Alfred Bester Species: Human - Telepath Age: unknown Psi Cop [played by Walter Koenig]

A member of Psi Corps from the age of ten.  He is based on Mars Colony where he has a wife and daughter in a loveless marriage arranged by Psi Corps. Psi Cop Bester's first of several visits to Babylon 5 was when he was assigned with another Psi Cop, Kelsey, to capture Jason Ironheart but was thwarted when Ironheart evolved into a higher level of being as a result of delays caused by Commander Sinclair's lack of co-operation. Partly out of revenge for this he later sent his friend Ari Ben Zayn to investigate the command staff of Babylon 5 along with a Psi Corps aide Harriman Gray. Bester returned to Babylon 5 while hunting for the underground railroad of rogue telepaths passing through the station organized by Dr. Stephen Franklin, only to be apparently tricked by Talia Winters and the other rogue telepaths into believing he had killed the rogues. Bester returned on another clean-up operation in 2260, passing through the gun sight of Susan Ivanova as she targeted his approaching transport with Babylon 5's defense grid rather than let him dock. However Sheridan was able to prevented her from firing at his ship. Once aboard, and prevented from scanning any of the command staff first by a shield of Minbari telepaths and then by an injection of Sleepers (a drug which temporarily shuts down the telepathic ability) he enlisted Michael Garibaldi into helping him in the pursuit of Dust smugglers during which they managed to establish a good professional relationship, if not a friendly one. Later that year he returned alone in a Black Omega Starfury to Babylon 5 with the news that a transport containing "weapons components" was bound for the rim where they were to be used by the allies of President Clark, the Shadows, and seeking John Sheridan's help in stopping this delivery taking place. In reality, these components were telepaths, programmed by allies of the Shadows to be the central processing core of the Shadow ships by the use of cybernetic implants in their heads. When Bester discovered that one of these altered telepaths was his lover Carolyn, he declared that "my enemy's enemy is my friend" and offered to form an alliance with Sheridan, stating that he would do anything if they would help Carolyn recover. "Anything" extended to sacrificing his prized creation of Black Omega squadron to the mercy of an attack by forces from Babylon 5 in return for John Sheridan taking him to Z'ha'dum in order to search the supposedly abandoned world for clues to the technology used to condition her mind, only to have his plans turn to dust when the fleeing allies of the Shadows destroyed the planet. Bester is prepared to go to extraordinary lengths to protect "his telepaths" from harm, as seen in his manipulation of Michael Garibaldi to discover the truth behind rumors he had heard of an anti-telepath virus that he suspected William Edgars had developed. Having had the good fortune to come across Garibaldi following his capture outside Babylon 5 by the Shadows and subsequent handing over to EarthGov, he managed to get his own team assigned and covertly move Garibaldi to the Psi Corps installation at Syria Planum for reprogramming. Once this was accomplished Bester manipulated Garibaldi out of his job as Babylon 5's Chief of Security and into a new role within Edgar's organization where he gained the information that Bester sought about the anti-telepath virus, which was duly reported back to Bester by his spy. With the proof of intent that Garibaldi provided, William Edgars was no longer considered untouchable due to his status and was killed by a Psi Cop strike team, along with his assistant Wade and two security guards. Garibaldi meanwhile was given his life and memories back, although as Bester commented; the knowledge of what he had unknowingly done to John Sheridan might actually be worse than Bester's alternative plan for him, namely a killing shot from a PPG.

Mr. Morden (no first name given) Species: Human Age: unknown Archeolinguist Shadow Agent [played by Ed Wasser]

A human archeolinguist who was employed by Earth Force's New Technologies Division and spent a lot of time exploring the rim. He was assigned to the Icarus mission to Z'Ha'Dum under the supervision of Dr. Chang and along with Anna Sheridan. Like Dr.Chang, the missions' supervisor, Morden was aware of the background to the mission, having theorized that the Shadow Warship excavated from Syria Planum by Dr. Mary Kirkish's team had flown to Z'ha'dum on automatic and then gone dormant as IPX's probe had failed to detect any sign of activity on the planet. Morden became the first known survivor of the destruction of the Icarus when he appeared working as an agent for the Shadows on Babylon 5 by acting as their liaison to Londo Mollari, who was selected as the Shadows' agent of unrest after each of the principle alien ambassadors to Babylon 5 was asked the question "what do you want?" by Morden. While Ambassador Kosh and Delenn refused to discuss the question with him, and G'Kar only wanted the Centauri destroyed and safety for his people, Londo's response was much more grandiose, expressing a lust for the past glories of the Centauri Republic and a desire to return to having things the way that they were, perfect for what the Shadows wanted. Morden is never alone, at least two Shadows accompany him, both for Morden's protection and to prevent Morden revealing the existence of the Shadows to others, although he is of enough importance to the Centauri that they were prepared to extend him diplomatic immunity when he was arrested at the behest of John Sheridan. Besides liaising with Londo Mollari, Morden also has associations with Lord Refa, members of Psi Corps and EarthGov, most notably President Clark, for whom he helped arrange the destruction of Earth Force One, resulting in the death of President Luis Santiago. Morden narrowly escaped death in the explosion, that killed Justin and Anna Sheridan, when the White Star with its cargo of  two thermo-nuclear bombs detonated above the Shadows' complex beneath the surface of Z'ha'dum. Badly burnt and scarred by the blast he traveled to Centauri Prime to negotiate the stationing of Shadow Warships on Centauri Prime with Cartagia, also requesting that Londo Mollari be reassigned there as an "Advisor on Planetary Security" so that he might act as liaison between the Centaurum and the Shadows. Shortly afterward however Londo finally discovered the truth about the death of Adira Tyree; that it was Morden, and not Lord Refa who was responsible for her being poisoned. After his initial fit of rage at the ease Morden had manipulated him, Londo had Morden brought before him, demanding that he remove the Shadow fleet from Celini, and when he refused, Londo first destroyed the island and then had Morden beheaded. When Morden's spirit visited Lennier during the Brakiri "Day of the Dead" some months later he revealed that his head was still there and that he had just tried to make people happy, but more importantly that Lennier would betray the Anla'Shok and hinted that Lennier too might soon be dead.

