Sexecutioner is a supporting character in the heavy metal band Gwar, played originally by Mike Delaney, and finally by Chuck Varga from 1989 until 1995–6, with special appearances in 2000 (the You're All Worthless and Weak concert), 2012, and 2014. He sang lead on his trademark song, "Sexecutioner", and "Ragnarok".
There are conflicting origin stories of the Sexecutioner - the Slave Pit Funnies (from 1989–90) suggest that he was summoned in an ancient ritual by Oderus, and was raised from infancy to become Scumdog material.
