Eco Sonic speeding through the Shazamazon Rainforest

Eco Sonic is a variant of Sonic the Hedgehog's alternate super forms. He achieved this form while running at high speeds through the Great Rainforest while using Nate Morgan's Super Emerald to return Knothole to 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 Solar Sonic and Polar Sonic after becoming Ultra Sonic and traversing across all of Mobius.
