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 John Smith 10, he has his UAF appearance until Omniverse, where he has his Omniverse appearance.
In Jane Smith 10, she has the Omniverse appearance, with pink eyes instead.