Emperor Catargia Species: Centauri Age: unknown Emperor of the Centauri Republic [played by Wortham Krimmer]

The nephew of the late Centauri Emperor Turhan, who became his successor following his death on Babylon 5 in the middle of 2259, chosen for the ease with which he could be manipulated by Lord Refa who would retain control of the real power behind the throne. The best laid plans of mice and Centauri however did not quite work out as expected, Cartagia was in fact quite mad and with Lord Refa's death on Narn he was given free reign to pursue his deluded dreams of becoming a living God, dealing with the Shadows via Morden who he believed were those spoken of in ancient books who had deified the first Centauri Emperors. In return for his apotheosis Cartagia agreed to allow the Shadows to station over one hundred of their warships on the island of Celini on Centauri Prime, silencing the objections of sixteen ministers by having them enter his "Shadow Cabinet" a gruesome collection of severed heads that he kept arranged on a desk and spoke to late at night. This kind of response was typical of Cartagia, who would turn on a whim from one mood to another, usually resulting in an execution, when he became bored or something was not done to his satisfaction. The life of others meant little to Cartagia, who took great pleasure in the torture of the captive G'Kar, to the extent of getting his own hands bloody in pursuit of extracting a scream from the Narn and plucking out an eye because he did not like the way he was being looked at, and even being prepared to sacrifice all of the Centauri people if that was required to obtain the status of a God. Cartagia eventually met his fate on Narn, where he had been urged by Londo Mollari, ostensibly to stage a show trial of G'Kar to demoralize the Narn and demonstrate Centauri justice, but in reality to render him vulnerable to assassination. Cartagia was quick to agree to this plan and swiftly sentenced G'Kar to death by vivisection only to have G'Kar break free from his kirillium bonds, despite the specially weakened chains used by Londo having been replaced, and in the confusion was ushered unnoticed from the throne room by Londo. Before he could be stabbed and poisoned however, a scuffle ensued causing Londo to drop his needle of neurotoxin, only to be accidentally stabbed by Vir Cotto who had followed the pair and was holding the needle when Cartagia stumbled into it. As Cartagia had left no heirs to succeed him, and there was no time to decide on an alternative before the Vorlon Planet Killer arrived at Centauri Prime, Londo Mollari was appointed as Prime Minister of the Centauri Republic.

Lord Refa Species: Centauri Age: unknown Representative of the Centaurum [played by William Forward]

A former Lord in the Centauri Republic and a representative of the Centaurum who used his alliance with Londo Mollari to further his own ends towards becoming the Centauri Emperor. He was responsible for the murder of Prime Minister Malachi and the one who put the resolution to denounce Urza Jaddo as a traitor to the Centaurum. Lord Refa also controlled Cartagia during the early stages of his reign as Emperor, leading him into initializing conflicts on twelve fronts with the aid of the Shadows to "provide room for expansion". Upon the discovery that he had formed an alliance with Morden, Lord Refa was partly poisoned by Londo Mollari in such a way that the poison administered would lie dormant until a second trigger was ingested, which would occur if he did not disassociate himself from Morden, at which point, the two parts of the poison would meet in Lord Refa's cardiovascular system and "hold a little party" upon which, Lord Refa would be very dead. Londo's argument was persuasive, and Lord Refa arranged the partial withdrawal of Centauri forces, refusing to meet with Morden, much to the frustration of the Shadows, who required the Centauri Republic to continue its advance. Morden's solution to the problem was to have Londo Mollari's lover, Adira Tyree, murdered in such a way as to make it appear that Lord Refa was responsible, with the result the Londo swore to revenge himself on Refa and requested the help of Morden and his associates. Despite this Londo gained his revenge without Morden's assistance, using a complex plot to both destroy Refa and clear his way to eventually becoming the Centauri Emperor, using his knowledge of the fact that Refa had brought a telepath with him when he came to Babylon 5 with Minister Virini in an attempt by Virini to settle their dispute. Supplying his attaché, Vir Cotto, with a false plan that he intended to capture G'Kar on Narn while he was rescuing his own former attaché, Na'Toth, knowing that Refa would telepathically take it from him, Londo then arranged for Refa's ultimate betrayal, ensuring that Refa would be assigned guards loyal to himself by Lord Drigo, the Centauri Governor of Narn. Deep in the catacombs beneath the former seat of the Kha'Ri Refa was turned over to the Narn resistance movement, who had been informed by G'Kar and Londo Mollari that he was responsible for the bombing of Narn and the subsequent creation of work camps, claiming millions of Narn lives. When his body was finally recovered by the Centauri they found a faked data crystal implicating Refa in colluding with the Narn resistance in an attempt to destabilize the Centauri Republic and move his own allies into positions of power, a plan that had clearly fatally backfired.
