Category 3 Supporter-class Scientist-type
From Machina Main Cluster Official Wiki
The Category 3 Supporter-class Scientist-type is a common Supporter-class Machina, but is by no means basic. They are characterized by their equipment dedicated to the collection and analysis of human genetic material, or M2 Nanomachines and the Gene-Code within, in order to eventually create a 'package' of upgrades for their Queen. These Machina almost exclusively originate from human scientists. They differ from Supporter-class Succubus-type Machina in that they do not venture beyond their own Clusters to retrieve genetic samples.
