The Kaiju first appeared on August 10th, 2013 in San Francisco. The beginning of the incident was believed to be a 7.1 earthquake; however, a massive, three-hundred-foot creature, later known as « Trespasser, » eventually emerged from the San Francisco Bay and attacked the Golden Gate Bridge. After destroying the bridge, the creature proceeded towards San Francisco and caused significant devastation; it cut a three-mile-wide path of destruction through the city. The massive creature then went on a 35-mile rampage across the West Coast that lasted for six days. It continued on to Sacramento and Oakland, causing massive destruction in its attack. The United States and British militaries responded to the attack and battled the creature for six long days. Despite the use of troops, tanks, artillery and jets, the combined forces of the two armies failed to kill the massive beast. On August 15th, the military decided on using tactical nuclear missiles in the hopes of bringing down the creature. They finally succeeded with three tactical nuclear missiles. With the end of the destruction, three cities were left devastated and tens of thousands of people had died. The dead were mourned, the event was memorialized and humanity moved on. The incident in San Francisco was later known as « K-DAY ».
