Wavelength is initially credited as a hurricane contained in a clear glass bottle shaped like a human. A cork adorns the top in place of hair. Black goggles are attached to his face and act like eyes, morphing with facial expressions. His right "eye" is slightly larger than the other. A comically large and dark mustache covers lips (if he has any).
Powers and Abilities
Wavelength is known to possess weather abilities. His design suggests his internal hurricane could wreak havoc a la suit-less NRG. At the very least, contained, he is able to manipulate localized winds so strong they can levitate people, but not cause any other major damage.
Back in Action: Alien Universe
Ben debuted Wavelength in Foreverlasting where he sought information from an ultimately innocent man he mistook for a Forever Knight (per Forever King Eli's plans).
