Alphas are ordinary people with extraordinary abilities. Impossible is what they do best. Doctor Rosen has observed Alphas in the following categories:

Hyperadrenal Alphas possess extraordinary physical abilities that are activated by elevated levels of adrenaline. When hyperadrenals are in the "zone" they have high thresholds for pain and are unstoppable, but when the adrenaline rush ends, they become listless and physically drained.

Transducer Alphas are human antennas that possess the ability to intercept communications and encrypted messages with their minds.

For Hyperkinetic Alphas, the mind's imaging systems and muscle control are perfectly in tune with the motor skills center of the brain. Hyperkinetics possesses flawless aim, perfect balance, and greatly enhanced motor skills.

Synesthete Alphas are able to enhance one of their five senses, such as sight or hearing, while rendering the remaining senses temporarily useless - often leaving them vulnerable to danger.

Influencer Alphas disrupt other people's abilities to make decisions.  Influencer/Pushers use mental weakness as an opportunity to get what they want in any situation.

Dr. Lee Rosen is a preeminent neurologist and psychiatrist with a long history of hands-on work with patients suffering from neurological disorders. His fascination with Alphas—ordinary people with very extraordinary abilities known as Alpha Skills—has led to the formation of a group of highly evolved humans specializing in solving Alpha-related cases. Though not an Alpha himself, he has become the unconventional leader of the team and his nurturing personality and fatherly wisdom are instrumental in holding the group together when stresses and personality conflicts threaten to tear them apart.
