Darth Krall, originally known as Radaki, was a male Force-sensitive individual. A former member of the Jedi Order, Radaki became part of what was later known as the Lost Twenty and was seduced by the dark side of the Force as a result of his belief that the Jedi should retain their family ties and wealth. Having forsaken his allegiance to the Order, he adopted the name of Darth Krall and became a powerful Sith Lord.
As a Sith, Krall wore a black and red cloak and wielded a Sith lightsaber with a golden hilt. Krall participated in the Battle of Wasted Years, emerged victorious, and tamed the Nightmare Conjunction. His lightsaber was stored in the Bogan Collection at the Jedi Temple on Coruscant. He had purple skin and sharp teeth.
Darth Krall was mentioned in the 2019 canon audiobook Dooku: Jedi Lost, written by Cavan Scott. The spelling of his name was given in the script of the audiobook.
