Ninjago season nine

Shade / Shadow (Shadow Master): Secretive, silent, slightly cynical, and a loner by nature. He has a hard time trusting others, but once he's committed, he sticks to his guns. The perfect stealth fighter.
Paleman / Mister Pale (Master of Light): Quiet, modest, and doesn't like to attract unnecessary attention (ironic for his element). A reliable team player.
Toxo (Poison Master): An eccentric, sharp-tongued, brash, and emotionally charged character. She's not afraid to speak her mind, even to Lloyd's face, but she doesn't hesitate to embark on dangerous missions.

Karlof (Metal Master): A straightforward, loud, and somewhat blunt good-natured man. He prefers to solve problems with force and has a stubborn nature, but is incredibly loyal to the Resistance and is ready to bear the brunt of the attack.
Griffin Turner (Master of Speed): Bold, self-assured, nimble, and slightly egocentric. He likes to boast about his skills, but in guerrilla warfare, he becomes an excellent scout and messenger.
Neuro (Master Mind): Calm, wise, reserved, and observant. Prefers to think and analyze the enemy's thoughts before engaging in combat. Works as the Resistance's chief analyst.

Jay: The team's source of panic and humor, but with a kind heart. He's easily stressed out in the unknown world of Oni and Dragons, prone to drama, but always shows courage in crucial moments. His emotional side helps the team stay focused.
Zane: An analytical, kind, and self-sacrificing Nindroid. He relies on logic and calculates probabilities, but possesses a deep humanity. In the wild, he acts as the group's "compass" and strategic brain, maintaining absolute calm.
Little Wu: A rapidly growing child with subconscious fragments of the old Sage's wisdom. Curious, playful, but occasionally displays the makings of a great martial arts master, grasping the essence of balance.

Lloyd Garmadon: He suffers from severe psychological trauma. Due to the loss of his powers and the apparent death of his friends, he feels despair and guilt. However, the true core of a leader emerges within him: he learns to be strong not through the elements, but through willpower. He is selfless, protecting the weak to the last.
Niya: A fighter, logician, and the team's mainstay in Ninjago City. She's strong-willed, stubborn, and doesn't tolerate panic. In times of crisis, she takes on the role of the Resistance's driving force, supporting Lloyd and finding solutions to technical and strategic impasses.
Kai: Impulsive, hot-blooded, but incredibly loyal. He loses his temper quickly, especially when the team finds itself in a desperate situation in the Realm of Oni and Dragons. He is driven by his overprotectiveness of his loved ones and his desire to fight, even when the odds are against him.
Cole: Grounded, reliable, reasonable, and caring. In the Realm of Oni and Dragons, Cole takes on the role of "parent" to Little Wu. Calm in critical moments, possessing high moral fortitude, and never abandoning his comrades.

Killow: An imposing giant who serves as the gang's strongman. Loyal to Garmadon and Harumi, he respects only brute force and discipline within the gang. Disinclined to subtle strategies, he prefers to dominate the battlefield with his size and the Mask of Deception.
Ultraviolet: A mad, hyperactive, and psychopathic warrior. She takes genuine pleasure in chaos, violence, and the suffering of others. She often laughs loudly, acts impulsively and unpredictably, especially under the influence of the Mask of Hatred. She enjoys taunting her enemies.
Mr. E: A silent, cold, and highly efficient Nindroid. He never speaks, expressing emotion solely through combat. He is calculating, quick, completely fearless, and acts with machine-like precision.
Skylor (Implementation/Character): Pragmatic, strong, independent, and loyal to her friends. She possesses high self-control and maintains a cool head in crisis situations.

