Technobeast Jedi
From Wookieepedia, the Star Wars wiki.
The Technobeast Jedi was a Jedi during the New Sith Wars. During the Sictis Wars, he became infected with the nanovirus that Belia Darzu used to create the Technobeasts. Through the Force, he was somehow able to prevent the lobotomizing of his frontal lobes and retain his identity. The Technobeast Jedi would go on to fight the New Sith Empire and serve the galaxy for many decades.
