The Legion of Doom have captured Wonder Woman and Aquaman and are lowering them into a vat of acid in the lair, the Hall of Doom. Just then, the Powerpuff Girls smash through the ceiling to save them. Lex Luthor is surprised and shouts: "The 'Powderpuff' Girls?!" The girls correct him and tell him there's no "D." But he responds by telling them there is a "D" in destroy...as in "Destroy them." The other supervillains are silent...as if they didn't get the joke. But he repeats it, and they then realize that this was their cue to attack the young superheroes. The Powerpuff Girls beat the living snot out of the villains who fall to the ground.
