Samukai

Samukai was a fearsome Skulkin general with four arms. After he fought against Wu and Garmadon, Samukai was banished to the Underworld, where he united an army of the undead and became their king. Upon Garmadon's banishment, Samukai threatened him but was ultimately ridden of his title, as Garmadon became the realm's new ruler. Nonetheless, Samukai retained a position high on the Underworld hierarchy as Garmadon's lieutenant and the Skulkin general of Fire, carrying out his superior's will.
