After graduating and becoming an adult, Tim secretly spent his time as a covert mercenary, trained by Katana and other mentors under the name Jace before returning to Gotham, where tensions between himself and his family continues.

As Batman, Jace Fox differs from the original in his more restrained approach to crime-fighting and how his identity as an African-American influences his outlook and perception as a vigilante.

In 2020, the character would be reinterpreted under the name "Jace Fox" and was provided with a new origin during the Infinite Frontier initiative, appearing as the new Batman incarnation as part of the Future State event.

The character's status quo being in New York City was announced shortly after, slated to take place in the sixth issue of the series.

Ridley also added that he intended for Jace's origin and approach to be different from one another, whereas while Batman operates using fear in part of making villains feel the same kind of fear he had when witnessing his parents' death, Jace was the individual who caused rifts in his family due to evading responsibility thanks to his father's wealth and influence within the criminal justice system and seeks to both own up to it ultimately and inspire others (including African Americans) to do the right thing rather than wait for the criminal justice system to address moral failings.

[6] Later on, Tim fell in with the criminal group, The Terrible Trio, taking on the identity of The Vulture and attempting to rob guests of Bruce Wayne's penthouse, but was subdued and captured by Batman.

[8] In his rebooted origin, Tim, due to his family's immense wealth, became a hedonistic playboy, indulging in a jet set life of non-stop partying and promiscuous affairs.

[9] After a decade abroad being trained by multiple teachers, including that of Katana, Timothy, now going by his nom de guerre of "Jace", returned home as his father inherited the Wayne Family's fortune.

[2] Jace officially takes up the mantle of Batman,[10] choosing to appropriate the Dark Knight's identity under the notion that his father and Bruce Wayne were corrupt.

However, Tiffany Fox had recently donned her own vigilante outfit, seeking to help a friend, and briefly fought with members of Strike Force Bat.

Batman successfully altered the machine, using it to defeat Pariah, and then joined the other heroes in the final battle, along with the returned Justice League.

After a period of turmoil involving his biological mother Elena Aiko being kidnapped, and the circumstances of Jace's birth coming to light, the Fox Family was fractured.

[19] Similar to Batman and other human crime-fighters in Gotham, Fox possess no inherent superpowers but is skilled in hand-to-hand combat due to both his military training and mentorship under Katana.

Jace also demonstrated a strong will from enduring experiences in a Markovian secret prison and Sinestro's yellow power ring, a trait credited to making him worthy of the Batman mantle.
