- Zoids Concept Art: Modeler Spirit Series

    MSS was a decent line, but was over sooner than its time. There is still some concept art floating around that's worth mentioning.

- Concept Images

    These images were posted in Dengeki Hobby Magazine.

- Variation Concepts

    These images are actually from the OJR era and are quite old, but were brought back to life with the issuing of the MSS series. Each image was included in the instruction book of its respective Zoid.
