Marcus Wendell is the owner of a casino, whose ancestor kicked Albert's great-grandfather Charlie Stroller off his first casino steamboat. Wendell's most significant feature is his habit of taking photographs of people he finds cheating at his casinoes and subsequently sending those photos to all other major financial institutions, thus putting grifters out of business as they are now incapable of scamming anyone. Although Wendell claims that he only ever goes after grifters, he has been shown to throw people out of his casino on relatively flimsy excuses; on one occasion he apparently threw a teacher out simply because she knocked over a pile of casino chips.
