My my, I almost forgot the great Dexter's Laboratory (seasons 1-2). I watched it when I was no longer such a little kid, on Cartoon Network via analog satellite (RIP). Together with BBC World it helped me enormously with my English.
And Knights of the Zodiac (Saint Seiya)! They were really big in Spain. Looking back at it, it still looks pretty good with its characters and mythology in the first Sanctuary story line. Later it fell into easy trite formulas based on nothing but absurdly long and absolutely pointless fights, much like Dragon Ball Z.
Of course there's nostalgia but there are some kid shows that I can rewatch still now because they're so good. Not really TMNT beyond a couple of episodes, but definitely Dragon Ball for example (even if some Philistines deny it). Not DB Z, I couldn't watch again through one single episode from Freezer onward, even though I followed it back then. Dragon Ball is awesome (not DB Z or later). The ancient Mesopotamians had the epic of Gilgamesh, Englishmen of the Middle Age had Robin Hood, and we have Dragon Ball.
The Simpsons seasons 1-8 are one of the two best TV shows ever together with Seinfeld. The later seasons became ever worse and the latest are unwatchable, even worse than Family Guy, which copied the worst from the late Simpsons, and then the latter ended up mimicking the former around. Damn you Mike Scully.
The A-Team was really great. Looking back at it now, they were using the same plot in every episode, almost to the same extent as Bioman, and it was ridiculous how auto-censorship made it so that they were firing weapons all the time but nobody every got hurt. The shots with baddies running while bullets only hit the ground behind them were really iconic, as well as when cars turned over and hit the ground after jumping ten meters up in the air, but there was always a shot of the baddies getting out of it unharmed. But back then it was fun, and when they made special episodes that didn't follow the usual plot, specially the couple of times that they were captured by the military, it was like a feature movie.
I don't think Captain Power was ever aired in Spain. At that time there were no alternative media--and back then in Spain there were only two government-owned TV channels.
I was never a lot into Star Trek. I watched a couple of the Shatner movies on TV, and I remember some of the series but I didn't watch them a lot.
No, I was never a comic nut. I'm sure I would have been if I could, but they were too expensive for my allowance. Specially I missed Marvel, which was very popular with a couple of friends. Still comics were never very widespread in my neck of the woods. I do remember one of the TV shows, I liked it. Later I read some at the public library, and a few more later yet. The ones I would recommend right off the bat are: Ghost in the Shell (the 1st book--and the 1995 movie, both at the peak of the sci-fi genre for any age), XIII, and The League of Extraordinary Gentlemen.
