Pepper is the perfect caricature of the American teenager, bombarded by an endless stream of popular culture and driven to maniacal adoration for any and all celebrities. On Histeria!, Pepper Mills is allowed access through the barriers of time and space, harassing history's most significant stars as she flips and screams her way into their lives. However, she has a bit of a problem getting her facts straight, often confusing history and Hollywood. Upon meeting Joan of Arc (just as she was being burned at the stake), she left feeling gyped that she hadn't just met Sabrina the Teenage Witch. Always up for an autograph, Pepper has mistook such historical figures as Rosa Parks for Whitney Houston, Teddy Roosevelt for Winnie the Pooh, Sergei Eisenstein for Steven Spielberg, Vladymir Lenin for John Lennon, and an aging, emaciated Nikola Tesla for Calista Flockhart. But despite her bad luck at meeting any movie stars or pop musicians, she has managed to collect enough of history's most famous signatures in her autograph book to make her the envy of any historian.
