When Heroes Unite: After Dark is a series of special episodes that happen in between some episodes of When Heroes Unite and When Heroes Unite: The Next Generation. While generally to tell what happens on the night of episodes that end at nighttime, some episodes contain minimal (Not completely) erotic moments, such as a guest, recurring or main character (Mainly female) walking around naked, being super drunk (If adult]], and generally doing stuff much to the male characters' chagrin (Most of the time).
