Garos
Garos was a Malurian who posed as an Akaali in order to conduct covert mining operations on their homeworld. 

In 2151, his mining operations had contaminated the water supply of the planet and had caused a mysterious disease among the Akaali. He owned a curio shop as a cover for his operations, but was discovered by Captain Jonathan Archer, who enlisted the help of a local apothecary named Riaan. 

In the beginning, Garos was welcoming Archer and  to his curio shop of antiques. After that, he presented "the pride of his collection," the mask of Draylan, the mythical ruler of the afterworld. When Tucker seemed astonished, Garos said, "You're not from this province, are you?" Archer answered "No" and revealed that Garos' DNA didn't match any of the lifeforms on the planet; Garos took out his own scanner and said "Nor does yours." Garos revealed to Archer that he was from the Malurian system and was an explorer until two years prior, when he led a survey team to study the Akaali, and noted that he had had no plans to remain, but after a few months, found himself "quite taken with these people." Then, when Archer confronted Garos about the antimatter reactor in his basement, he lied by responding that the reactor ed a fabrication device, allowing him to make food and clothing. Then, Garos coaxed Archer to leave his shop after another interested visitor arrived. 

When Archer and Riaan discovered Garos' secret mining facility, Garos and his henchmen tried to prevent Archer from escaping. In doing so, he hailed (and lied again)  and said that Archer has been killed. Later, when Archer and Riaan tried to leave unnoticed, another Malurian fired his pistol, antagonizing the Akaali crowd. Quickly, Garos and his fellow disguised Malurian rushed into the chaotic mob of people and Garos fired his weapon in order to kill or incapacitate Archer. However, Archer used Riaan's help after he fired at an oil lamp, causing an explosion that temporarily knocked out Garos and his henchman, forcing them to transport back to their ship. Archer was subsequently able to drive Garos and the rest of the Malurians off the planet, remove the mining equipment and provide an antidote for the disease. ()
