Adaptation Displacement: The comic has been displaced by the cartoon, film, and even the Groovie. It doesn't help that the characters only appeared in comic cameos for decades, from the 1980s until the 2010s reboot gave them their own series again.
Audience-Alienating Premise: This is the reason why the manga adaptation didn't last very long. It was not popular among readers due to the Pussycats' backstory being completely retconned, and some of them preferred the traditional art style and didn't find the new one very appealing. Not to mention that some of the new characters introduced in the series (such as Alan M.'s little sister Alison and the Pussycats' rival group The Vixens) didn't appear in any of the original comics. Needless to say, complaints from the fans caused the manga adaptation to be canceled and the story ended on a cliffhanger.
The Cartoon
Awesome Music: While the original main theme is quite fun on its own, in 2001 an animated short, "Musical Evolution", was aired showcasing the main theme in a variety of musical genres and matching animation styles.
Damsel Scrappy: Never mind that Alexandra's schemes fail disastrously each time. She is the first to shout for help when disaster strikes her!
Foe Yay Shipping: Alexandra and Melody are probably the most popular pairing.
Growing the Beard: In Outer Space actually improved the show as it got the gang away from Scooby-Doo–type adventures and just put them in weird settings that didn't require someone to be in disguise (but Alexandra's main concerns were still replacing Josie).
Jerkass Woobie: Alexandra has no actual purpose in the show except for being a bitch and causing everyone's problems, but you can't help feeling bad for her. Surely she may deserve her pain, but all she wants is to be noticed.
Valerie being a tambourine player in a rock band gets poked fun of a lot. The comics switched her tambourine for a guitar, but the image of her playing a tambourine has stuck around nevertheless.
