Alfred Pennyworth is Bruce Wayne's butler, mentor, and father figure. Following the death of Bruce's parents, he became his primary emotional support and the anchor of Wayne Manor's stability.

Over time, Alfred extends this care to the entire Batfamily, serving as the team's moral and emotional anchor, often being the only voice capable of reminding them what it means to be a family beyond combat in Gotham.
