Garmadon

Lord Garmadon is the Master of Destruction, as well as the ninja's archenemy-turned-ally and former mentor. He is the First Spinjitzu Master's firstborn son, Wu's older brother, Misako's former husband, and Lloyd's father. Garmadon grew up learning the art of the ninja alongside his brother, Wu. When he was a child, Garmadon was bitten by the Great Devourer, a serpent corrupted by The Overlord to infect the boy with evil in order for the dark lord to regain a worthy vessel for his return. The effects of the Devourer's venom would lead Garmadon down a darker path through which he would be continually tempted during his time as one of Ninjago's heroes. Around the time of the Serpentine War, Chen had Garmadon sign Wu's love letter for Misako, leading her to choose Garmadon. He and Misako had a son and named him Lloyd, whom he deeply cared for despite his corrupted soul. Ultimately, he lost himself to the venom's influence and became an evil warlord, banished to the Underworld after a climactic battle with Wu. From there, he would hone his skills of manipulation, showed how he let the Ninja to gather most of the Golden Weapons and then lured Kai away from the others so that he would both retrieve the last weapon to then be easier to take it from him, all while Samukai and the other skeletons would retrieve the other weapons by catching the Ninja off-guard. He would also display a mocking sarcasm towards his enemies, relishing in their dilemmas. He was also noticeably vengeful towards his brother, even more so as a result of his banishment and because he blamed Wu for the Great Devourer infecting him. One thing that the venom of the Devourer failed to suppress, however, was his love for Misako and Lloyd; this same quality was enough for Garmadon to briefly side up with Wu in order to rescue Lloyd, even saving Wu several times and genuinely thanking him for watching over Lloyd.
