The Metru Mantis is described as living across Metru Nui’s districts, but the only official image we have of one comes from the Rahi Book.
Could an argument be made that, similar to Fikou and some other Rahi, Metru Mantis have different color palettes based on the region the individual lives in? For example, would a subterranean Metru Mantis have a black body instead of a green one?
