From Cybertron Galvatron:
I recasted the MP Hot Rod head:
Its almost the same scale & the good thing was it got a neck to make the articulation better than the original head. The ball joint was taken from a loose Lego Bionicle.
The next step is to repaint the whole figure to be a Hot Rod figure. The concept was taken from the other customizer I saw from the other site but the head concept was mine. Will update this post as I progress.
