OK, I'm far too late judging by the number of responses, but I'll attempt to answer them anyway.
1. How many different Voltrons were there? What were the differences? For bonus points, recall the saying that went along with one of the Voltrons being put together.
There were two that I can think of - the boring-as-hell vehicle one where there were like 50 different bits that joined together, and the far superior and absolutely awesome Lion Force Voltron.
I think it was "Arms, legs, torso... and I'll form the head!"
2. Name all 4 Ninja Turtles, the Scientist that turned into a fly, the guy with the hockey mask, the villains mode of transport and the pink blobby villain from the Ninja Turtle cartoon series.
Donatello, Leonardo, Michelangelo and Raphael. Dunno the fly... the guy in the hockey mask was Casey Jones. Can't remember the villains' mode of transport (they were foot soldiers though!) and can't remember the pink guy... sigh. Loved that show, never read the comics though.
3. Name all the members of G-Force and the villain of the series. What colour was the spaceship they used?
Pass.
4. What is Lion-Os famous catchcry? Name the villain of the thundercats.
Ooh, Thundercats. One of those shows I should have watched all the time but didn't because I thought it was an average ripoff of Masters of the Universe. Therefore I can't remember much of it at all except for the rockin' theme song, which went something like "Thundercats are on the loose, thundercats are loose! Feel the magic, feel the roar, Thundercats are loose! Thunder thunder thunder thundercats!". Or something like that, anyway.
5. Name the 5 dinobots.
From Transformers? Doh, can't remember them off the top of me head!
6. Will the Coyote ever catch Roadrunner?
He did once, if I remember correctly.
7. What was the name of He-Man when he wasnt transformed into He-Man?
Prince Adam. Easiest question ever. And most obvious disguise ever.
8. What was the name of the crashed ship that was shot down defending the Earth in Robotech?
Dunno, never watched Robotech much - too grown-up for me at the time.
9. Name 5 Care Bears. What was the name of their Kingdom and mode of transport?
Can't remember... but the very first (and so far only) non-monetary prize I won for entering a competition in the kids' section of the Sunday paper was a Care Bears jigsaw puzzle.
10. Name 2 Snorks.
Dunno.
Hmm, maybe I should hand my "Child of the 80s" membership card in. Sigh.
And the Thundercats and the Dinobots head back to the pavillion!
