Fan Casting Samukai in Ninjago

Samukai was a fearsome Skulkin general with four arms. At some point, he died and was reborn as a Skulkin in the Underworld where he united the army of the undead and became their king. Upon Garmadon's banishment, Garmadon took over the Underworld and became the realm's new ruler. Nonetheless, Samukai retained a position high on the Underworld hierarchy as Garmadon's second-in-command and retaining the title of "King of the Underworld" while carrying out his superior's will.
