Trespasser is the first Kaiju to emerge from the Breach and attack humanity. It attacked San Francisco on August 10, 2013[3], and over the course of six days, it destroyed three cities in a thirty-five mile long path of destruction, before it was finally killed by the United States military and British Royal Air Force.[1][2]


Trespasser was measured to be 302 feet tall (92 meters), and weigh 2780 tons.[4] Trespasser's hide was thick and protective, and could withstand almost any type of conventional weapon. Trespasser emits an orange bioluminous glow from inside its mouth.

Like Slattern, Knifehead, and Scunner, Trespasser's main arms are actually two fused arms, each ending with three clawed digits.


Trespasser's approach to the city is marked with a 7.1 earthquake, followed shortly by its rise from the water near the Golden Gate Bridge. 

It destroys the bridge and everything on it, proceeding to cut a massive path of destruction through San Francisco, Sacramento, Oakland and the numerous surrounding cities. Conventional weapons used by the US military, assisted by the Royal Air Force, did nothing to penetrate the hide of the creature.

The fight against Trespasser lasts for six days before the military would finally resort to using three tactical nuclear missiles to kill it.[7][8] The three missiles killed Trespasser, but at the expense of Oakland, much of the Bay Area, and all of those living there.


Shortly after its death, the military gathers its remains and put its skull on display for the public. Trespasser's attack is thought to be an anomaly by the general public; however, six months later, a second Kaiju emerges in Manila.[1]

Because Trespasser’s attack occurs before the formation of the Pan Pacific Defense Corps, when established, the Defense Corps is unable to determine its category class from its corpse after the creation of the Serizawa Scale.[9][note 1]

Once its remains are removed from the area, Oblivion Bay, a graveyard for destroyed Jaegers, is established in Oakland.[8]

  1. Travis Beacham: @Tekk999 They aren't sure about Trespasser. It was before the category system, and the nuke that killed it badly damaged its remains.
  2. Travis Beacham: Exactly right. Yep, it's name in the canon is Trespasser. "Axehead" was the look's nickname.
