I was just looking up g1 prototypes, yknow, as you do, when I came across:
Tahu Mistika used to be blue!? I wonder which Gali would've been weirder; this, or the one we got.
Goes to show how little the designers of Mistika cared about the Toa's previous forms. They just coloured their Gali red and called it Tahu. At least the phantoka had some similar elements to the earlier ones.
