Archie Comics

The Archie Comics universe primarily stars a cast of normal teenagers, all of whom have had bathing or showering scenes:
 * Archie Andrews
 * Betty Cooper
 * Jughead Jones
 * Reggie Mantle
 * Veronica Lodge
 * Hiram Lodge, her father

They are linked to anime because they have had crossovers with both the Marvel Comics and Teenage Mutant Ninja Turtles universes, both of which have had direct anime adaptations of many central characters.
