Dr Ma'bor Jetrel
Doctor Ma'bor Jetrel was a Haakonian scientist who led a team of Haakonian Order scientists to create the Metreon Cascade weapon.
In 2355, the Metreon Cascade was used against the Talaxians on the Talaxian moon Rinax hoping to end a decade-long war - the Talaxian government subsequently gave their unconditional surrender the following day, ending the war.
Many Talaxians (and even some Haakonians) developed a deep hatred of Jetrel for having led the team that developed a weapon that caused so many deaths. Jetrel tried to justify himself saying that he was not a monster because he did not use the cascade he 'only' invented it - he called the weapon an inevitable scientific discovery; Jetrel was nonetheless involved. He considered the use of the weapon necessary at the time and he had no regrets in developing it. He only realized the seriousness of what he had done when his wife left him for developing the weapon and his apparent lack of remorse, taking their three children with her - his own casualties of war. Although he had no regrets of developing the cascade, Jetrel spent the remaining years of his life attempting to undo some of the damage by trying to find a cure for the fatal blood disease metremia, a secondary (and unexpected) effect of the Metreon Cascade; he also began work on regenerative fusion. When Jetrel presented his theories on regenerative fusion to the Haakonian Order, he was deemed a Talaxian sympathizer and was exiled from his homeworld.
In 2371, Jetrel encountered the USS Voyager, knowing that Neelix, a Talaxian, was onboard the ship. He wanted to screen Neelix for metremia as Neelix was in one of the scout parties looking for survivors on Rinax. Neelix was extremely uncooperative with Jetrel, blinded by anger at the scientist who invented the weapon that wiped out his entire family. With persuasion from Kes he agreed to be screened; unfortunately, however, he was diagnosed with metremia.
Jetrel was fascinated with Voyager's transporters and studied them in depth. He believed that the transporters could be used to restore the bodies of those vaporised by the Metreon cascade more than fifteen years earlier, effectively bringing them back from the dead. He passed his findings on to Captain Janeway and persuaded her to travel to Rinax to attempt his regenerative fusion experiment. Voyager made its way to Rinax and Jetrel persuaded Janeway to allow him to use the transporters to try to restore those who were killed by the Metreon cascade but his experiment failed. Jetrel then revealed that Neelix did not have metremia - ironically it was he who had metremia and it was in its final stages. Before his death, Neelix forgave Jetrel. (VOY: "Jetrel")
