Echo Echo is the Omnitrix's DNA sample of a Sonorosian from the planet Sonorosia.

He was voiced by Dee Bradley Baker who also voiced Diamondhead, Chromastone, Big Chill, Wildmutt, Swampfire, Humungousaur, Jetray, Spidermonkey, NRG, Armodrillo, Water Hazard and Four Arms in the same franchise and Rex in Star Wars: The Clone Wars and Star Wars Rebels.


Echo Echo is a small white alien whose body is a living amplifier. He is actually living sonic waves contained in a suit made of silicon. One of his most noticeable features is a square appendage resembling an MP3 player behind his back with a port on it - decorated with a 10 symbol and what looks like cassette tapes on his lower legs. His voice originally sounded very high-pitched and tiny, but became slightly lower.

In Omniverse, Echo Echo's eyes are now more line-like and now has two black stripes on both of his ear plugs. His legs are also a little bit more stubby and the green circle on his hand is now bigger, covering most of his hand. He is also shorter and has a hexagonal shape on his stomach. The tapes on his legs are now gone. His voice sounds more robotic now, and it echoes more, as if he is speaking through a portable microphone.

Echo Echo wore the Omnitrix/Ultimatrix symbol on his chest in Alien Force and Ultimate Alien, and wears the Omnitrix symbol on his forehead in Omniverse.

Powers and Abilities

  • Duplication: Echo Echo can create an entire army of himself in seconds.
    • Duplication of Ben: By timing out with multiple clones still active, Echo Echo can create multiple Bens; each with their own Omnitrix. Though this is a rarely used technique as it splits up Ben's emotions rendering Ben less effective.
    • Object Duplication: Echo Echo can also duplicate items he is holding.
  • Enhanced Strength: Echo Echo possesses strength to a certain extent as 9 copies of himself were able to lift a large Plumbers ship.
  • Sound Manipulation: Echo Echo's body is entirely composed of sound waves and as such he can manipulate sound to a certain extent.
    • Sonic Scream: Echo Echo can unleash a sonic scream to disorient his opponents. These screams can be so powerful that they indirectly caused an aquarium with reinforced glass to shatter.
      • Wall of Sound: A technique Echo Echo utilizes which involves several to stand in a line before unleashing their sonic screams at the same time.
      • Echolocation: By manipulating his sonic screams, Echo Echo can use echolocation as shown when he used it to find a teleporter pad.
      • Echo Chamber: A technique which involves Echo Echo (using duplication) completely surrounding his opponent and unleashing multiple sonic screams all at once. This technique was used to render Helen Wheels (XLR8's species) completely unconscious.
      • Force-Field Generation: Echo Echo can manipulate his sonic screams to create force fields.
  • Enhanced Speed: Echo Echo was able to outrun a DNAlien while carrying a device just as big as he was.
  • Enhanced Agility: Echo Echo was easily able to dodge Thunderpig's mace.
  • Enhanced Stamina: Echo Echo's advanced musculature is considerably more efficient. As a result, his muscles produce practically no fatigue toxins during physical activity. His virtually inexhaustible stamina enables him to exert himself at peak capacity for an undefined period of time without tiring at all.
