There was quite an age gap between the two brothers. Although Robert was never seen again after about episode 14.
Even Transformers had a shrinking episode. Other recycled stories were the one or two good and bad guys having to team up together to accomplish a common goal/get themselves out of a jam (Starcom, Thundercats, Transformers, G.I Joe and He-Man). And characters either turning really young or old (Transformers, Thundercats, G.I Joe, Ghostbusters, Visionaries and TMNT).
That first one doesn’t really happen in Thundercats. I know it’s sort of meant to be the point of “The Mountain”, but there’s no evidence of any real co-operation.
It does happen in Visionaries though, two or three times.
I used to always call TMNT, TMHT. They changed Ninja to Hero in the UK as ninjas were deemed a bit controversial. The use of martial arts weapons for crime was also not popular in the UK so they edited out a lot of the use of Michelangelo’s nun chucks in the cartoon and the live action movie.
Including the title sequence, when we see the other characters gripping their weapons individually.
Panthro was a victim of this, too - on the few Thundercats VHS tapes I picked up a few years ago, they replaced the clip of him wielding his nunchakus in the title sequence with a clip of him from that episode.
And yes, I remember it as TMHT as well, even now I find myself saying “hero” rather than “ninja”. The interesting thing here is that I saw TMHT and knew they were ninjas before I saw “The Thunder-Cutter”. It was there that I found out that ninjas were baddies . . .
The handicapped character they meet in season two is not hindered by disability. The character is one of the most powerful Earthbenders they encounter…if not the most powerful and gifted Earthbender.
Well, I’ll find out for myself when I get to that episode. Note I say when and not if, I’m pretty much decided on sticking with the series.
