Marc O'Neill isn't sure whether it was from a nasty flu or from screaming with the crowds at a Foxbatcon-- but when his mutant powers manifested, his perceived inability to speak isolated him from his family and all else around him. It wasn't until his father turned on a radio a few weeks later when the nature of his abilities became clear: Marc's voice had changed to a form of electromagnetic signal.
Marc secretly attempted to moonlight as a vigilante crimefighter of sorts, despite the limited usefulness of his powers. While in pursuit of a Cobra Lord footman with a stolen purse, he encountered the hero Sabotage, who directed Marc to meet with someone who could help him harness his powers. After obtaining a suit and electronic apparatus with which he could project his voice for others to hear somewhat normally, he made up the identity of Communick and resumed his endeavor to become a hero in his own right-- encountering the Progeny by accident when his voice transmitted over their private communication network.
One of Marc's misadventures with the team has irrevocably changed the course of his life. While investigating the cause of several metahuman deaths, Marc chased after a drug dealer who was peddling a mutagenic serum-- only to be overwhelmed by the man and have some of his drug directly injected into his bloodstream. The experience was ultimately responsible for uncovering new abilities for Marc to develop, but such power came with a cost...
Marc carries himself with a rather short and stocky build, and has the average strength and slightly above average stamina of a young man his age that engages in regular, moderate exercise.
Powers and Abilities
"Radio Voice": In lieu of direct speech, any sounds Marc produces naturally occur as a projected form of electromagnetic radiation akin to radio waves. This allows him the potential to communicate over long distances through media that can pick up his vocal frequency. He is able to "tune" the frequency at which he speaks (mostly) at will. Due to the nature of his speech, his voice may be subject to occasional interference (#) when needing to transmit over long distances.
Radio Hearing: Marc has the ability to hear forms of electromagnetic radiation, including his own speech, without the assistance of equipment. Like his speech, he is able to tune in and out what exactly he can hear.
Radar Vision: With exposure to the mutagenic serum rendering him effectively blind, Marc developed the ability to "see" via the electromagnetic spectrum.
Personal Vibratory Field: Marc has the ability to generate a "sonic force field" of sorts that covers the entirety of his body. The strength of this field can increase involuntarily when Marc is stressed, or has an excess of adrenaline-- at high intensities, the field is capable of harming others that come into contact with it.
Equipment and Other Paraphernalia
Personal Broadcasting Apparatus: Consisting of a helmet with a built-in transceiver and interlocking chinguard, and speaker systems mounted on the collar and shoulder pads.
Radar-Sensing Goggles: Previously allowed Marc to sense radio waves visually. With his ability to achieve this effect naturally, the goggles now enhance his radar vision to pick up slightly more details.
Boost Boots: Since he is not gifted with a natural means of advanced travel, the Boost Boots allow him to jump great heights and distances when activated at the push of a button.
Faith: First met prior to her introduction to the team, during the "Alligators in the Sewer" incident, in which the young heroine attended to the addled hostages rescued by Marc, Oliver, and the alien Kl'vin.
Kid Ballistic: Having figured out the nature of his powers upon meeting him, Sid cautiously let Marc borrow his Progeny communicator on the promise that he would come to retrieve it sooner rather than later.
Blitzkrieg: Even with the experiences of meeting the members of his would-be superteam, Marc's encounter with army captain Jacob Raines ranks as one of his biggest influences in choosing to embrace his gifts. Marc treasures the military hero's autograph, which reads "Don't be afraid of being different".
Constructor: Introduced by the bionic-limbed hero Sabotage, this mysterious benefactor provided Marc with his initial equipment-- crafted with the use of his metal-manipulating powers and made of metal derived from signature Polarium alloy. The Constructor, despite his generosity, was less than pleased to hear that Marc was using his gifts for heroism. The episode caused a rift between the two, and Marc has since been advised to avoid contact with him in the future.
Dr. Samuel Solomon: A prodigious researcher and technician that took on Marc's case after his powers were altered by the mutagenic serum.
Staredown: The heroic identity of paranormal fiction author Isaac Blaylock: though Marc has met both, he does not know they are one and the same. Staredown's powers involve the manipulation of energy, usually focused as blasts from his eyes.
Is still very much "learning on the job".
Untrained, his radio voice is unwieldy and might get picked up by established frequencies as interference.
