WALL... OF... SOUND!!!

– Echo Echo while using his sonic attacks.

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

Appearance

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]The headphones are attached to a backpack.

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

Echo Echo can scream at audible to ultrasonic frequencies capable of overloading machinery, shattering steel, stopping projectiles in mid-flight, destroying multiple Laser Lances at once if concentrated for enough time and even damaging Taydenite at the right frequency.[DJW 3]

Echo Echo has the ability to duplicate himself, but unlike Ditto, 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. Even if the clones are defeated, Echo Echo can be fine as long as at least one is still intact.

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, as demonstrated in his fights with Helen[4] and Ultimate Kevin.[5]

Echo Echo's sound holes help him resonate.[MW 1] He can also detect vibrations in the ground.

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 completely on his own,[11] and kick off the trunk door from the DX Mark 10 with one foot.[5]

With the help of multiple clones, Echo Echo can throw a Plumber Ship about a meter,[12] carry a Murk Gourmand,[13] and hold his own against larger opponents such as the dragon robot,[10] a Highbreed,[6] and Ultimate Kevin.[5]

Echo Echo also appears to be rather durable, as he and his clones were able to withstand being thrown against a wall.[10]

Echo Echo can levitate in the air.[14][15][DJW 4]

Echo Echo can create copies of any object he is holding while making clones.[16][GT 1][note 1]

When under the effects of a cold virus, Echo Echo can accidentally unleash sonic sneezes rather than intentional sonic screams.[17]

Weaknesses

Echo Echo clones are only durable to a certain extent, as they can be destroyed by Sunder's power axe,[18] an Aerophibian's neuroshock blasts, either a Methanosian or Pyronite's fire attacks, or a Cerebrocrustacean's electric attacks.[5]

Echo Echo can be rendered unconscious if hit by a quill from a member of Argit's species.[3]

Echo Echo can be immobilized by a Necrofriggian's ice breath.[5]

Echo Echo's sonic screams can easily hurt his teammates' ears.[10][19] However, technically speaking, they are not as powerful as a Loboan's sonic howls.[DR 1]

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

Echo Echo can be controlled by a Vladat via their Corrupturas.[DJW 6]

Etymology

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

Trivia

  • Like Rath and Atomix, Echo Echo gives names to his attacks and moves. The names of the attacks are notably less hammy than the former two. This trait is shared with Ultimate Echo Echo.
  • 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] It is unknown who came up with the latter concept, as Derrick J. Wyatt heard it from someone else.[DJW 7]
    • Echo Echo and NRG are the only aliens whose appearance are actually containment suits.
  • 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 8]
  • Echo Echo's singing sounds like auto-tune, though he is really good at dubstep.[DJW 9]
  • 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.[merch 1]
  • Dee Bradley Baker did Echo Echo's voice by talking while inhaling and squinching his upper throat shut.[DBB 1][DBB 2]
  • Echo Echo originally had the ability to extend his neck and arms in the pre-production stage of Alien Force.[GM 1]
  • 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 was supposed to retain the Omnitrix symbol on his chest in the pre-production stage of Omniverse.[DJW 10]
  • Echo Echo was Dwayne McDuffie's favorite Omnitrix alien.[DM 3]
  • From Arc 4 of Omniverse onwards, Echo Echo is replaced with Juryrigg in the opening intro of the show.
  • Had Negative Echo Echo appeared in Omniverse, he would have been either a red recolor of Echo Echo's appearance in said series or at least have some red markings.[DJW 11]
    • Derrick eventually drew a version of Negative Echo Echo in the Omniverse art style in 2020.[DJW 12]
  • 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).

Notes

  1. According to Derrick J. Wyatt, Echo Echo's object duplication was due to a glitch in the original Ultimatrix. This ability was removed from Echo Echo's DNA when Ben acquired the new Omnitrix in The Ultimate Enemy: Part 2.[DJW 5] However, it is unknown if this is canon as Matt Wayne seemed to be unaware of the existence of glitch powers.[MW 2]
