As it's Good Friday but we all seem to be moaning our heads off once again (and rightly so - Matty and DR, you should be disgusted at yourselves, especially for international fans still awaiting items from the end of last year onwards!!), here's a more creative thread topic.

What "unexpected twist" could be introduced into the Classics continuity to really shake things up?

I'm kinda talking the equivalent of the revelation of Adora / She-Ra's existence in 1984/5. Six months previously, who would've ever magined that Adam had a sister abducted as a child, who is actually a super-woman equivalent of He-Man?

So kinda like that. Yes we've had various canon worked into this "one continuity" vision (the Cosmic Key, Marlena from Earth, wonderful inclusion of unproduced prototypes as "new" characters, so many others) on a secondary scale, but what seriously big "twist" could be introduced to the Classics canon to really add some new spice?
(Note I'm thinking on the lines of something new and totally unexpected, not the kind of "introducing (previously unseen but mentioned race" into the line, etc.).
