Bruni

Bruni is a character in the 2019 sequel, Frozen II. Curious and cute, this salamander inhabits the Enchanted Forest. Though shy at first, Bruni can't help but be drawn to Elsa's icy magic and enjoys the cool snowflake treats she creates.

When set loose, he sets the entire forest ablaze, creating fires all throughout his path. He burns Elsa's hand, but she manages to calm him down, and when he calms down, so do the forest fires. He can hear the same mysterious voice that Elsa hears and always looks to the north, guiding Elsa's way.

To the Northuldra, he is known as simply the Fire Spirit, with the nickname "Bruni" given to him by Anna, Elsa and the others of their group according to supplementary material, though the name is never used in the film itself.

Bruni is one of four elemental spirits in the forest, the others being the water spirit The Nokk, the Earth Giants and the wind spirit Gale.
