Jaguar is the cape name of Oscar Ortiz, the "Spy" of the Suber Up team in Bassetville. He has a day job as a construction worker. When he becomes Jaguar, he can literally turn into a jaguar. He also possesses supernatural senses. He inherited the Jaguar mantle from a previous Jaguar active in the 70s. He originally used his powers to commit crimes for selfish gains, but made a "face turn" after getting busted by his future teammate, La Escarabaja.
In a Neitherworld where Nuevo Gauntlet City is part of Greater Mexico, a version of Oscar works as a taqueria manager and secret angellero, using his jaguar shapeshifting to hunt predatory angels. He was manipulated by Febe T. Dolár into a dueling a feral hellhound-like angel in an underground fight club. Though he proved victorious, he earned the enmity of the fight club's operator towards him and his angellero crew.
