Solar Sonic is an alternate form of Ultra Sonic.
He can achieve this form while running at high speeds through the Great Desert near Sand Blast City while also using Nate Morgan's Super Emerald to return to Knothole in regular time. He has only made this transformation once, and it seems probable that the environment influenced his change to this state as well as Polar Sonic and Eco Sonic. Solar Sonic can manipulate fire.
- He has, so far, only appeared in Archie Sonic the Hedgehog Issue 71.
