountered the Sons of the Tiger. Ayala was impersonated by Professor Vasquez, and battled
Spider-Man in the confusion. Ayala's secret identity was later publicly exposed in a battle with the
Lightmaster at
Empire State University grounds. Alongside Spider-Man and
Daredevil, he then battled the
Masked Marauder,
Darter, and
Carrion. Ayala was later gunned down by
Gideon Mace and nearly killed. He was operated upon to remove the bullets, and recovered. Having gained an unhealthy psychological and physical addiction to the tiger amulets, Hector abandoned his identity as the White Tiger. He gave the amulets to a private detective nicknamed Blackbyrd, who returned them to the Sons of the Tiger. Hector then moved out west with his girlfriend Holly Gillis. After a while, the call to don the amulets and fight evil became too strong and Hector once again became the White Tiger. Soon after, Hector was wrongly accused of murder and convicted despite the efforts of his lawyer, Matt Murdock (a.k.a. Daredevil). Ayala was shot dead trying to escape, shortly before evidence emerged that proved his innocence.
Family legacy Angela Del Toro, Hector's niece and an FBI agent, inherited the Jade Tiger amulets. Angela quit the FBI to understand the amulets, and was trained in the use of their powers by Daredevil, becoming the latest person to assume the White Tiger identity before being killed by the Hand and resurrected as their servant. Having been healed by
Black Tarantula, she joined
Daredevil in the
Hand after he takes over and attempts to reform the organization. However, Angela is still corrupted by the Hand's influence and after Daredevil's attempts fail, she is incarcerated for her crimes. Hector's teenage sister
Ava Ayala inherited the amulets and appeared as the new White Tiger. Angela is later freed by the
Maker and given an alternate version of the White Tiger amulets from another universe. Angela and Ava are pitted against each other until both sets of amulets are destroyed, freeing Angela from her corruption but depowers both of them.
D'Spayre invades the Tiger God's realm and possesses Hector's ghost. Through Hector, D'Spayre manipulates Ava into summoning him and giving him a corporeal form. When Ava is nearly overwhelmed, the freed Hector and Tiger God appear before her in a vision and the Tiger God makes Ava his permanent host, repowering the White Tiger amulets and merging them with Ava's body, empowering her enough to destroy D'Spayre. Ava and Angela would later be guided by a dream of Hector into reconciling with each other. ==Powers and abilities==
