Zortron compared to Saturn-Bit
Saturn-Bit on the left Zortron on the right
The most obvious difference between Zortron and Saturn-Bit is the lack of the die-cast armor plate causing Zortron to have a smooth painted chest piece. Also, Zortron has painted red crescents on his hips and painted "POLICE" on his shoulder dishes instead of decals which results in bolder colors against the dark background.
As shown above, the mold was modified to cover the old integrated copyright and production information with a panted version on a raised rectangle.
Discrusher on the left Roto Thrasher on the right
The weapon, as shown below, lost all of the vent details along the top and the silver at the bottom of the two claws. The base for the saw blade is now cast in black with painted silver details instead of the other way around.
