The Breach (also known as the Portal) is a fissure[1] located off the coastline of China near Guam[2] on the floor of Challenger Deep in the Pacific Ocean. It connects the Earth to the Anteverse, the homeworld of the Precursors and the Kaiju.[3][note 1]


The Breach is said to be atomic in nature. It uses energy stemming from the activity in the Earth's tectonic plates to maintain a stable connection to allow Kaiju to pass through its "throat".[4] The Breach folds space-time to close the extreme distance between two points; the energy required to maintain that connection, however, makes the Breach itself vulnerable to attack.[4]

The electromagnetic signatures given off from its physical structure suggests that the dispersal of energy greater than its own would destabilize the Breach and destroy it, sealing Earth off from the Anteverse. Courtesy of Newt's and Hermann's experiments, it is later revealed that only a Kaiju can leave or enter the Breach.[4]

The inside of the Breach is purple and blue, and is lined with organic circuitry and pulsing with electromagnetic energy. At the bottom end of the Breach are several sphincter-like gateways that lead to the Anteverse.


Gipsy Danger and Striker Eureka prepare to assault the Breach.

On August 10, 2013[5], the Breach was opened on the floor of Challenger Deep in the Mariana Trench between two tectonic plates.[4][1][6] Upon opening, Kaiju began to move through the portal towards various cities located on the Pacific Rim.

In conjunction with fighting the Kaiju with Jaegers, the Pan Pacific Defense Corps attempted to use conventional weapons against the Breach. Their efforts proved unable to penetrate the Breach itself, continually bouncing off the portal onto the ocean floor.[1]

Operation Pitfall

On January 12, 2025, the Jaegers Gipsy Danger and Striker Eureka assaulted the Breach directly and were ambushed by Raiju, Scunner and Slattern. Despite the fact that they were outnumbered 3-2, Gipsy Danger and Striker Eureka ultimately prevailed against the Kaiju and were able to successfully destroy the Breach as planned, albeit at the cost of both Jaegers and the lives of Striker Eureka's pilots.[1]
