All Alpha humans can be identified by diamond shaped blotchy markings on their backs located between the shoulder blades often assumed to be "ordinary" birthmarks. Siginificantly all Alphas are immune to the disease and ailments that trouble ordinary humans.
When the transition starts the individual will suddenly develop a skin irritation all over their body, sometimes accompanied by a rash but not always. At the same time the person will develop a sensitiity to bright light. For most Alpha Inferiors the unexpected "illness" is often quite a shock since they would never have experienced anything like it before. The itchyness and light sensitivity will then remain for a few weeks and then dissipate at which point the individual often assumes they have returned to normal. The person though will in fact be an Alpha Superior but their "special" gifts will not be active until they are triggered for the first time by an outside stimulus (see below.)
Once the trigger is initiated the Alpha Superior will then inadvertantly use their Alpja ability for the first time. Since each person is different and the Alpha ability is not known (except in rare cases) the unexpected result of doing this can be highly dangerous for the individual and/or bystanders depending on the nature of the Alpha ability.
After this trigger event is over the Alpha Superior will then be able to access their Alpha ability simply by thinking about using their newly acquired "ability" and no emotional responce is required.
In most cases an Alpha ability is used via conscious thought which is used to "turn it on and off". Some Alphas can do this as an almost instincive responce. The one major problem all Alpha Superior's face is the fact they cannot use their "gifts" permanently because when they are active they cause a drain on the human body's energy resources. Essentially this means once they get tired they can no longer use their Alpha ability and if they do try to fight their body's natural responce to "turning off" their Alpha ability they will collapse. In some situations Alphas who have done this have encountered "burnout" whereby they collapse and even after recovery they can no longer "access" their ability for days or even weeks.
Interestingly the type of ability and how it is used is often the limiter in how long a person can use their gift. An Alpha with a far less powerful ability can use their gift for very much longer, hours or even days at a time than a more powerful Alpha who at maximum "output" might only manage a couple of minutes before experiencing fatigue.
Note: Some Alphas do not have the means to shut off their Alpha ability and it is permanently active. Though they do not experience "burnout" their bodies are placed under permanent strain and they very often have to take great care to manage their condition because if they do not they will die by the simple fact the human body cannot cope and will literally tear itself apart from the inside.
