The Beat-Alls were a team of supervillains comprised of Mojo Jojo, HIM, Fuzzy Lumpkins and Princess Morbucks. As the name implies, they are a parody of the 1960's group, The Beatles.

When the villains Mojo Jojo, HIM, Fuzzy Lumpkins and Princess Morbucks defeated the Powerpuff Girls one night, they discovered that together they could be unstoppable. So together, they formed the Beat-Alls. The Powerpuff Girls were no match for their teamwork attacks, so the girls used a chimp named Michelle (under the name of Moko Jono, a parody of John Lennon's widow Yoko Ono) to get Mojo to fall in love so that the team would have to disband.

Eventually, the team disbanded because they couldn't stand Mojo and Moko.

They were only a team in "Meet the Beat-Alls", but they do reunite in the video game HIM and Seek.
