Jack was done observing. They were an interesting bunch. He'd give 'em that. They were about to be a dead bunch. Or maybe just a meal. Yeah. Option 2 sounds more delightful. Most had disappeared, so he decided to do something that would bring them all to him. He rose into the air, high into it. He needed something big.
Using every single energy power he'd obtained, his eyes began to rapidly glow quickly; red, orange, yellow, green, blue, purple, black, and white. He opened his mouth to reveal that it too, glowed these colors, and he shot a blast directly below him into the ground. The blast shot out with a sonic boom, and struck. A deep, thunderous, deafening explosive occurred, and the entire sky and ground were both lit up for mere moments.
In the aftermath, Jack hovered in the air. A massive crater below him, and every tree within a mile radius was simply gone. Barren land. Jack's perfect playing field. They wouldn't stand a chance.
He then immediately dropped, and crashed into his own crater, deepening it still, and giving another mini quake for his victims to suffer. He was going to savor
Every.
Last.
Drop.
Of their blood.
