Echo Echo

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

Appearance
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. He has circle-shaped indents on the back of his hands which are green. The inside of his mouth is green with lines that give it the appearance of an amplifier. His voice originally sounded very high-pitched and tinny, but became slightly lower.

In Heroes United, Echo Echo's eyes are bigger and his mouth is black in color.

In Omniverse, Echo Echo's eyes bulge out. He has two black stripes on both of his ear plugs, which are more pronounced. His legs are stubby and 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. The tapes on his legs are now gone. His head is less round and is wider. The outlines of his mouth and eyes are thicker. His wires are also thicker. 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
Echo Echo can scream at audible to ultrasonic frequencies capable of overloading machinery and stopping projectiles in mid-flight.

Echo Echo has the ability to duplicate himself, like Ditto, but different in that the clones aren't linked in any way, allowing entire groups to be knocked out without harming the rest and he can clone himself much faster than Ditto could in the original series.

By combining these two aspects, Echo Echo can create a wall of sound, where the Echo Echos can redirect projectiles back to their source by bouncing them off of strategically placed Echo Echos.

Echo Echo can create an echo chamber, where the Echo Echos attack from all directions and keep screaming until the target is knocked out or defeated.

Echo Echo can detect vibrations in the ground.

Using his sonic screams, Echo Echo can locate objects/people (echolocation).

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

Echo Echo can transmit sound waves through speakers (such as phones),

Echo Echo can use his sonic screams to create a forcefield.

Echo Echo is quite agile, shown from his ability to jump quite high.

Echo Echo seems to have more strength than his size suggests, as he can kick off the trunk door from Ben's car with one foot and Echo Echo is able to throw (about a meter) a Plumber Ship with nine Echo Echos.

Weaknesses
Echo Echo has a fragile body which can be destroyed easily in battle, as shown when Ultimate Kevin destroyed several Echo Echos with Jetray's neuroshock blasts.

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