Here we see a few members of the Rainbow Factory’s guards)staff, this is just a simple diagram of the common uniform apart from a labcoat. The shape of a spectra respirator can vary depending on individual head shape and size. These kinds of personnel fill out all sorts of roles, whether it be guard, worker, to operating machinery. For instance, they’re shown here wheeling off that old man to his doom, god knows what they’ll do to him.
