Evolved Form/Devolved Form Ultimate Echo Echo

Echo Echo is a Sonorosian from the planet Sonorosia. In Ben 10: Negative Rising, he has a Nemetrix predator named Ampliscreech.


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 tinny, but became slightly lower.

In Omniverse, Echo Echo's eyes are now more line-like, and he 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.

In Ben 10: Protector of the Omniverse, he looks like his Omniverse appearance but with his Alien Force/Ultimate Alien eyes, his legs are less stubby and his Infinimatrix symbol is on his chest.

Echo Echo In POTO

In Ben 10: Heroics Unleashed, he looks like his Alien Force/Ultimate Alien appearance, but he wears black cuffs on his arms and black pants.

In Ben 10: Ultimate Omniverse, he has his Omniverse appearance, but his Omnitrix symbol is on his chest, and his headphones don't have black lines on them.

In Ben 10: The Omniwars, he has his Alien Force/Ultimate Alien appearance, but with stripes going down his headphones. His legs are somewhat skinnier. The Omnimatrix IV symbol is on his chest. Negative Echo Echo has cords that extend from his arms, his eyes are red, and he is taller. Kenny as Echo Echo has his Omniverse appearance, but with the Omnitrix on his lower stomach.

In Ben 10 - Infinity, his appearance has changed drastically. He retains his square head, but with circular eyes with two blue triangles coming from the top and bottom. He has a dome on his head with two wire coming from it, attaching to the omnitrix symbol, with two more going from there to his back. His hands are more similar to his ultimate form but with only a thumb, with a circle ontop with small lines going to the sides, down, and up to the head.

In Kenn 10: Omnistorm Echo Echo appears as both his Omnicerse appearance (for Ben's transformation,) and for Kennedy's own the trix is blue/gold themed, eyes are blue and all green parts are a blue colour just as The Omnitrix is.

In Legion Of Ultimate Superheroes, he has his Alien Force/Ultimate Alien appearance.

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 can.

By combining these two aspects, Echo Echo can create a "Wall of Sound", where 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 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 use echolocation, as seen in Alone Together.

Echo Echo can channel vibrations to enhance his screams, as seen in Undercover.

Echo Echo can transmit sound waves through speakers (such as phones), as seen in Grounded.

It has been shown that 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 in Prisoner Number 775 is Missing.

Echo Echo also found the ability to overload enemies with sound in Ben 10: Alien Armada. By biting enemies, sonic waves instantly flooded his enemies' ears and stunned them for 6 hours and/or melted their brains. Atomic Echo Echo and Cryo Echo Echo were also introduced.

Echo Echo is revealed to be immune to sound based attacks in John Smith 10, due to his headphones.


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.
