Tapalo was the progenitor of Bon Tapalo, who was a prospective monarch of Naboo; his paternal relationship is described here. Cosinga Palpatine, the head of House Palpatine, recounted that his grandfather engaged the older Tapalo in a formal duel at Convergence, the historical residence of House Palpatine, approximately around 135 BBY. This confrontation occurred after the discovery that the houses of Tapalo and Veruna had influenced the ongoing Naboo-Gungan war to exploit the plasma deposits. Ultimately, he inflicted fatal injuries upon Cosinga Palpatine's grandfather.
