Ok, Let Me Talk About Shin Asuka, Then ...
Well, since
someone (*cough* KingRanger *cough*) has insisted we keep this to strictly Japanese programs ...
Every Ultraman, whether Ultra or human host, have ended up with happy endings. All that is, but one ... Shin Asuka, Ultraman Dyna.
I was pretty upset with the ugly way his show ended, with all the ways he got killed off at the end.
Yes,
ways.
Plural.
[HIDE]1) First, foremost, and quite simply, the worst: He is betrayed and murdered in cold blood by members of the human race he saved so many times. People who wanted to steal the power of Dyna, allegedly in the name of humanity. And, were quite willing to hold hostages to force him to submit to their experiment... Worst of all, the villians go unpunished for their crimes.
2) After being apparently revived by his Ultraman partner, Shin gets "blown up" defeating the "Frankenstein" Ultraman that the villian had stolen his life force to create - and which had gotten promptly hi-jacked by the Spheres, the
real invaders.
3) And, finally, he vanishes down a "black hole" created by the GranSphere's death throes. We get a final mystic vision showing Shin waking up in his ship - and catching up to his long-lost dead father, going side by side into the light of the AfterLife. For some reason, we're supposed to think that he's being taken to Ultra and will return in the future. But, we never see that happen.[/HIDE]
Not to mention the various ways he got the short end of the stick thereafter ...
[HIDE]A few years later, after the first Heisei Ultra period had ended, just before Cosmos launches, we get several direct-to-DVD movies, giving new stories for Tiga, Dyna, and Gaia/Agul. For Tiga, and Gaia/Agul, we get stories showing new adventures set in the future. For Dyna, we get what seems to be a story that ignores those last three episodes, but doesn't say whether it's Alternative Universe (AU) story - or a universe that was visited by Sam Beckett* ...
Then, just over ten years after that final episode of Dyna, we get an AU Shin, Daigo, and Gamu, in Super 8 Ultra Brothers- who eventually become Dyna, Tiga, and Gaia. It was great seeing Shin again, even an AU one. But, did they really have to
humiliate him by making him a
batboy, not just a minor league baseball player?!

Don't get me wrong - it was great seeing him alive and well, in a relatively peaceful and happy life with his two
new childhood
best friends. However, that didn't mitigate the tragic ending of the
real Shin Asuka ..
... Until the next year, in Ultra Galaxy Legend, we do see that the
real Shin Asuka is indeed alive and well, apparently residing on Ultra in the Showa Universe. My main complaint is that the writers never gave even a brief explanation for his survival, nor his prescence in the Showa Universe. It was almost as if they didn't want to acknowledge how
big of a game-changer this was. Or, worse yet, were just
using the character to draw in the fans.
*Sam Beckett is the time-travelling hero of the American
"toku" series
Quantum Leap, who went all over time in his past "setting right what had once gone wrong". He only failed
once. But, it was a very
big once.
[/HIDE]Bottom line, it was a cruel ending for a rather charming character that went directly against the hope and optimism of the Ultra series.
