Echo Echo

Echo Echo is the Omnitrix’s DNA sample of a Sonorosian, a race of living sound waves. He debuted in Alien Force, known for his ability to duplicate and use super-sonic powers for evasive fighting, swarming enemies, and executing signature moves like “Wall of Sound” or “Echo Chamber.” His evolved form, Ultimate Echo Echo, created by the Ultimatrix, is a more powerful transformation. It loses duplication but gains detachable sonic disks capable of firing significantly more powerful and deadly sonic bursts, making him one of Ben’s most formidable forms.
