Jim knows him as his old friend Eduardo at the moment, arriving in Gotham at the head of a military task force to lend a hand to Jim in No Man’s Land.
In fact, it appears that Bane is literally dropping in from the skylight of what looks like a church, along with a bunch of fellow soldiers.
Jim calls him “Eduardo,” but fans know that Shane West was cast as Bane, and he appeared in some other trailers and images looking more like the Bane of comics and other adaptations.
