Echo Echo is the Omnitrix's DNA sample of a SonorosianInspector 13Inspector #13 from the planet Sonorosia.
==Appearance==
Echo Echo is a small, white humanoid made of silicon.Gwen TennysonFool's Gold His body is natural; although he strongly resembles a robot, he is neither it nor an animated containment suit. 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 which help him resonate, 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. The headphones are attached to the appendage on his back.
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.

==Naming and Translations==
==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.
*In FusionFall, there is a fusion of Echo Echo that, when defeated, releases Red Knight sets.
*Duncan Rouleau once stated that Blitzwolfer's sonic howls are more powerful than Echo Echo's sonic screams. He later did not recall making the original statement, elaborating that the answer to the question depends on what the story needs.
*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.
*Echo Echo's singing sounds like auto-tune, though he is really good at dubstep.
*Dee Bradley Baker did Echo Echo's voice by talking while inhaling and squinching his upper throat shut.
*Echo Echo was originally named Echo.
*Echo Echo originally had the ability to extend his neck and arms in the pre-production stage of Alien Force.
*Echo Echo had concept art drawn by Eric Canete and Glen Murakami, with his final design created by Glen, with color styling by Chris Hooten.
**Echo Echo's design was approved rather quickly.
*Echo Echo's design was based on an Apple iPod.
*Echo Echo was supposed to retain the Omnitrix symbol on his chest in the pre-production stage of Omniverse.
*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.
**Derrick eventually drew a version of Negative Echo Echo in the Omniverse art style in 2020.
*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).
*Echo Echo was Dwayne McDuffie's favorite Omnitrix alien.
*Derrick preferred Echo Echo to Ultimate Echo Echo.
*When asked if Echo Echo could levitate, Derrick considered it a mistake with his powers.
