S1E2 Stake Victory on the Moonlight

The android, powered by solar energy, must face a dangerous battle under the cover of night. With no sunlight to fuel his systems, he relies on his internal reserves and quick thinking to survive. Under the cold glow of the moon, he confronts enemies who have chosen the perfect moment to strike. Each move drains his limited power, forcing him to adapt and fight smarter. It’s a race against time before his energy runs out completely.
