The fits on the leg armor parts are also compatible with the hands of a regular Traveler. Flipping the chest armor upside down and seating it sideways around the head also pushes the heavy bio armored look.
Back in the 90's I was nuts about a figure called Battleclad Spawn from McFarlane Toys. The Skeleden Armor design owes that old character a debt of gratitude, as it was a definite influence on the stacked armor style you see in the pic shown above.
It turns out sculpting ace Eric Treadaway of the 4H was the man behind Battleclad Spawn, which is pretty neat, as Eric and I would eventually go on to become good friends as we worked on the 4H's OSM and Power Lords projects together.
