Mr. Sullivan

Mr. Sullivan, the head of the Bank of England, is a wolf and rival of Willy Fog in the Reform Club. He accepts Fog's bet and, determined to ensure Fog's failure and expose him as a "worthless bragger", decides to send a saboteur, Transfer, after Fog's steps. Following Transfer's failure to stop Fog he is sacked as head of the Bank of England on charges of misappropriation of funds.
