I`ll give a few hints.
1) Even though there are 3 blanks in the question, once you find one answer they should all be there or very easy to find now that you know what to Google for.
2) There's a couple steps to finding the answer as I didn't want it to be easy as just Google`ing the names involved..or even the TF series in question. Would be too easy that way.
3) I did give decepticon a hint when he PMed asking for clarification on something so I`ll share it with you all. After the Generation 1 TF series ended in the US, it continued in Japan for over 100 episodes. This comes from some of those episodes.
