Cacophonous Conch

The Cacophonous Conch is an object that appears in the Sonic the Hedgehog comic series published by IDW Publishing. It is an ancient conch shell that acts as a natural inhibitor to Zeti powers.

Description
As implied by its name, the Cacophonic Conch closely resembles a real-life musical instrument conch. It is very long, with long pointy spikes on the outer surface and is colored dark purple. Also, its opening glows red.

When blown into, the Cacophonic Conch glows red and gives off a low-pitched sound, which allows the user to inhibit the powers of nearby Zeti, including their ability to manipulate magnetic fields.

Past
At some point in the recent past, Dr. Eggman somehow obtained a Cacophonous Conch, which he used to subjugate the Deadly Six during his time on Lost Hex. However, Sonic soon arrived and inadvertently freed the Deadly Six, causing them to turn against Dr. Eggman and take control of his Badniks.

The Last Minute
While planning to recruit the Deadly Six to help him control the Zombots, Dr. Starline used the Warp Topaz to retrieve a Cacophonous Conch.

Trivia
