“You’re in a decommissioned nuclear reactor. This whole chamber was designed to contain energies like yours. You could spend the next six—”

The doctor paused. “Sorry?”
Zzzap moved his head to the left, then to the right. “This is a fission reactor,” he said. “In this state, I’m a whole different scale of magnitude. Thousands of times more powerful. It’s like saying a pair of sunglasses can protect you from the visible light output of a hydrogen bomb.”
“I stand corrected,” said Sorensen. “As I was—”
“I mean, I could just let ’er rip and burn a hole straight up and out.””
