- [opening narration]
- Narrator: Deep within a bleak and dismal swamp, hidden beneath its murky waters, lies the headquarters of the most sinister villains of all time: The Legion of Doom.
- [first lines]
- Lex Luthor: The meeting will come to order. The Legion of Doom is now in session. It is the purpose of the Legion to align our infamous forces against the powers of good and defeat them, leaving us the rulers of the world. To do this we have gathered together the thirteen most ruthless villains on earth: the frigid Captain Cold; the sinister mind of Sinestro; the awesome Bizarro and Solomon Grundy; the cunning Cheetah and the super-intelligent computer android Brainiac; Black Manta and Grodd the Gorilla; the Toyman and the humorous but sinister Riddler; the feminine yet ferocious Giganta and the hideous Scarecrow; not to mention the evil genius and brilliant leadership of myself: Lex Luthor.
- The Flash: It started with an incredible dream I had last night.
- Superman: No more strange, I'm sure, than the one I had. I dreamt I robbed Fort Knox.
- Batman: That's interesting. I dreamt Robin and I looted the U.S. Mint
- Robin: Holy coincidences, Batman! I had the same dream.
- Hawkman: It seems we all had criminal dreams last night. But when we arrived at the Hall of Justice this morning, we discovered something that turned our dreams into nightmares.
- Black Manta: It's time for us all to go to the Hall of Justice and turn it into the Hall of Injustice!
- Narrator: Can the SuperFriends escape before they collide with the sun? Will the Legion of Doom succeed in taking over the world? Stay tuned and see in the exciting conclusion of: The Challenge of the SuperFriends!
- The Cheetah: With Luthor's brilliant mutation device hooked up to the SuperFriends' computer, the Justice League satellite will beam its rays all over the world.
- Bizarro: Turn all Earth people into Bizarros and Cheetahs.
- The Cheetah: And all of them working for our evil purr-poses.
- Batman: Alfred!
- [Alfred enters with a mutated face]
- Alfred Bizarro: Alfred Bizarro to be exactly. Now me got little surprise for you.
- [Batman and Robin are tied up in the Batmobile, which is about to go over a cliff]
- Robin: Holy Houdini, Batman! We'll never get out in time.
- [Bizarro has wrapped a steel girder around Batman and Robin]
- Robin: Holy metallurgy, Batman! We're trapped.
- [Batman releases an object from his utility belt that expands and traps Bizarro]
- Batman: What's the matter, Bizarro? Can't even punch your way out of a plastic bag?
- [last lines]
- Lex Luthor: We're already back at the Hall of Doom planning our next sinister mission. And this time, nothing will stop us.
- Superman: Give it up, Luthor! You've failed this time, and you'll fail every time you try to triumph over justice - and the SuperFriends!
