Kaiceph emerges from the Breach June 1, 2014 and attacks Cabo San Lucas. The military's attempts to lure the creature away from the city fail. They are forced to attack the Kaiju with a nuclear strike that kills it at the expense of half the city's inhabitable areas. Its remains are removed from the city and relocated onto an aircraft carrier.
During the September 15, 2014 South Korea conference, Kaiceph is shown on a projector during Stacker Pentecost's speech.
