Worker Zaku is a mobile suit from Mobile Suit Variations (MSV), a side-material line expanding the Mobile Suit Gundam universe. It is a non-combat industrial variant of the Zaku, adapted for construction, maintenance, and other labor tasks rather than battlefield use. The design reflects the Zeon reliance on mobile suit technology even in civilian and support roles. As a background machine rather than a character in the story, it helps illustrate the broader world-building and everyday applications of mobile suit engineering.
