Echo is the secondary protagonist of the Disney XD series Mr. Young and Adam's love interest on the show.


She is a girl in Adam's ninth grade science class. It is unknown if she likes Adam back. She is very good friends with Adam, Ivy, Derby, and sometimes Slab.


She is thoughtful, socially aware, extremely gorgeous, and secretly likes all things to do with sci fi. She also enjoys fantasy roleplay. She is intelligent, and is sometimes described by Principal Tater as a show-off. She uses her quick-thinking to trick Ivy into doing real work by making some excuse related to a mall or shopping. She is also a bit gullible.

She is also an environmentalist, feminist and loves animals. She's also friendly, kind-hearted, hardworking, and responsible. But also a little devious, and occasionally does things which are at least morally questionable.


She has a pet hamster named Tickleschmootz, until Adam cloned it, after thinking he had killed, so now she has two identical hamsters.

In Mr. Pixel, when Adam finds pixel Echo, after he saves them from being deleted by Derby, pixel Echo reveals she likes Adam and leans for a kiss; unfortunately for Adam, Mrs. Byrne destroys the computer.

One of the only characters who is almost never shown cross-dressing.



Adam has a crush on Echo, but she is oblivious to this, but she seems to have a crush on him in some episodes. She is also enemies with Adam in some episodes.
