Why Did King Kai Only Teach Goku the Kaioken

Why did King Kai only teach Goku the Kaioken? Turns out, there’s more to the story than you think! King Kai himself couldn’t fully master the technique, and after seeing Goku push it to the limit, he may have been too nervous to teach it to anyone else. But what about Tien? There’s a chance he may have learned a version of the Kaioken to power up his Neo Tri-Beam, which we see him use against Cell!

Use quick cuts of intense scenes, and maybe throw in some humorous moments with King Kai's reactions for fun!

neo tri beam uses his life force, in raging blast and other games, the more you blast the more health it takes

Lets not forget he can duplicate any move he sees by seeing it once or twice.

Cell: ...and Tien...

Are we forgetting about the spirit bomb goku's strongest technique he also learned it from king kai

[BigJake]

thats a bit of a stretch. The kikoho used life energy to amplify ki. Kaioken boosted the users ki at the cost of a greater physical toll on the body, but didn't utilize life energy.
