Eco Sonic is an alternate form of Ultra Sonic. He has, so far, only appeared in .
Sonic the Hedgehog #71
He achieved this form while running at high speeds through the
Great Rainforest while using Nate Morgan's Super Emerald to return to Knothole in regular time. He has only achieved this transformation once (in #71), and it seems probable that the environment influenced his change to this state as well as Solar Sonic and Polar Sonic. Eco Sonic can manipulate plant life.
He is the only alternate form of Ultra Sonic who does not rhyme with the other forms.
