Not long after Superwoman arrived, Owlman crossed over as well, bringing his bomb with him.
In his plan, Superwoman was there to draw attention.
All he had to do was find a place and quietly detonate the Quantum State Bomb, triggering a global catastrophe.
In truth, disasters that could affect humanity's fate were nothing more than insignificant natural changes to Earth itself.
For a planet, destroying it outright was indeed difficult.
That was why technology had developed toward planet-killing weapons.
Asgard's Bifrost, for example, was actually a planet-killing weapon.
Then there were things like the Two-Dimensional Foil used by advanced civilizations.
Those were even more terrifying.
For a Quantum State Bomb to destroy Earth, many conditions had to be met.
Owlman had calculated them precisely.
As long as it was detonated inside a massive active volcano, the Quantum State Bomb could destroy Earth.
So Owlman piloted a stealth fighter straight to Yellowstone National Park with the bomb.
Most of Yellowstone National Park lay in Wyoming, with portions extending into Montana and Idaho.
He then flew the stealth fighter directly toward the Rocky Mountains.
Yellowstone Volcano was one of the world's largest calderas. It was a supervolcano, and the largest supervolcano in the world that remained active today.
Its most recent major eruption had occurred roughly 640,000 years ago.
Therefore, to prevent this active volcano from erupting, the Yellowstone Volcano Observatory had been jointly established by the United States Geological Survey, the University of Utah, and Yellowstone National Park.
Scientists closely monitored its data every year.
Thus, this was not merely a tourist destination. Many areas were off-limits.
Owlman naturally knew that, so he did nothing after approaching.
Instead, he patiently waited until nightfall before making his move.
Like Batman, nighttime was Owlman's home ground.
Otherwise, he would not have worn
