DC Super Hero Girls Wikia
Ally CatGalleryTranscript

The Book of Eternity. The great wizard Merlin wrote it over 1,500 years ago. It gives whoever holds it the power to know, and thereby control, the future. The Ancients buried it under Stonehenge to keep it out of the hands of mortals. Nobody should have that book!
~ Zee Zatara

#AllyCat is a special comprised of the thirty-third and thirty-fourth episodes of Season 1 of DC Super Hero Girls.


Lex Luthor discovers the Book of Prophecies, where he can create any future he wants. Zee worries that Lex will use it for evil, so the girls are about to break in LexCorp to retrieve the book, until Babs was forced to go with her dad. Now, the rest of the girls reluctantly need help from Catwoman to sneak in LexCorp, though it was not as easy as she predicted. As they go inside his secret base, Lex reveals himself as a criminal mastermind and shows the girls the captured Invinci-Bros, including Superman, who is incarcerated with Kryptonite. As if it was not bad enough, Catwoman unironically betrays the girls and joins Lex. With the Book of Infinity in his hand, Lex effortlessly defeats the girls and locked them up inside. As they were about to head out, Lex tells Catwoman that what he wrote in the book is to predict a meteor that will destroy Metropolis so he can enslave the survivors and rule not just what's left of Metropolis, but the entire planet. Catwoman is shocked about Lex's evil plan, so she sneaks back into LexCorp and frees the girls to stop Lex. Supergirl destroys the meteor that Lex predicted, while at the same time, Catwoman ripped out a page from the book and steals it from Lex, though the girls retrieve both from Catwoman. While Babs was disappointed that they saved the world without her, the rest of the girls are disappointed that Lex wasn't revealed as a criminal mastermind and that he remains a good guy to the world. Meanwhile, Catwoman sneakily steals all of Lex's gadgets and food from him, with the Bros and Superman still locked inside.




  • This is the first episode to air in 2020. It also aired on the first anniversary of the TV series.
    • Much like "Sweet Justice," this episode premiered on International Women's Day.
  • This is the first episode to have a different animation studio. In this case, this was animated at Boulder Media[1].
  • This episode was first revealed in a tweet[2].
  • Though this is the thirty-third and thirty-fourth episode aired, a Cartoon Network press release lists it as the thirty-ninth and fortieth.
  • Lex Luthor makes a reappearance from "Sweet Justice".
    • Also, this is the second time Bumblebee got shocked.
  • Promotional material erroneously refers to this episode as "Alley Cat."
  • The color of Zee's hair changing from purple to black is a reference to how she has black hair in the DC comics.
  • Green Lantern (Hal), Hawkman, Aqualad, and Green Arrow don't have speaking lines.


  • After the girls and Catwoman fell into Lex's private elevator, Jessica is shown to have four toes rather than five. Also her leg is shown to be bare despite her waitress outfit having her wear black pants.


  • The promo poster is a reference to the 2018 film, Ocean's 8.
  • Lex Luthor's secret lair is located on the 38th floor. This is a reference to Superman's first appearance: Action Comics #1, published in April 1938.


  • This is the fourth half-hour special of the series. The previous ones were "DC Super Hero Boys", "Frenemies" & "Soul Sisters".
  • This the fifth time one of the main characters does not transform into a hero, in this case, Barbara.
    • The main reason why is because she had to visit her grandmother for the weekend.
