Yapyap

Not to be confused with Yayap.

Yapyap, self-proclaimed Yapyap the DESTROYER, is an Unggoy leader who rebelled against the Banished during their battle with the crew of the on Installation 00.

Biography
Yapyap was a low ranking Deacon in the Covenant's Ministry of Sanitation before being kidnapped by the Banished.

Yapyap rose through the chain of command within the Banished due to being slower than the other Grunts at avoiding eye contact when a job needed to be filled.

After discovering the Throne of Woe and reclaiming the High Prophet of Truth's crown for himself, Yapyap rebelled against the Banished in favor of locating the fabled Golden Methane Hydrate Mines of Sabator, hidden somewhere on the Ark. Throughout his rebellion, the Throne of Woe continued to communicate with him, telling Yapyap that the Ark belonged to the Unggoy. Yapyap managed to lose more Unggoy in battle than were even carried to the Ark in the first place. The Throne of Woe would somehow produce Unggoy reinforcements for Yapyap after he argued with and kicked the Throne.

Because of Yapyap's forces dealing with the Ark's defensive systems, Atriox tolerated Yapyap's activities on the Forerunner installation, but with Let 'Volir now leading the Banished forces on the Ark, it is unlikely that Yapyap's rebellion would continue any longer.

Equipment
Yapyap uses the point tank model of the Unggoy combat harness, engraved with multiple carvings. He also has a Hierarch crown with a small statue of Installation 00 crudely tied onto it. It was later revealed to the crown of the High Prophet of Truth.
