In his old age, Batman used proxies to fight crime. He himself stayed mostly confined to the Batcave. He headed the Silent Cavalry as a counterpart to Superman's Justice League. He opposed the imprisonment of rogue metahumans in the Gulag. The Silent Cavalry pretended to ally themselves with Lex Luthor's Mankind Liberation Front so that Bruce could discover Lex's plans. Once they discovered that Luthor was brainwashing Captain Marvel, they captured the MLF members.
Batman survived the United Nations attack on the superheroes. After these events, Bruce turned his home into a hospital for the survivors of the bomb and used Luthor's Mankind Liberation Front members as hospital staff.
After the metahumans formed their own community, he remained actively involved in working with and training the younger heroes. Bruce eventually became the godfather to at least one of the children of Superman and Wonder Woman and eventually died of old age.
