Kae Kwaad
From Wookieepedia, the Star Wars wiki.
Kae Kwaad was the alias used by Onimi when he went to observe Nen Yim on Baanu Miir. In appearances, Kae Kwaad had two shaper hands, both of which died, but the other Master Shapers had not given him a new one. Nen Yim soon realized why: he was insane. He also referred to Nen Yim as Nen Tsup, meaning she was an unseemly slave. When he demanded Nen Yim create the perfect grutchin, she decided to murder him. Kae Kwaad then asked Nen Yim to make him a new pair of shaper hands, by allowing her to access the eighth cortex, but while she was examining it, he destroyed the grutchins they were making. Kae Kwaad then took her to Supreme Overlord Shimrra, who then commanded Onimi to reveal himself.
