Thomas Wayne

Thomas Wayne (b. 1942) (d. June 26th, 1981) was the son of Patrick Wayne, the grandson of Alan Wayne, the husband of Martha (née Kane) Wayne, the brother-in-law of Jacob and Gabrielle Kane, the father of Bruce Wayne, the father-in-law of Tony Stark, and the grandfather of his son's children. An alpha, he was a doctor and respectable man, and had employed Alfred Pennyworth. After his and his wife's death, it was Alfred who raised their son. It was also his and Martha's death that led Bruce to becoming a vigilante. Through his son's name, he is also indirectly one of the namesakes of his grandson, Edward Wayne.
He, like his wife and niece Kate, makes a brief appearance in the little man who wasn't there.
