Is it hyper shadow or super shadow

It's Super Shadow. "Hyper Shadow" was a misprint, along with the confusion stemming from the fact that Super Shadow is a much lighter, almost white, shade of gold (lemon-chiffon) than Super Sonic. Hyper forms were only in Sonic the Hedgehog 3, and Sonic and Knuckles, and you needed the Seven Super Emeralds to acquire them. The Super Emeralds have yet to appear outside of the aforemented games, and nor have Hyper Forms.
