Supermike!

He's back! Mike Gordon, alias Supermike, reappears on the scene challenging Zagor to grant him a rematch... and to fight  again another seven new tests, believing that the outcome of the first race has been falsified. But this time, the Yellow Spirit is not alone... with him there are Nestor, a robust black servant, and a band of Indians who seem to have allied themselves with him pursuing a mysterious purpose.
