Head/Helmet/Cowl: Comic Pack Serpentor
Torso: Spy Troops Overkill
Arms/Legs/Waist: Pit Viper
Cloak: MLS Magneto
Sword: Good To Go Customs

I had already done a Devil's Due version of Serpentor. But with all my current customising activity doing original Joes and Cobras I decided I wanted a version 1 Serpentor.
I cheated a little using a comic pack head, helmet and cowl. I used the same style Spy Troops Overkill torso that I used with my original Serpentor.
For the colour scheme, I went very close to the image from Issue 51 of the Marvel run.
