A seasoned warrior aboard General Martok's bird-of-prey Rotarran who mocks the inexperienced Alexander Rozhenko, fights him in the mess hall and eventually accepts him as a shipmate.
Ch'Targh is a long-serving soldier on the IKS Rotarran, seen in Sons and Daughters and played by Sam Zeller.
In 2374, during the Dominion War, a batch of replacements joins the ship, among them Worf's estranged son Alexander. Ch'Targh sizes up the awkward young recruit at once and needles him in the mess hall until Alexander draws a blade. The veteran is toying with the boy when Worf steps in, which only deepens Alexander's humiliation.
Ch'Targh's attitude is less cruel than it first appears: he regards Alexander's clumsiness as a source of amusement and, in time, something close to good luck for the ship. After the Rotarran defends its convoy against the Jem'Hadar, he is among the crew who welcome Alexander when the young man joins the House of Martok.
