I've done several ROTF Megatrons, from repaints, to murder arm elbow mod and removable sculpted gimp arm hand part version with repaint, to the two non-transforming ones I recently did with the new arm, murder elbow, head mods, and repaint.
This is the one I did for myself, but I was unhappy with it being non-transforming so I took it back into the workshop.
I always wanted him to be more movie accurate, more articulated, and transformable, but without having to remove any parts to go to tank mode if possible.
By cutting away some inner back parts that aren't seen in either mode, and shaving down some of the shoulder and bottom of the murder arm, I did it!
I was a bit worried the larger new arm would hurt the look in tank mode, but I don't think it ended up being too bad since he is basically a mess of metal shards shaped sort of like a tank anyway.
I know its been done before in several ways so I'm sure not claiming any big breakthrough. Just glad I have a leader Megs I'm satisfied with putting on my movie figures shelf. Hope you guys like it too!
Added a simple lens flare effect to last bot mode pic's eyes since the lighting didn't catch the red painted eyes.
