Ultra Sonic

Ultra Sonic is a transformation of Sonic the Hedgehog, when getting 7 Other Emeralds.

History
When Ixis Naugus raided Nate Morgan's secret tundra lab, he, as well as Sonic and Tails were infused with energies from a large cache of Power Rings. Though Ultra Sonic managed to hold his own against Naugus' attacks through manipulating the elements at the atomic level and with Hyper Tails, Ultra Naugus seemingly had greater stamina than either and waited for their transcended states to burn out before he attacked Morgan. After Nate sent Naugus back to the Zone of Silence, the two heroes found their Power Ring induced energies depleted, causing them to turn back to normal and in a weakened state. Upon being awakened, they had no memory of their advanced transformations until Nate told them of it.
