Samukai

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 the retaining the title of "King of the Underworld" while carrying out his superior's will.

Samukai and the Skulkin fought against the ninja and claimed the Golden Weapons. When Samukai confronted Wu, he took hold of all four weapons, but their immense powers vaporized him and created a portal. Garmadon then escaped the Underworld and wreaked havoc in Ninjago.
