Jacinda Rodríguez is the daughter of the original Delvadian revolutionary-turned-mercenary known as the Tarantula. At some point after his death, she inherited his costume and identity.

Jacinda's first assignment as a mercenary came from Higashi of the Four Winds. She was partnered with Marie Batroc and tasked to kill Agent X, Outlaw and Taskmaster. The two women waited on a rooftop for the three as they fought off mercenaries below. Taskmaster made it to the roof and caused them to fall over the side. He shot them both for good measure. Writer Gail Simone later confirmed that both characters survived their encounter with Taskmaster.

Later, as the Tarantula, Jacinda appeared as the partner of the Devil-Spider, who was actually Roderick Kingsley, the original Hobgoblin. Her whereabouts since Kingsley abandoned that identity are unknown.
