Following is the series finale of Super Friends: The Legendary Super Powers Show:
"Village of Lost Souls": Brainiac (Stanley Ralph Ross) enslaves the Wonder Twins, sending them to capture Wonder Woman. Apache Chief may have something to say about that.
After that, Superman, Firestorm, & Samurai deal with "The Curator".
It's also part 2 of our Valentine Toon Crush series, and in "Village", you can take your pick between Wonder Woman & Jayna.
Need I add the Wonder Twins miniseries from DC's Wonder Comics imprint arrives in stores this week?
This was also the only time the Twins used a telepathic link between them, something not previously established, and, contrary to what Wikipedia might suggest, it may have been a 1-time plot contrivance.
