Extra

Every vampire, when born into Darkness, begins to develop an 'Extra'. Extras are special abilities (many of which are considered super-human in nature) unique to each and every vampire in existence, formed by the emotions and personality traits held by the host before crossing over. Some quiet, shy, or frightened, humans develop 'defensive' extras, while more aggressive and belligerent humans develop 'offensive' ones. A person's life experiences are instrumental in the creation of their particular extra, as is seen when Justin is examined by Char and Becca: "The reason every vampire's extra is different, is because it reflects the kind of people we were when we were alive. Therefore, by looking into your psyche, we'll determine what new surprises we can expect to see as your powers manifest themselves." – Tim, Gone From Daylight: The Beauty and the Darkness.

While it was suggested in chapter 2 of Gone From Daylight: Resurrection that another vampire's extra can be learnt and honed to the same extent as one's own; "We find our own extras, perfect them, and teach them to the people we trust most. They, in turn, teach it to someone they trust, and so on and so on." – Bryson, Gone From Daylight: Resurrection, it has now been confirmed by the author that this does not take place. The explanation that has been provided by the real-life Comicality is that "'certain 'tricks' can be learned or taught by the vampires themselves, the personal experience of having [an extra] of their own can never be surpassed or fully duplicated by another being."

Known Extras
Despite the fact that every single vampire extra is unique and differs slightly for every person, there are some common traits that appear and thus can some vampires be grouped. For example every vampire who is considered to be a Reader has some degree of telepathic and/or mind-reading capability.
