Following on from my last post, drawing from the ideas kindly put to me, I have a plan of how to go about making the Dark Invader*.
(* This pun is bad, even by newspaper standards. Please, someone come up with a better one!)
Body and arms from a Spartan Games 'Teutonic Knight Specialist', which I will re-pose to make more 'hulking';
Helmet from a Dreamforge Games Eisenkern Stormtrooper;
Then for the 'Arc - Sabre', either an Armourcast Cinematic *thingy* or a large Games Workshop Power Sword, converted to replace the barrel/blade on the Teutonic Knight.
What do you think? - I'd be most interested to know.
