Lord Decibel constructed his suit prior to the events of Ben 10.

In Don't Let the Bass Drop, he attacked a DJ Duster concert and threatened to destroy earth if he wasn't paid 1 billion dollars in 10 minutes. However, Ben and Gwen Tennyson were at the concert. Lord Decibel, expecting trouble, used his keyboard to deploy a sound barrier, but this was proven to be futile thanks to the knowledge of Gwen . Decibel was eventually defeated thanks to the combined efforts of Ben and his cousin.

In Speed of Sound, prior to the episode Lord Decibel convinced Helen Troy to build the Sonitrain.


Lord Decibel has a suit that acts as a form of communication to his victims when he uses his keyboard. However, alongside his keyboard, he has created numerous other devices that help him control sound to powerful degree. Powers gained by these machines include created sound waves powerful enough to generate deep fissures within the ground, erecting sound-based walls, and other such abilities.

His list of inventions includes:

  • The Sound and the Furry: A sound system mixed with a hovercraft, letting him unleash sound waves that could cause an avalanche, create a sonic shield, and hover in the air using soundwaves.
  • The Claws of the Cat: A much more powerful sound system that let him create a pair of snakes made out of sound.
  • Digital Quality: A portable sonic-based jetpack. This also came equipped with a device that let him hypnotically force people to dance using specific songs.
  • Speed of Sound: With help from Helen Troy, he created the Sonitrain, a locomotive that moves "beyond the sound barrier" using sonic technology. He was able to use this amplify his sonic powers, letting him charge his gauntlets with sonic energy to increase his punching power and unleash sonic projectiles. Later, he even developed the ability to transform sonic energy into the construct of a giant mech suit that he used as armor.
