This is the second Deadpool I've made (First time posting here though), but I have to say this is my favorite one so far of all my customs.
I've always wanted a Deadpool with a ready to rumble looks, with muscular arms and legs (but not too much),which is why I used DC figure as the base.

Parts:

This figure was made from several parts of an action figures in my collection,
Head was Moon Knight re sculpted,
Torso and waist part was long haired Superman,
Arms were a combination of Marvel legends and DC figure I don't know about.
Hand were from X-men Cyclop, old hands and wrist were chopped off, for a better articulation.
Neck strap was sculpted.
Legs Could not remember
Feet were too replaced, to Marvel legends Wonderman
Pouches are cut from Marauder's belt
Swords are from Hasbro's Deadpool
Belt buckle was hand sculpted, took me very long time.
Straps is made off leather.
Repainted the whole thing in red and black !
