Madame Olga

Madame Olga was a fortune teller and grifter who traveled as part of Master Payne's Circus of Adventure. She was killed when a crab monster clank attacked the circus, and her burnt body was dressed in Agatha's things, tricking Bangladesh DuPree and thus Baron Klaus Wulfenbach into thinking Agatha had died.

Klaus rebuilt her body, but her brain was a lost cause.
