Biography
From the Malice from the future of the great Calamity, Calamity Ganon had sent parts of himself through the Time Warp portal 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 had, it using 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 had lead an army of monsters to attack Rito Village which was defended by the soon-to-become Champion Revali and his Rito brethren, thus creating a paranoia among the Ritos to attack Link when they were to see Terrako with him.

Harbinger Ganon revealed itself to Zelda and her allies floating beside Astor before they entered the Malice-filled Hyrule Castle, opening up its body to draw out its Guardian weapons and claws to show intimation. It waited 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 arrived.

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