While clad in his power armor, Ren appears as a tall figure clad in armor of bronze, copper and electrum. The detailed plates are covered in fine engravings and designs, lending aesthetics to the industrial design. He typically wears a hat and overcoat over the armor, further trying to soften its design. Occasionally, loud clouds of steam billow out from exhaust ports around the legs.

Out of his armor, a half-elf of average height is revealed. He has sun-kissed skin and bright red hair, carrying a bag with various smell tools on and inside of it over his shoulder.
