Why Goku and Vegeta didnt use Super Saiyan Blue Kaioken and Super Saiyan Blue Evolution to defeat Broly?


So in the new Dragon Ball Super Broly movie,

> Goku and Vegeta try to defeat Broly by fighting together in Super Saiyan
> Blue, but they dont use Super Saiyan Blue Kaioken and Super Saiyan Blue
> Evolution like they did to try to defeat Jiren

Why Goku and Vegeta didnt use Super Saiyan Blue Kaioken and Super Saiyan Blue
Evolution to defeat Broly?




The SSJB + Kaioken Transformation and the SSBE transformation were introduced
by Toei and not Toriyama. Although the movie is being produced by Toei, they
probably have less influence on the movie unlike the show.

Secondly(Note: This is a personal opinion), the movie is mainly focused around
SSJB Gogeta defeating Broly. Hence, having Goku/ Vegeta use SSJB +Kaioken and
SSBE would in a way disturb the flow of the movie. In the sense, it has been
revealed that Gogeta is slowly going to ascend from transformation to
transformation and fight Broly. Having the two additional transformations
would disrupt this flow and at the same time might overscale Broly a little
too high. Plus, if you look back at Goku/ Vegeta vs Merged Zamasu, Goku
doesn't really go Kaioken at all in the Goku Black arc(Despite being
overpowered)(Except the 1 time to break out of Merged Zamasu's hold). Then we
see Vegito Blue in action.
