in one star wars book theres some mutated jedi withlightsaber comin out of knees and elbows who is he?

Question

and wat book did he come in

Answer 1

I actually spent some time working on your question last night. I'm surprised there are no Star Wars fans who have answered you.

If you want to to a little legword, I will tell you that someone has gone to a great deal of trouble to list most of the characters in Wikipedia.

Good luck.
