Exterior Guardians

The exterior guardians are incredibly powerful toa-like beings whos purpose was to protect the Matoran Universe from exterior threats such as hostile alien races.

Deployment
Thousands of pods like giant toa canisters were attached at various points on the exterior shell of the Great Spirit Robot. If hostile craft or lifeforms began attacking the exterior, senors would activate the transport pods which would then be fired into the hostile craft to deploy the guardians.

Appearance
All Guardians are roughly 10 ft tall (a few feet taller than the average toa) with more heavy armour. Colours vary depending on powers but apart from that they look similar to toa. They appear to be wearing masks but it is in fact just that their breathing helmets are stylized to resemble masks.

Powers and abilities.
All Guardians can easily survive the cold of space as well as the zero pressure and and zero oxygen that would kill most MU beings within a few seconds. They also have enormous strength and the ability to move around in space with bursts of elemental energy.

Each Guardian possesses two or more powers (some of which are similar to MU elemental powers and mask powers). There is great variety in the powers of Guardians so that different ones can be deployed to deal with different kinds of threats.

The colour of armour on a Guardian corresponds to its powers (similar to Rahkshi):
