Mayor is a minor character who appears in Stealing the Diamond.
He is a mayor of a town in which the museum is located. He announces that the grand exhibit, where you can see the famous Tunisian Diamond, is open. He appears on TV announcing it's opening. His clip on the news inspires Henry to steal the diamond.
- Although he is a stick figure like others, he is the only character in the series who has actual torso design with clothes. This is probably to make him look fat.
