Neither. Hancock is the only superhero movie this summer of 2008 that's not based on a previously established comic book. The screenwriter Vincent Ngo wrote the script, originally titled Tonight, He Comes, in 1996, but it got passed around from director to director until Peter Berg took it over in October of 2006. After several rewrites and a change of title, Hancock finally began filming in July of 2007.
No, Hancock (Will Smith) is not an alien. He's described in the film as one of the last survivors of an ancient race of angels that died out because they had the unfortunate tendency to become mortal when near each other for long.
Some viewers claim that Mary Embrey (Charlize Theron) is the villain. Others name Ray Embrey (Jason Bateman) as the villain. The most obvious villains are a trio of escaped convicts--Red (Eddie Marsan), Mountain (David Mattey), and Matrix (Maetrix Fitten)--who hold a grudge against Hancock for putting them behind bars. However, part of the subversion of the genre that Hancock engages in is that Hancock is the true villain of the piece, as well as the hero. The person he truly has to fight is himself; the person who causes all the troubles in his life is himself; the person who perpetuates the cycles of violence in his life is himself. Since the film turns the idea of a Hero on its head, as well as the idea of a Villain, it's very hard to assign the role to any one character.
There is a small scene during the credits, but nothing after. The audience is caught unawares as they are leaving the hall. Everybody just stops where they are to watch the scene.
