How Do the Kaiju Return in Pacific Rim Uprising?

WARNING: The following article contains spoilers for director Steven S. DeKnight's Pacific Rim Uprising, in theaters now.

The original Pacific Rim was a thrilling slugfest between machine and monster. Due to a transdimensional breach that had opened at the bottom of the Pacific Ocean, enormous alien creatures called Kaiju were free to roam Earth and destroy everything in their path. After years of battling these monsters using their powerful Jaegers, humanity's fighters devised the ultimate plan to bring an end to the brutal war: The last remaining Jaegers traveled to the bottom of the ocean to seal the Breach.

Pilot Raleigh Becket (Charlie Hunnam) crossed over to the other side of the Breach, into the Kaiju home dimension, and detonated his Jaeger's nuclear core. He and his co-pilot Mako Mori (Rinko Kikuchi) made it back to Earth alive in their escape pods, and the Breach was sealed. However, in the sequel Pacific Rim Uprising, the Kaiju have returned. But how is that possible if the portal was close in the 2013 original?

Pacific Rim was a straightforward affair that plunged us headfirst into the final days of the great Kaiju War. What it lacked in story, it made up for in massive set pieces that elevated the film to the status of a cult favorite. However, Uprising plays things differently. As a matter of fact, for the better part of the film, the world is still at peace. But there is a also a bit of a mystery at play involving Shao Industries, and its planned activation of a worldwide fleet of automated Jaeger drones.

However, we come to learn that those drones are dangerous because they were partially designed using cloned Kaiju DNA. Worse still, they are actually piloted by cloned Kaiju secondary brains. When the fleet is fully activated, those drones morph into Kaiju-Jaeger hybrids, and they are quick to obey the will of their otherworldly masters, the Precursors. Combining the beams of their core reactors, the hybrids open new Breaches all along Earth's Pacific Rim. Because punching a hole into another dimension isn't exactly easy, it takes a bit of time for the energy to create new breaches.

The efforts of the humans are enough to shut down all of the hybrid drones before the breaches to the other side can be opened. Well ... almost. While the breaches are quickly closed, three Kaiju still managed to get through -- two category fours, and one category five. And three Kaiju are more than enough to destroy the world.

In theaters now, director Steven S. DeKnight’s Pacific Rim Uprising stars John Boyega, Rinko Kikuchi, Scott Eastwood, Cailee Spaeny, Jing Tian, Adria Arjona, Karan Brar, Ivanna Sakhno, Zhang Jin, Zhu Zhu, Burn Gorman and Charlie Day.
