Echo Echo

Echo Echo is a Sonorosian from the planet Sonorosia.

Appearance
Echo Echo is a small white alien whose body is a living amplifier. One of the most noticeable features is a square appendage resembling an MP3 player behind his back with the number 10 on it, that connects to his ears, that look like headphones. (It is possible that for the real species, the number changes to the clone's number when he duplicates himself, in order for them to keep track.)

Echo Echo can scream at ultrasonic frequencies capable of overloading machinery and stopping projectiles in mid-flight. He also has the ability to duplicate himself, not unlike Ditto, but different in that the clones aren't linked in any way, allowing entire groups to be knocked out without hampering the rest. Interestingly, his clones do not weaken with number. Their power stays the same. His cloning capabilities seem limitless.

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.
