Hawk & Dove
Hawk is one of the baddest looking customs I've ever done.  I built him on a Hawkman base, so he is huge and buff.  To build him, I first cut off the little wing stubs on Hawman's back with my Dremel.  Next, I removed his helmet wings with my X-acto and Dremel.  I also ground off his boots, beak, , belt, chest harness and emblem.  Using Sculpey, I filled in the two holes in the figure's back where the wing stubs were.  Next I painted the figure.  I cut out Hawk's wings and glued them on with Super glue.  Finally I sealed the figure with acrylic sealant.
I made Dove from a Flash base.  First I cut off Flash's ear wings with an X-acto.  Then I removed his belt, gloves and boot wings with my Dremel.  I added Doves nose with Sculpey.  I then primed and painted the figure.  My wife made Dove's cape.
