Silver grey insert. Unlike the Duncan Super Hero Magic Motion series, this Super Hero series used static images on both sides of the yo-yo. The profile of this yo-yo is identical to the Duncan Professional.
On one side is the bust image of Hulk with "The Incredible Hulk" in white lettering and "Duncan Yo-Yo" below that in black lettering below his head; the opposite side shows the full character charging and the same lettering but to the character's left side.
The metal axles on Duncan Super Hero series yo-yos were Reslon coated. Some people refer to the coating as Teflon, but that is incorrect. Reslon was Duncan's own thermal bonded fluorocarbon resin coating that reduced friction between the axle and string, and allowed up to 20% longer spin times. Reslon axles were also used on Duncan Imperials in the early 1980s. The Reslon trademark, owned by Flambeau, was officially registered August 28, 1979. On December 15, 2000 the trademark was cancelled.
Original, unopened boxes of this model of yo-yo still have the very long single piece of tape that sealed down both sides of the box top flap, and the bottom.
