Magog was Alex Ross/DC's poke at EXTREEEEME Marvel character. He's literally Cable with gold armor and a helmet. Some people argue this fact to a fault. Well I took the new Magog DC Universe figure, modded a ML 6 cast Cable head from CamcoKid [link] swapped his feet for Judge Dredd's feet so he had ankle rockers, and a new left hand. Wham, bam, it's Cable man! Dunno where the guns came from but his Psi Spear was Magog's plus a new tip. Cable's eye is a little reflective gem that works really well! I've used them with some of my Transformers and Grimwing customs.
Exactly what I had in mind and you beat me to it, but I changed my mind because honestly Magog looks so cool.
