The Great Main Brain.
The brain that rules over all brains.
The Great Main Brain before him differed from other Su'en Elder Brains. Before entering the Distant Realm, it was already a Challenge Level 25 fleet Main Brain. Other Su'en Elder Brains were partly transformed from immature Main Brains back then and partly created through a blood sacrifice ceremony twisted by the Old Ones, which required sacrificing many Heart Stealers and storing their excavated brains together alive.

The Great Main Brain differed from other Elder Brains; it was Su'en's chosen one.
