A Mari man who beats a stranger in a marketplace in 2374 after brushing against B'Elanna Torres, whose fleeting angry thought is blamed for the assault.
Frane is a citizen of the Mari, a telepathic society that has all but eliminated crime by outlawing violent thoughts. He appears in the fourth-season Voyager episode Random Thoughts.
While Voyager's crew are trading on the Mari homeworld, Frane bumps into Torres and she feels a brief flash of temper. Soon afterwards he savagely attacks another man. The chief examiner Nimira concludes that Torres's thought infected him and sentences her to have it surgically removed.
Tuvok discovers that Frane had already been treated more than once for violent thoughts, which leads him to an illicit trade in forbidden mental images run by the merchant Guill, who had deliberately provoked Torres to harvest her anger.
