What is the name of the leader of the trolls in Frozen?

Grand Pabbie is the leader of the trolls in Frozen.

He belongs to the troll colony living in the Valley of the Living Rock. Grand Pabbie is distinguished by his unusual magical abilities and his role as the colony’s wise elder. When Anna is accidentally struck by Elsa’s ice magic as a child, her parents bring her to the trolls for help. Grand Pabbie removes Anna’s memories of Elsa’s powers, leaving her memories of ordinary sisterly play intact.

Years later, Anna is struck in the heart by Elsa’s magic. Grand Pabbie explains that only an act of true love can save her, setting up the film’s central reversal: the necessary act comes from Anna’s self-sacrifice for Elsa, not from Hans’s romantic kiss.

Bulda is another named troll, but she is Kristoff’s adoptive mother rather than the colony’s leader. “Elder Troll” and “King Troll” are descriptive-sounding distractors, not the character’s canonical name. Grand Pabbie also appears in Frozen II, where he and the troll colony arrive in Arendelle after the spirits disturb the kingdom and advise Anna and Elsa to seek answers in the Enchanted Forest.
