Brogo is one of the three sons of Gorgrog. It has been noted that he attacks castles unaided, fell forests single-handed, destroyed cities, and ruined monuments. He was the first one to be locked up in Zzyzx. He did not show to be very smart. He was so strong he survived having part of an arm torn off.
Brogo is one of three sons of Gorgrog, the Demon King. During the opening of Zzyzx, Brogo was shirtless with gray elephant-like skin and big muscles. In one hand was a mace, in the other was a tremendous morning star. It never says who killed Brogo or if he even got killed, but all facts face that he got trapped in the Fairy Queen's shrine on Shoreless Isle with all the other demons from Zzyzx.
