Declaring that Alfred is more of a “hero” and less of a superhero doesn’t diminish the character in the slightest.
Ben Affleck’s Batman, the character’s latest incarnation, first introduced Alfred in Batman V Superman.
The actor has called Alfred “A bit of a grease monkey who was very involved in the decisions that Bruce makes” in Batman V Superman.
While Alfred has seen a number of incarnations throughout the history of the Batman franchise from the 1960s series starring Adam West to Gotham‘s Sean Pertwee.
