"Michelle Leupi" was a Chameleon who took the form of Polly Wright.
Michelle claimed to be from Zurich, explaining her fluency in the English language as being thanks to an English governess. She worked for Chameleon Tours but was due to be returned to base because of the attentions of the Second Doctor and Jamie McCrimmon. She alerted Captain Blade to Samantha Briggs's inquiries.
