According to the Ninjago Official Guide , Wu and Garmadon defeated Samukai before Garmadon turned evil . When Garmadon was banished to the Underworld , Samukai attempted to kill him , but was himself defeated and deposed , though he remained Garmadon ' s general . Before he started attacking Ninjago , Samukai looked up Zane ' s father , Dr . Julien , and revived him with a potion . Samukai forced him to build powerful vehicles that would aid him with his attack , and when he refused , he was locked in a deserted lighthouse in the middle of the sea . Years later , he lead an assault on the Four Weapons Blacksmith shop to find the map to the four Golden Weapons . He fought Kai one on one for a small amount of time before subduing him , but before he could finish him off , Sensei Wu intervened . Samukai then used his daggers to make a large water tower begin to fall on Kai , leaving Sensei Wu with a choice : Rescue Kai , or capture Samukai . Samukai used the distraction to capture Nya , and escape in his Skull Truck . He and his army stole the map from Kai and Nya ' s shop that leads to the four weapons . The ninjas , Cole , Jay , Zane , and Kai , later steal the map back . He then went to find the first Golden Weapon , the Scythe of Quakes , hidden in the Caves of Despair . However , Nuckal read the map upside down , and was digging in the wrong place . After the four Ninja accidentally gave away their presence , he took his army in to fight them and claim the Golden Weapon . Soon after the Ninja discovered Spinjitzu during the battle , he called a retreat , as he could not fight four Spinjitzu masters and the Earth Dragon appeared . Garmadon then gave Samukai new orders : Let the Ninja think they ' re winning . Samukai continued to seek the Golden Weapons , but allowed the Ninja to dominate until just before they began to search for the Sword of Fire . Then , Garmadon ' s scheme came into play . Kai was lured away from the rest of the group , and Sensei Wu followed . Samukai and his army then ambushed Jay , Zane and Cole , claiming the Shurikens of Ice , the Scythe of Quakes , and the Nunchucks of Lightning for Garmadon . Garmadon then sent him back to the Underworld , where he fought Sensei Wu , who was wielding the Sword of Fire . Samukai defeated him , and took up the Sword , intending to use the Four Weapons and their power to defeat Garmadon and regain control of the Underworld . However , the power of the Four Weapons united was too much for anyone to handle , and as a result , Samukai disintegrates and The Portal through space and time appears , which was Garmadon ' s true plan all along . Having succeeded in his plan , Garmadon then escapes through the Portal vowing to return with more power so that he can wield the Four Weapons and recreate Ninjago in his own image . Samukai is one of the villains revived by Sensei Yang during Day of the Departed . He , alongside two Skulkin warriors , attacks Jay at his parents ' junkyard , but Jay is helped by Ronin , who had come with plans of stealing the place .
