Rip Hunter is one of the supporting protagonists in Batman: The Brave and the Bold.
He is voiced by Brian Bloom.
As the world's most renowned researcher in the field of time, Rip Hunter invented several devices that allow him to travel across time and space. He soon became a time traveling hero and took the name "Rip Hunter" so that none of his enemies could travel into the past and assassinate him. Over time, he was famously known as the Time Master. In the 21st century, he joined the Justice League International as a reserve member.
Rip Hunter detected Batman's erasure from the space-time continuum and brought the news to the JLI. He traced the event to the actions of a mysterious group of assassins, the Batman Revenge Squad, and initiated a mission across time to save the remaining Batmen. Hunter piloted his Time Sphere and deposited two heroes in each time period with a homing device which would take them back to the Sphere when activated. When the mission failed to save Batman, Rip Hunter and Martian Manhunter realized the answer lay in the future. Equinox revealed himself to still be alive and the source of Batman's disappearance. Once defeated, Batman resurfaced and Rip Hunter brought him to the future to reunite with the JLI and meet four other Batmen.
