The Mel'roc Power Armor

Origin
The Talus branch of the UIDCC, or rather T-BM Davis felt that the construction of the UIDCC Saviant was progressing too slowly, so to assist with the construction they commissioned that a fleet of kinetically powered suits of armor, which they refered to as Mel'rocs (Meaning "gatherer" or "scavenger" in Zarithian Talus), soon after the completion of the fleet of Mel'rocs the UIDCC Saviant was seemingly built overnight.

Purpose
Originally, they were created to assist in the gathering of resources and construction of shelters in uninhabitable places. But soon after the initial attack on Zarith the Mel'roc design was modified by the Human branch of the UIDCC to create the Proto-Beetle Power Armor, and eventually modifed the Proto-Beetle to create the Beetle, Mantas, and Dragonfly Power Armors.
