how old is bruce wayne when he becomes batman
Bruce is 12. He becomes Batman when he's 25, 13 years down the road. He meets 12-year-old Dick Grayson when he's 27, 15 years away. Barbara Gordon is a year or so older than Robin, and becomes Batgirl when she's 16 and Batman is 30. Batgirl has an older brother, James Gordon Jr, who is two years older than her, making him 18 when Batman is 30, 18 years from now. If we're going by the comic timeline, Barbara should be pregnant with James Jr already.