Lord Garmadon (Oni Form): Completely devoid of empathy, paternal love, or humanity. He is driven solely by the thirst for destruction and war. In this form, he views strength as the only law of the universe: "Only when you fight do you live." He considers Lloyd weak because of his compassion. He is arrogant, cruel, blunt, and gains power during battle, feeding on the fear and aggression of his enemies.
Princess Harumi (the Silent Emperor): A brilliant manipulator who hides an icy hatred behind a mask of meekness. She suffers from deep psychological trauma following the death of her parents. Cold-blooded, calculating, and fanatical. She masterfully gains trust (as she did with Lloyd), exploits others' weaknesses, and shows no mercy for traitors. Her main goal is to give Garmadon absolute power so that Ninjago will never again know the chaos of ninja inaction.

The Elemental Masters gathered at the junkyard to fight Garmadon:
Karlof: Master of Metal. A giant builder from Metalonia, he transforms leather into steel.
Griffin Turner: Master of Speed. Capable of moving at superhuman speeds.
Neuro: Master of the Mind. Can read minds and influence consciousness.
Shade: Master of Shadow. Able to merge with and move through shadows.
Paleman (Mr. Pale): Master of Light. Can become completely invisible and refract light.
Toxo: Master of Poison. Capable of creating toxic vapors and acids.
Jacob Jewreychik: Sound Master (depending on timeline/support).

Kai (Master of Fire), Jay (Master of Lightning), Zane (Master of Ice), and Cole (Master of Earth) survived by using the Magical Tea of ​​Appearance, which transported them to the Primordial World.
Along with them is Baby Wu (Master Wu, reborn as an infant at the end of Season 7), who is growing rapidly. The ninja survive in the wilderness, battle the Dragon Hunters led by Iron Baron, and try to restore Wu's memory and strength so he can return home.

Lloyd Garmadon: The Green Ninja, son of Garmadon. Depressed by his loss of powers and believing his friends dead, he learns to lead the Resistance without elemental energy, demonstrating leadership and resilience.
Niya: Master of Water. The Resistance's mainstay, tech specialist, and fighter. She looks after Lloyd and keeps the team together.
Misako: Lloyd's mother, a researcher and strategist. She helps coordinate the headquarters' activities.
P.I.X.V.Z. (PIXAL / Samurai X): An artificial intelligence in the physical body of a samurai. Provides technical reconnaissance and support.

A criminal biker gang that has seized power in Ninjago City under the leadership of the Silent Emperor.
Key figures:
The Silent Emperor (Princess Harumi): The secret leader. An orphan who lost her parents to the Great Devourer. Blames the Ninja for her tragedy and idolizes Garmadon for defeating the serpent. Manipulative, cruel, and intelligent.
Killow: A giant strongman who wields the Mask of Deception (which grants telekinesis).
Ultraviolet: A mad, chaotic warrior who uses the Mask of Hatred.
Mr. E: A silent Nindroid ninja who wielded the Mask of Vengeance.

Oni and Dragons: The two primordial races of the Primeval World. Dragons create, Oni destroy. The Firstborn Spinjitzu Master was a hybrid of an Oni and a Dragon.
Garmadon's Story: The eldest son of the Original Spinjitzu Master and Wu's brother. As a child, he was bitten by the Great Devourer, infusing him with pure evil venom. Slowly transforming into a monster, he became Lord Garmadon. He later purged himself of evil and became Master Garmadon, but sacrificed himself by entering the Cursed Realm.
Resurrection (Season 8): Princess Harumi, using the three Oni Masks, resurrected Garmadon, but only his dark, destructive Oni self. Garmadon is now a merciless tyrant with no love for his son, drawing strength from battle and destruction.

Current location: Ninjago City Junkyard, hidden Resistance base.
Context: Lord Garmadon has been resurrected in his pure demonic form and has taken over Ninjago City with the help of the Sons of Garmadon gang. Lloyd lost his elemental energy after his battle with his father and believed his friends had died in a building collapse.
The current state of affairs: Kai, Jay, Zane, Cole, and the infant Baby Wu (a rapidly growing Wu) survived, but are trapped in the Realm of Oni and Dragons. In Ninjago City, Lloyd, Nya, Misako, and the surviving Elemental Masters form an underground Resistance to wage guerrilla warfare against the regime of Garmadon and the Silent Emperor (Harumi).
