Alfred Pennyworth

Alfred Pennyworth, after a varied career, was employed as the Wayne family's butler when Bruce Wayne's parents were killed. Alfred raised the young orphan and reluctantly aided him in his quest to become the Batman. His many skills - ranging from cooking to medicine - make him Batman's staunchest ally, along with a formal demeanor that grounds the Dark Knight and deflects those who might otherwise suspect Bruce Wayne's true identity.

Batman: Arkham City
Alfred was Batman's main person for communications whilst he is in Arkham City. He was able to contact Bruce, stating that there was more interference then usual. He sent Batwing (which contained batsuit) to fly over Arkham City and dropped the batsuit container on the roof of Ace Chemicals building. Batman hacked into TYGER's communications, learning that Catwoman was being held hostage by Two-Face, with Alfred saying that Two-Face will kill Selina.

After learning that the Joker had tried to assassinate Catwoman, Batman headed to Steel Mill. However, he was poisoned by Joker with his own Titan virus. With Batman now poisoned, Alfred suggested to find Freeze, who was working on a cure. Batman also learned that Deadshot was in Arkham City and killing people who had worked for Strange, with Alfred believing he was an inmate there, although Batman believed otherwise.

When Batman arrived to Penguin's museum, he learned that he was in possession of Titan, with suddenly Oracle interrupting the two. Batman told Alfred to fill in Oracle what had happened in Arkham City thus far, with Alfred starting to working on it.

When Hugo Strange unleashed Protocal 10 (which turned out to be plan to wipe out Gotham City out of all criminals), Batman attended to save Talia al Ghul, who was with the Joker. However, Alfred persuaded Batman to save people in Arkham City first, as the prison was not only containing criminals, but also people who had proves against Strange's crimes. While Batman was stopping Protocol 10, Strange sent a group of TYGER guards to Wayne Manor to find out the rest of Batman's secrets and kill his loved ones putting Alfred in danger only to be rescued by Robin and Nightwing who easily defeated the TYGER guards.
