I've had a powermaster prime head for a while sitting on my shelf, its been goading me, egging me on to build something out of it, like a voice in my mind it haunted my dreams....er No....ok so maybe thats a bit over the top, but I had it sitting there waiting for the right parts to turn up for a custom.
Anyway I found a ninja frog zord at a junk store for 50p and thought that will do for the legs of a masteriece scale figure, then I scratch built the rest from junk parts,random robot fodder, bionicle and random plastic pieces. I basically made it up as I went along, but it took a shape that started to look more like a MUNKEY NOT TRUK, blasphemy to the G1 era fans. As a plus most of the colour scheme was more primal than prime, so very little painting on major parts means less chipping...... bonus!
the gorrilla head came from a knock off king kong, whos body was used for my next custom, and he has an openable chest with the matrix and some circuits.
here he is in all his glory with masterpiece prime for scale in one picture, enjoy.
