He never stated that, but yes: Mal Duncan had adopted the codename herald in the DC universe, as well as Guardian, Hornblower and Vox. He got his powers from the Horn of Gabriel, initially this was given to him by Angel Zauriel after he defeated him as Guardian. Later he remade the horn himelf using technology and used this until it blew up in his face in a zeta beam accident (DC has a lot of them) and the tech were attached to his body as cybernetics to replace his damaged voice box.

Since Jim Harper has retired as Guardian, most are hoping for Mal to assume the Guardian alias, less complex then hornblower, herald or vox, and I for one would rather see a Guardian in action on a regular basis then a big dude with a trumpet.
