White Tiger is the identity used by several fictional characters appearing in American comic books published by Marvel Comics.

The first White Tiger (Hector Ayala) was created by writer Bill Mantlo and artist George Pérez in the black and white Marvel magazine, Deadly Hands of Kung Fu in the early 1970s. Hector Ayala was born in San Juan, Puerto Rico. He could transform into the superhuman White Tiger through the power of the Jade Tiger amulets.

In his alter-ego, Ayala fought foes such as the Corporation crime cartel and teamed with heroes including Daredevil and Spider-Man. After many years of fighting crime and nearly being killed, having his secret identity publicly exposed by the villainous Lightmaster and becoming psychologically and physically addicted to the tiger amulets, Ayala retired.

But 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 (Daredevil). Ayala was shot and killed trying to escape, shortly before evidence emerged that belatedly proved his innocence.
