Biography
From the Malice from the future of the Great Calamity, Calamity Ganon had sent parts of itself through the HWAoC: created by Terrako to prevent any changes to its awakening. By possessing the inactive Terrako of 100 years in the past, it became the Harbinger of Ganon and was soon allied with Astor. Using what power it has, it uses its Malice to possess a Guardian Stalker to attack Zelda on her way to the Ancient Tech Lab and reveal Calamity Ganon's awakening in the future to Astor and the Yiga Clan.

It leads an army of monsters to attack Rito Village which is defended by the soon-to-become Champion Revali and his Rito brethren, thus creating paranoia among the Rito to attack Link when they were to see Terrako with him.

Harbinger Ganon reveals itself to Zelda and her allies floating beside Astor before they enter the Malice-filled Hyrule Castle, opening up its body to draw out its Guardian weapons and claws to show intimidation. Zelda in particular noticed its similarities to Terrako and realizes that Harbinger Ganon must have been responsible for causing the Rito to become paranoid and hostile to her group. It awaits inside a gatehouse of the castle, hanging upside-down in a pile of Malice on the ceiling, engaging Zelda and her forces as soon as they arrive.

After being defeated along with Astor, just before Astor could call out a command to destroy the heroes, Harbinger Ganon consumes the prophet for his power, using it to transform itself into its true form - Calamity Ganon.
