Artificial lungs and voice box grant: Formerly: Malcolm Arnold "Mal" Duncan, currently known as Vox (also known as the Guardian, Hornblower, and Herald), is a superhero appearing in media published by DC Comics.

[4] Malcolm "Mal" Duncan[note 1] saves the Teen Titans from a street gang called the Hell Hawks by beating their leader in a boxing match.

[5] Recruited by the Teen Titans, Mal feels unworthy due to his lack of abilities, and stows away on a rocket flight, which nearly costs him his life.

[12] He and Bumblebee then join a team of heroes gathered by Troia to embark on an ominous mission into deep space during Infinite Crisis.

The team of heroes in space temporarily stop Luthor, but in the resulting chaos they are scattered; some are killed, while others go missing for varying lengths of time, including Mal and Karen.

[14][15][16] In The New 52, a reboot DC's continuity, Mal is introduced as an award-winning film composer and the husband of Karen, who is pregnant with their daughter.

The Titans had allowed their memories of each other to be erased to defeat Twister, but he now seeks to use Mal's sonic abilities to summon a demon.

[19] Following this incident during DC Rebirth, Mal reveals to Karen that he underwent a procedure to remove his superpowers so that the couple could live a normal life.
