Batman inspired several imitators over the years and centuries after their debut. Such as Bron Wayn the Batman of 30th century Earth-One, and Brane Taylor the Batman of 30th century Earth-Two who with their future Gotham Cities safe as had their ancestors a thousand years previous. And they had legacies that went back even early, with Batman the sixth and the fifteenth paving the way for Bron as had the original Brane and Ricky in decades before Taylor arrived on the scene.
Then there was the costumed crusader of the planet Zur-En-Arrh. Known by his civilian identity of Tiano, his one adventure with the Dark Knight revealed that inhabitants of Earth-One have Kryptonian-level powers on his world. As for Tiano and his cosmic twin, the third future Batman of Earth-Two, not much was revealed about him save that he preserved alive his predecessors. Both Batmen had advanced technology that enabled them to get a notch up on the criminal element, although it was left to the heroic dispositions of the original Dark Knights to set the standard by which they and still other undocumented Gotham Gladiators would follow.
Tiano and his doppleganger appeared but once, yet manifested the self-same conviction as had Bruce Wayne from the 20th century.
