14. Clan of the Cave Batman
And now let’s talk about that time Batman was a caveman.
The story in question comes from Batman: The Return of Bruce Wayne, a mini-series follow-up  to Final Crisis. After Wayne was struck by the Omega Sanction and presumed dead, he was actually thrown back in time, on a quest to get back to the present.
His first stop was in caveman times, where he was welcomed as a hostile visitor who didn’t speak the common language. When the leading big strong caveman attacked Bruce and tied him down to a mountain top, he was saved when a young human Bruce had saved appeared with Batman’s utility belt and a cowl/cape made out of a huge prehistoric bat.
So Bruce Wayne became Batman once again. He defeated his enemy before going over a waterfall and being skipped forward to the era of the Pilgrims. But that’s a story for another time.
