Zhan Tiri

Zhan Tiri is an antagonist from Tangled: The Series. He is an ancient evil warlock and was the archnemesis of Lord Demanitus, he was first mentioned in the episode "Queen for a Day".

Description
In Corona myth, Zhan Tiri was a powerful demonic being from another realm who unleashed an all-consuming blizzard on the kingdom that threatened to destroy everything in its path. The only one who was able to stop the warlock was a man named Lord Demanitus. Using magic and science, Demanitus built a device strong enough to change the storm back into the direction of Zhan Tiri to imprison Zhan Tiri and his disciples (Ms. Sugarby, Matthews and Mother Gothel), saving Corona from the warlock's wrath. But Zhan Tiri's defeat did not leave him abated; his magic storm remained in Corona as a curse that waited for Corona to be at its weakest and strike again.

Season One
Zhan Tiri was the subject of the episode "Queen for a Day", where the storm curse he had cast long ago had returned to reclaim Corona, though the disaster was ultimately averted by Rapunzel. His storm's story was told to the people of Corona by Xavier, as he hinted and show Rapunzel and Cassandra the device that stopped it.

Zhan Tiri's presence became known in the episode "Painter's Block", in which one of Zhan Tiri's spirit allies, Sugracha the Eternel, under the guise of a painter named Ms. Sugarby, managed to escape their prison, and formed a plan to free him as well. Zhan Tiri was close to being freed, until Rapunzel, whom Sugracha had under her spell, broke free from it and made sure that her master would remain in his prison.

Season Two
Zhan Tiri is mentioned in "Rapunzel and the Great Tree". As told by Adira, Zhan Tiri took over and corrupted the Great Tree, taking it as his fortress to destroy all who approached. Ultimately, Lord Demanitus put a stop to Zhan Tiri's reign with a magic spear that rendered the evil magic in the Great Tree dormant.

In "You're Kidding Me!", one of Zhan Tiri's disciples, Matthews, later revealed in "Rapunzeltopia" to be Tromus, vows to keep the Sun Drop (Rapunzel) trapped within the House of Yesterday's Tomorrow forever. Subsequently, Tromus traps Rapunzel in a dream world where she never touched the black rocks, with the intent of ensuring that she accepts the illusion, all the while transferring the Sun Drop's power to Zhan Tiri, personified by an eerie statue. However, Rapunzel is able to break free of the dream world, causing Tromus and the House of Yesterday's Tomorrow to vanish into oblivion, once again thwarting Zhan Tiri.

Role in the series
Zhan Tiri is revealed in Princess Salvation in lore to have been a minor Darkspawn lord who aimed to destroy the Lightflies and Mothrons and steal their power starting with Corona's Sunstone and Moonstone, the celestial relics responsible for the Sundrops and Moondrops that each have sentience of their own, and the power they bestow, seeing control of both light magic and dark magic in equal and opposite power as the best prize of power. But Lord Demanitus stopped this many times, as he swore an oath to keep the power of the Sunstone and Moonstone safe from those who would abuse them. Though not the prominent evil of the episode, much of his secrets have been stolen by Profligo the Hurt, the creator of the Moonstone.
