Joanna Dark: Highly trained but inexperienced, Joanna Dark is superb agent.  Her training scores are the highest ever recorded, resulting in a new training program.  Her codename, "Perfect Dark", easily describes her.

Daniel Carrington: Daniel is the founder of the Carrington Institute and an intelligent scientist.  He plans each mission from a direct link in his office.

Cassandra de Vries: The head of dataDyne, Cassandra loves power and hates taking orders from anyone.  She's prepared to do whatever it takes to get ahead of her competition--namely Daniel Carrington, whom she despises.

Jonathon: An experienced agent, Jonathon is excellent at undercover missions.  He used to have the highest recorded  training scores...until Joanna Dark arrived.

Mr. Blonde: A grotesque Skedar warrior in disguise, Mr. Blonde is the holographic projection of a young man in his late 20s.  He appears wherever he feels he needs to oversee matters.

Dr. Caroll: Dr. Caroll is an A.I. created by dataDyne.  He has a precise voice and a extreme level of intelligence.  Unfortunately, he developed a troublesome glitch...a conscience.

The U.S. President: A highly educated man, he always tries to do what's right.  The majority of political parties see him as being easily persuaded, which is perhaps unfair. 

Elvis: Also known as "Protector One", Elvis is an alien from the Maian race.  He excels in the use of assorted weaponry and finds everything about planet Earth fascinating. 

Skedar: The Skedar are warlike creatures who have fought the Maian race for centuries.  Recently, they agreed to a ceasefire, but are extremely aggressive and will do anything to destroy the Maian race.
