For my 200X He-Man, I used the King Greyskull buck, a He-man head, the electronic sword, and the vest/harness, shield, axe and belt emblem from a 2oox He-Man. The hair was a bit trickier, as I used pieces of He-man and King Greyskull's hair and glued them together. New paint apps were applied to the hair, belt, gauntlets and boots.
You did awesome!
