I remember many of these. I really made
Transformers a case in point (I was obsessed with it when I was young

), but I also had watched the following:
Thundercats, Silverhawks, GI Joe, Astro Boy, Denver the Last Dinosaur, Dinosaucers, Captain Planet, MASK, Ewoks, and, of course,
Teenage Mutant Ninja Turtles. Most of these, I was obsessed with well before I came to
Doctor Who at the age of 8.
Of course, I didn't stop watching them when I came to
Doctor Who. I also remember
The Twins of Destiny, as well as the anime series
Pokemon and
Dragonball Z. I still enjoy the latter.
