The blade was created and infused with an essence by Oz Pone Max Reinhardt as an attempt to counter Void's Eclipse. However, the ego refused to let his creator or anyone else wield him, as they were deemed "weak". After a long time, Oz artificially created a stronger body, Zero, whom Grandark accepted as his wielder. According to an interview, it is said that Grandark's ego is "strong enough to bring Ancients down to their knees". In the dialogue of Kamiki's Castle, Zero dragged Grandark along the ground as he wandered the world, leaving odd markings in its place.
