Ninjago: Masters of Spinjitzu Season 12 Episode 8

As the ninja and Okino approach the Maze of the Red Dragon, Unagami uses his control over Prime Empire to briefly “pause” all the players except Okino. He appears before Okino, urging Okino to betray the ninja and not help them against the fearsome Red Dragon that awaits the ninja at the heart of the maze. If Okino betrays them, Unagami promises to bring him with into the real world. He then disappears and restores the ninja back to normal. The ninja arrive at the heart of the maze and find themselves outmatched by the Red Dragon, and appeal to Okino for help. Okino struggles with his decision but cannot in good conscience betray the ninja. He defies Unagami, his creator, and helps the ninja defeat the Red Dragon by revealing its weakness: a scale on its chest. The ninja defeat the dragon and Jay delivers the final blow. The Red Dragon changes colour and vanishes into an amulet. The ninja then continue their quest.
