Walter Shriev was a villain in Batman Beyond who used a specially engineered sound suit to battle Batman as Shriek.

He is voiced by Chris Mulkey, who is best known as the corrupt Deputy Ward in First Blood and the silent alien host Jack DeVries in The Hidden.


Walter Shriev was a highly skilled audio engineer. He tried to find a more traditional line of work with Wayne-Powers using his sound technology, however, Derek Powers saw no profit in it and threatened to cut his funding. In order to save his business, Shriev created a suit of sound for demolition. Powers saw no real use of it, until he discovered it could be used to destroy more than blocks. In order to please Powers, Shriev agreed to assassinate Bruce Wayne. As a result, he became Shriek; a villain with sound based powers. Shriev is able to use sound vibrations to create earthquakes and other destructive properties. He's also able to "mute" all sound in a surrounding area. He also possesses the ability to transmit radio signals to receivers the size of a paperclip.

After his first encounter with Batman, Shriek's suit was damaged, which caused him to lose all sense of hearing. While he was eventually able to form a kind of hearing aid, he was never able to fully regain his hearing.

Shriek has made a cameo in Justice League Unlimited, being described as a sonic-sound blasting villain from Terry McGinnis’s early days as Batman who continues to wreak havoc in Gotham.

Powers and abilities[]

While Shriev had no powers by himself, he possessed a robotic suit that gave him a variety of sound based abilities. He could project sound at a strong enough frequency to destroy anything he aimed at as well as isolate and magnify any single sound while muting all others.

Shriev was a genius when it came to sound. All of the technology was of his own design. He was capable of doing amazing thing such as rigging a building to act as a massive tuning fork to disrupt air molecules throughout Gotham and make speech impossible, to something small scale like creating a tuning fork which created a vibration as addicting as any drug.
