Who's the worst fighter to fight in Zuffa's UFC?

Khalib Starnes?

Well maybe the worst fight in UFC, not the worst fighter.

Probably Mark Robinson. Guy was a power lifter with a very limited Judo and Sumo background. Phone Post 3.0

I could be wrong, but I believe in the entire history of Zuffa-owned UFC only one fighter had exactly zero professional fights before making his octagon debut.  Whether that makes him the worst fighter ever is questionable, but it certainly makes him the least deserving to ever get a UFC fight.

It's obviously the dude that used to be CM Punk.
