Brota
Brota was a hybrid who existed in an alternate timeline on the planet Gaia. He was a descendant of Worf and Jadzia Dax. 

He was the leader of the Sons of Mogh, a group which followed Klingon ways to honor their ancestor. He asked Worf to kill him rather than let him be simply wiped from existence when the  left. Worf initially promised to do so, but later appeased his sense of honor by giving him and the others a heroic task to complete; planting the fields before they ceased to exist. ()
