The guardians are a team or warriors that are similar to the toa but have a lot less elemental power and instead rely on skill to get the job done. These are probably the same race/species as the skull villains, being simular in size and not toas.
Koiwa, Guardian of ice:
Alt version:
The alt is more akin to his original design:

Demus, guardian of jungle:
The wings are able to come off pretty easily and attach like the creatures.
Xeous, guardian of earth:
The sword is just invade fists and diplomacy doesn’t work.
Rotus, guardian of fire:
Probably the most simple of them, but I do like the swords.
Unnamed guardian of water and stone:
I’ve shown these before, just minor updates on them, but I do need help on names for them.
Please feel free to critic and such.
