9. Alfred Pennyworth

Alfred Pennyworth is a former MI7 butt-kicker with intense acting and combat training.

Basically, this guy was fully equipped to be a night-stalking vigilante in his own right, but instead of doing that, he did something better: He raised Bruce Wayne. After the deaths of Thomas and Martha, Alfred raised Bruce to be a good kid, allowing him to train and study the way he wanted to.

When Bruce decided to dress up like a giant Bat and punch people in the throat, Alfred was supportive. For years, he attempted to keep Bruce on a healthy path, and encouraged him to not stray into the darkness that fringed his soul. He was always there for him.

Whether he was monitoring Jean-Paul Valley to make sure he wasn't going to build a bat-shaped murder suit (he was), or forming a new team of Outsiders to compensate for Batman's apparent death, Alfie was a preeminent part of the Bat team, now and forever.
