Tenshinhan's body sustained shin kikoho who is stronger than kaioken.JulieYBM wrote:Yes, but Saiyan bodies are strronger than human ones, eventually they're going to crash, not to mention they couldn't possibly use a x50 times Kaiô-ken quickly.
Anyway,i don't think Tenshinhan was a regular human at least according to daizenshuu,but that's another story.
Too obvious.A god whose fighting skills are weaker than Nappa`s (who is below a 8000 power level) despite having centuries to train.
I think its safe to assume that kaio`s fighting potential is not that good or as high as the sayans or the humans fighters who visited him.
Who knows if kaioken principles were the base to make shin kikoho.I don`t see any reason to why Tenshinhan couldn`t have learned it if he was the one who stayed the longest with Kaio.
After all, he said that he would mix kaio's techniques with his own.
Tenshinhan and the others overcame gravity even faster than goku,so... Tenshinhan had the conditions and the time to learn the technique."He quickly overcame this planet's gravity... He really is as great as I'd hoped... And still 118 days remaining! He may be the one who can master the Kaio-Ken! The Kaio-Ken that I have yearned of, but could never master myself! Oh, for that final attack!"
