One stormy night, dark clouds gathered over Brightstone City. Thunder rolled across the sky and lightning flashed between the buildings. Rain began to fall heavily, and the streets slowly became quiet.
But suddenly, the ground shook.
At the city's power station, giant electric robots crashed through the gates. Their metal feet smashed the concrete, and sparks flew everywhere. Alarms began to ring loudly.
Inside the control room, workers panicked.
"Something is attacking the power station!" one of them shouted.
"Shut down the systems!" another yelled.
But it was too late.
Standing outside in the rain was Dr. Voltaris, the dangerous scientist who wanted control of electricity. He wore a long black coat and held a glowing device in his hand.
"Tonight," he said with a cold smile, "Brightstone City will finally belong to me."
He pressed a button.
The robots moved forward, tearing cables from the ground and destroying the power generators. Lights across the city flickered and then went out.
Within minutes, the entire city was in darkness.
