Kale and her repressed manner along with her emotional outburst are remnants of the original Broly. But her "intimate" relationship with Caulifla gives weight and purpose to all of this, achieving a culmination of the development arc of the two characters fighting together for survival. That seems different, doesn't it?
However, the Dragon Ball Super TV series felt the need to visually reinforce the influence of the original Broly, adding that gigantic transformation with greenish hair, making it more than clear to everyone that this is the "female Broly".
Well, apparently, it's the same transformation. So does that mean that Kale is the legendary Super Saiyan? No. They are two different forms! Confusing, right?
In fact, it is the "Super Saiyan Berserk", which was introduced in episode 93, impressing Caulifla and Cabba, who did not understand the extent of Kale's strength. This is repeated in episode 100, which would be a much more appropriate time to reveal this enormous power without it seeming like a repeat.
In the following episode, Kale would end up awakening her traditional Super Saiyan form, which looks nothing like the yellow-haired one, sounding more like the controlled Super Saiyan Berserk.
However, this is not the case. Kale would only control Super Saiyan Berserk in episode 114 after losing control for the fourth time (!).
Not only is the order of the transformations messed up, but it also seems like a repetition after repetition of the emotional beats in her character arc.
Toyotarō's manga adaptation also has its own version of Kale, fixing (partially) these problems I mentioned.
There is no repetition of the same emotional beats, and Kale only has one transformation. Is this the traditional Super Saiyan? Probably not.
Based on the colored edition, it seems to follow the same concept as Super Saiyan Berserk, but visually different from the animated version.
So, does this mean that Kale doesn't have a traditional Super Saiyan form like Caulifla, Cabba, Goku, Vegeta, and the others? And if she does later, will she only have it after she learned Super Saiyan Berserk, which is more powerful? It seems like an unnecessary complication...
And so, one year after Kale's appearance in Dragon Ball Super, Akira Toriyama presents his revamped version of Broly, which has no relation to her.
Toriyama understands that we don't need a specific form to portray the character's emotional out of control. He's already essentially like that since his base form. Here, he simply transforms into the traditional yellow-haired Super Saiyan that we all know, serving as a turning point for the character and making him more powerful. That's it. That's enough.
However, once again, the film's production found a way to include the muscular, green-haired transformation without any dramatic weight, sounding unnecessary and reducing, once again confusing fans.
No, this is not the legendary Super Saiyan form first seen in the original 1993 film. This is the Super Saiyan Full Power (?).
So, what do I think it should be?
Use Toriyama's approach for both. Kale and Broly are emotionally out of control characters from the beginning. You don't need another way to convey this change. Just use Super Saiyan as a trigger, making them more powerful, and then work on emotional control based on their relationship with their supporting characters. Simple.
By the way, the colors chosen for the colored edition of the manga simply irritate me (in the TV series it's also problematic): Kefla's hair color has nothing to do with Kale and Caulifla's!
Besides, everyone knows that Kefla looks much cooler (and more consistent) as a blonde!
