After Mutavore comes through the Inter dimensional breach, it heads straight for the city of Sydney, Australia. The creature proceeds to destroy two Jaeger's gaurding the city before easily breaking through the military's giant anti-Kaiju wall, before begining it's assult on the city. Mutavore manages to destroy most of the city's buildings before being interceptd by Australian made Jaeger, Striker Eureka. The two giants then engage each other in combat, despite the battle being close, Mutavore is finally defeated when Striker fires it's chest missiles, which strike mutavore in the torso and head, killing it almost instantly.

Mutavore's attack on Sydney ultimatley proved that the Military's anti-Kaiju wall would not be the answer causing them to re-activate the Jaeger program.
