Adapted from an Archie spin-off comic, the animated version differs from the actual comic most significantly in the characters of Alexandra, Sebastian, and Alexander. In the cartoon, Alexandra and Sebastian are simply conniving and sneaky; in the comic book, Sebastian is the reincarnation of a witchcraft-practicing ancestor of the Cabots, and Alexandra can cast powerful magic spells while she is holding him. In the original Archie comic, Alex is a snide braggart who lords his wealth over everyone and sees Alan M. as his rival for Josie's attention. In the animated series, Alex is a meek coward who brags much more about the band's talent than his wealth, and expresses no romantic interest in Josie.
