|Other Saotome Robots|
Three of the various other mechs built by Dr. Saotome
The Robots were all built in the past by Dr. Saotome and his staff before they were placed into the Saotome Institute's storage. Some of them however were presumably destroyed when hundreds of genetically modified Newts come raining down and invade the labs.
More were seen years later when Dr. Saotome went into his private room in the research center of the institute. When the influx of Getter Rays from below the institute started to go out of control, the prototypes started to move on their own and after the Getter Ray meltdown they were destroyed.
