Echo Echo is the Omnitrix's DNA sample of a Sonorosian from Sonorosia in Earth-1010.

His evolved form is Ultimate Echo Echo.


Echo Echo is a small, white humanoid, resembling a living amplifier. He is actually a being made out of sound waves encased in a containment suit. His most interesting features are a square appendage on his back resembling an MP3 player, with "10" inscribed, and the cassette-tape structures on his legs. He has two green circular indents, one on the back of each hand. The inside of his mouth is coloured green with lines that resemble an amplifier.

Echo Echo wears the Omnitrix symbol on his chest.

Powers and Abilities

Echo Echo can emit audible and ultrasound sonic screams, that can disable machinery and deflect projectiles.

Echo Echo can duplicate to a seemingly infinite capacity. The duplicates are completely independent and not connected in any way, allowing entire armies to form.

Echo Echo has devised a move called "Echo Chamber", where several Echo Echos surround an enemy and fire sonic screams continuously, until they are defeated or knocked unconscious.

Echo Echo can create a "Wall of Sound", where Echo Echos are placed strategically to deflect projectiles.

Another one of his techniques, demonstrated in Chapter 17, is Ultra Sound. It is a deafening shriek designed to inflict pain rather than cause direct damage.

Echo Echo can utilise his sonic screams for echolocation and to form forcefields.

Echo Echo can channel his sonic screams through speakers and amplify them using vibrations.

Echo Echo is surprisingly strong for his size, with just nine Echo Echos able to carry briefly an object as large as a Plumber Ship.

Echo Echo possesses great agility, judging by his ability to jump very high.


Echo Echo's containment suit is not particularly durable and can be destroyed easily in a battle.


Death of Ben 10

In Chapter 11, Ultimate Ben 10 briefly transforms into Echo Echo, before turning ultimate.

Ben Prime used Echo Echo briefly in Chapter 17 to fend off Apollo.
