Tribulation

Tribulation is a Category VI Kaiju that was one of the three Kaiju that ravaged Sydney during the Shadow Basin Raid. The Kaiju assisted a Category V Kaiju known as Void Reaver in destroying Shadow Basin in Australia. After having ravaged the base, the two Kaiju then guarded Shadow Basin before the Kaiju known as Annihilus arrived and released Tribulation from the Precursor Hivemind. 
Tribulation's whereabouts and vitals are currently unknown... the last known sighting was outside of Shadow Basin prior to Konungr's arrival.
