Rebecca Madison

Chairperson of Maximum Inc. and widow of Maxwell Madison Sr., the 23rd Phantom's killer, Rebecca plans to construct Cyberville, a technological and impenetrable fortress where the select wealthy and elite may seek refuge when the Earth begins to deteriorate (something Rebecca's underground biot army will ensure takes place relatively soon). She represents the greatest threat to the world in 2040.

Other than Graft and her son, Maxwell Madison Jr., no other humans are employed by Maximum, which has its own army of BIOTs perform all labour.

Maxwell Madison Jr.

Rebecca's psychopathic son whose intelligence is belied by his laziness and outward disinterest in almost everything. When he does have an opinion on something, he presents it as coming from his cat Baudelaire, named after philosopher Charles Baudelaire.

He is psychologically disturbed with the disorders being rooted in the loss of his father at such an early age. His cat, perhaps the last remaining symbol of his father's love for him, is his only and most trusted friend.

Hubert Graft

Rebecca Madison's Chief of Security and main enforcer. A cyborg, he was formerly an environmentalist who fought against Maximum to protect the Amazon rainforest, before losing his whole body below the shoulders in combat. Maximum rebuilt Graft's body using BIOT parts, giving Rebecca Madison complete control over Graft's life.

Graft's BIOT torso can be disconnected (a painful process) at the hip and integrated into other robotic systems over which Graft has complete control, most commonly the Urban Combat BIOT Walker, a ten-foot steel exoskeleton armed with lasers and claws.

Despite this, he still has a desire to protect nature. Several times the Phantom offers Graf help to escape Maximum's clutches, but Graft always turns this offer down. He also is against harming children, even if that child trespassed and destroyed invaluable company technology.

Dr. Jak

A cynical sensationalist TV yellow journalist who reports on the Phantom's activities with a negative spin. His arrogance and vanity bring him to believe that rather than being merely a reporter of news, he "is the news", and therefore anything he does not see did not happen.

Jak's wife perished in the Grand Central Station crash, after which Jak attempted an illegal operation to integrate an analytical computer into his mind to aid him in finding the truth behind his wife's death. However, the operation was interrupted and the analytical program thought lost. Dr. Jak was left part-BIOT, with sensory implants in his head and a multi-purpose eyepiece which he uses to film his news program, The Dr. Jak Show.

Sean One

The first human born in outer space and founder and leader of the Free Orbital Movement, Sean One seeks independence for his Orbital colonies.

An arrogant and abnormally tall man, he resorts to espionage and terrorist attacks to achieve his ends and is unable to walk by himself while in the presence of gravity. He is revered among the Orbitals' inhabitants in an almost god-like way and is extremely apathetic towards people born on Earth, whom he calls the "gravity-slaves."

Gorda

A morbidly obese crime lord and smuggler from Australia. Unable to move by herself, she has an army of strong, red-tinted biots under her command. Sheengages contacts via a virtual camera system, and has a well-armed robotic kangaroo as her sole companion.

Maxwell Madison Sr.

Rebecca's deceased husban, who was killed along with the 23rd Phantom in a toxic train wreck. Rebecca captures his brainwaves and stores them in an enormous computer, constantly seeking a stable way to transfer them into a BIOT or, preferably, a living body to effectively resurrect her husband.

Regarded as a very dangerous and power-hungry man when alive and in control of Maximum Inc., it was discovered that his plans for the world were very ecologically beneficial. However, his ambitious wife Rebecca sabotaged those plans in favour of greed and world domination.

Queen Nia

A would-be queen of Egypt, Nia seeks revenge on the Phantom for "stealing" her kingdom from her after he helped unify all of Afria into one country.
