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


Because his true form is made of living sound waves,[DJW 1] Echo Echo's appearance is actually a small, white containment suit[DJW 2] made of silicon,[1][2] making his body a living amplifier.

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. The green circle-shaped indents on the back of Echo Echo's hands are sound holes,[MW 1] and the inside of his mouth is also green with lines that give it the appearance of an amplifier. He also wears headphones so he would not be hurt by his own sonic screams.[DM 1]

In Alien Force and Ultimate Alien, Echo Echo wore the original Omnitrix/Ultimatrix symbol on his chest.

In Heroes United, Echo Echo looked mostly the same as before, except his eyes were bigger and his mouth was recolored black.

In Omniverse, Echo Echo's eyes bulge out, he has two black stripes on both of his earplugs, which are more pronounced, his legs are stubby, he now has three toes, and the green circles on his hands are now bigger. He is also shorter and has a circular shape on his stomach and the tapes on his legs are now gone. His head is less round and is wider and the outlines of his mouth and eyes are thicker as well as his wires. He wears the Omnitrix symbol on his forehead.

Powers and Abilities

  • Self Duplication
  • Sonic Screams
  • Sonic Force Fields
  • Enhanced Strength
  • Enhanced Jumping
  • Wall of Sound
  • Echo Chamber
  • Echolocation
  • Levitation (via Glitch)
  • Object Duplication (via Glitch)

Echo Echo can scream at audible to ultrasonic frequencies capable of overloading machinery, shattering steel and stopping projectiles in mid-flight.

Echo Echo has the ability to duplicate himself, much like Ditto, but it is different in the sense that the clones are not linked to each other in any way, allowing entire groups to be knocked out without harming the rest and he can clone himself much faster than Ditto could.

By combining these two aspects, Echo Echo can create a wall of sound, where he and his clones can redirect projectiles back to their source by bouncing them off of strategically placed clones, as seen during his battle with Argit.[3]

Echo Echo can create an echo chamber, where his clones attack from all directions and keep screaming until the target is knocked out or defeated; this is demonstrated in his fights with Helen[4] and Ultimate Kevin.[5]

Echo Echo can detect vibrations in the ground.

Echo Echo's sound holes help him resonate.

Using his sonic screams, Echo Echo can locate objects/people, giving him the ability of echolocation.[6]

Echo Echo can channel vibrations to enhance his screams, as seen when he touched Kevin, who had absorbed metal that caused him to vibrate when struck by Gwen's Mana.[7]

Echo Echo can transmit sound waves through speakers, such as phones.[8]

Echo Echo can use his sonic screams to create a force field.[9]

Echo Echo is quite agile, as he is capable of jumping exceptionally high.[10][3]

Echo Echo seems to have more strength than his size suggests, as he can carry a power coupling ok his own,[11] kick off the trunk door from the DX Mark 10 with one foot,[5] throw a Plumber Ship about a meter with the help of nine clones,[12] and carry a Murk Gourmand with the help of two clones.[13]

Echo Echo used to have the abilities of levitation[14] and creating copies of any object he was holding while making clones[15] due to a glitch in the original Ultimatrix. Both of these abilities were removed from Echo Echo's DNA when Ben acquired the new Omnitrix in The Ultimate Enemy: Part 2.[DJW 3][DJW 4]


Echo Echo has a fragile body that can easily be destroyed in battle, as shown when Ultimate Kevin destroyed several Echo Echo clones with Jetray's neuroshock blasts.[5]

Echo Echo's sonic screams can easily hurt his teammates' ears.[10][16]

Echo Echo has a limit to the number of duplicates he can make, which depends on the amount of energy he has access to.[DM 2]

An echo is the reflection of a sound that arrives at a listener with a delay after the direct sound, referencing his audio-kinetic powers. The repetition of "Echo" in his name references both the nature of an echo and his self-duplication power.


  • Echo Echo had concept art drawn and his final design created by Glen Murakami, with color styling by Chris Hooten.[GW 1]
  • Echo Echo's design was based on an Apple iPod.[GW 1]
  • Echo Echo originally had the ability to extend his neck and arms in the pre-production stage of Alien Force.[GM 1]
  • Echo Echo was supposed to retain the Omnitrix symbol on his chest in the pre-production stage of Omniverse.[DJW 5]
  • If Ben were to use Echo Echo with Skurd attached to the Omnitrix, Echo Echo's clones would have to remain huddled to use Skurd's power.[DJW 6]
  • Echo Echo's voice has changed throughout his appearances in the franchise:
    • In Ben 10 Returns: Part 2 and Kevin's Big Score, it originally sounded very high-pitched and tinny, and had a strong robotic filter.
    • In Alone Together, it became higher-pitched, and the robotic filter was less prevalent.
    • From Good Copy, Bad Copy until his final appearance in Ultimate Alien (Inspector 13; excluding Undercover), the robotic filter was missing.
    • In Undercover, it sounded like it did in Alone Together, but slightly deeper.
    • In Omniverse, it is high-pitched and more robotic, and it echoes more, akin to speaking through a portable microphone.
    • At some point in early production of Alien Force, Echo Echo's voice was supposed to sound like his most frequently-used voice in the series, but with an echo effect.[17]
  • Echo Echo was Dwayne McDuffie's favorite Omnitrix alien.[DM 3]
  • Like Rath and Atomix, Echo Echo gives names to his attacks and moves.
  • Originally, Echo Echo was a robot-like alien.[DM 2] This was later changed in Omniverse, as he is actually living sound waves wearing a containment suit.[DJW 1][DJW 2]
    • Echo Echo, NRG, and Feedback are the only aliens whose appearance is actually a containment suit.
  • From Arc 4 of Omniverse onwards, Echo Echo is replaced with Juryrigg in the opening intro of the show.
  • In FusionFall, there is a fusion of Echo Echo that, when defeated, releases Forever Ninja sets.
  • Echo Echo is similar in some ways to Echoes, the Stand of Koichi Hirose in Part 4 of the manga and anime series Jojo's Bizarre Adventure.
    • Both Echo Echo and Echoes ACT 3 are short, white humanoids with green as a secondary color.
    • Echoes (specifically ACT 1 and ACT 2) and Echo Echo are able to unleash powerful sound attacks from multiple angles simultaneously (Echo Echo via his duplication, and Echoes through writing onomatopoeia on surfaces).
