Thomas Elliot or Hush would be the perfect foil for Bruce Wayne in The Batman — Part II. While the last movie was a detective movie showcasing Batman's detective skills with Riddler being the antagonist using puzzles, it neglected Batman's other side being Bruce Wayne. And, in the comics, Hush mimics Bruce Wayne and character assassinates him. Also, it is mentioned that Bruce has ignored this part of his life, with others saying no one has seen Bruce in ages, so if Hush came and took over his life, no one will likely realize he's acting differently.
