Lofty (The Girl Who Died)

Brot, nicknamed "Lofty" by the Twelfth Doctor, was a Viking blacksmith who was trained to be a warrior to fight the Mire.

After the Mire abducted the village's warriors and Ashildr had declared war on them, Brot was one of the ones who was chosen to train with the Doctor to become a true Viking warrior. He was perplexed when the Doctor rejected his true name and instead began to call him Lofty.

He was trained by the Doctor to fight with a sword, but he eventually came to terms with the Doctor's plan of using electric eels to generate electricity to defeat the Mire.

Later, when Odin arrived with the Mire in tow, Brot was partying with the others when Einarr activated the electric eels and Ashildr, through a Mire helmet, projected the image of a dragon attacking the Mire. This scared them off, and the village celebrated over their retreat. (TV: The Girl Who Died)
