Zebub was a Tsutsaroth demon commander who fought for Zamorak during the early God Wars. Zebub is mentioned only in the FunOrb strategy game Armies of Gielinor, the lore Twice Burnt, and Zemouregal's memory.
In Armies of Gielinor, players must fight Zebub and a number of other Zamorakians on Entrana as part of the Saradomin Strikes campaign's first level, Deus Ex. Having died in the Third Age, Zebub makes no appearance in the RuneScape game itself. In the lore Twice Burnt, it is revealed that Zebub led a force that destroyed the city of Onkhara.
- Zebub's name may be a reference to Beelzebub.
