Notes
Marendar was biomechanical. It was somewhat bigger but not much bigger than a Toa or Glatorian.4
Greg's image of how Marendar eliminated Toa was that it could adapt to and resist Toa powers, with its own specialized weaponry to take Toa out.5
Even though Mata Nui gave Ackar, Kiina, Gresh, etc. elemental powers and named them honorary Toa, Marendar would not see them as Toa.6
