Kaiju

Summary
There are four playable Kaiju currently (three in the base game, one as DLC). Other playable Kaiju are planned as expansion or DLC content, though no release dates have been discussed.

Size Increases
As your Kaiju trains new Abilities, they increase in size and power. These size increases happen after you complete training of your first Tier 3 ability and again after you complete training of your first Tier 5 ability.

Skins
Different Skins are available to change the look of your Kaiju. They can not be changed mid game, but only set when starting a new game. New Skins will be added for special events and as DLC.

Ginormasaurus
The Great Machine, Ginormasaurus (or Gino for short), was created by Dr. Norman E. Farious as the world's first mechanized Kaiju. It is dependent more on energy then the other four resources.

Shrubby
The Chlorophyll Creeper, Shrub-Ziggurath (or Shrubby for short), was created by Lillian Belladonna. Shrubby is a three-headed plant monster with powers and abilities derived from the field of Mad Botany. It is dependent more on Bio-Matter then the other four resources.

Armagordon
The Massive Mutant, The Atomic Superman, Armagordon (or Gordon for short), was created by Ivo Wyrdstrom. Armagordon is a Purpletonium-fueled super-mutant with powers and abilities derived from the field of genetic engineering. It is dependent on both energy and Bio-Matter.

Grey Goop
The Nanotech Nightmare, the Grey Goop was unleashed on the world by the mad scientist Dr. Malady Maleficarum. Composed of the Purpletonium-powered smart-matter dubbed the GOOP (gelatinous ordering omni-morphic polymatter), this Kaiju can shape shift into other Kaiju forms.
