The fact is exactly what Supreme Kai thought. The transformation into Super Saiyan was just an experiment by Kast. It is not actually Kast's true strength.
As for why there is a slight difference between the Super Saiyan that has just transformed and the Supreme Kai that we saw before, that is because the one that transformed before was not the ordinary Super Saiyan, but the Super Saiyan that surpassed Super Saiyan, which is commonly known as Super Saiyan 2.
Yes, Kast's experiment just now was just to try out the transformation!
As for why the transformation was cancelled, it's because compared to Super Saiyan's transformation, Kast decided to use a transformation that stimulates potential!
After all, unlike the transformation of Super Saiyan, maintaining the state of Super Saiyan places a heavy load on the body, and the combat effectiveness cannot be maintained for a long time.
But if you use a transformation that stimulates your potential, your strength will become solid in the later stage and can be maintained for a long time.
And the body will not be so burdened! Even the strength is even closer!
Thinking of this, Kast no longer hesitated, clenched his hands and exerted force!
Suddenly with a strong impact, Kast completed the stimulation of its potential!
At the moment of 'transformation'! The entire Supreme Kai World was shaking, the ground everywhere cracked, and the hillsides in the distance collapsed! Even the clouds in the sky were attracted by this force, turning into a vortex and gathering above their heads.
Seeing such a terrifying scene, Supreme Kai and others suddenly opened their mouths and were speechless!
But this time, even Old Kai's eyes widened, because the reaction caused by Kast at this time was really too great. Compared with the previous reaction, which was only a local reaction, this time even the entire Supreme Kai World was shaken by this force.
Feeling the power rushing out of his body, Kast smiled. Now he can clearly feel that his strength at this time is hundreds of times different from his previous normal state, and is about 5 or 6 times the strength of his previous transformation Super Saiyan 2!
This power was completely unmatched by him before, and even Kast felt that his strength at this time, even when Son Goku later transformed into Super Saiyan 3, could not compare to him at this time.
After all, Super Saiyan's strength increase of 3 is 4 times that of Super Saiyan 2, but at this time he has completely exceeded this limit, and at this time he is still very strong, and is not in the same explosive state as Super Saiyan 3.
And the potential is not comparable to the potential inspired by Gohan later. After all, Kast at this time ate a lot of divine items, which greatly increased his potential!
In fact, comparing the state of Gohan's potential stimulation and the state of Kast's strength stimulation at this time, we can clearly feel that compared to the stimulation of Gohan's potential, the sense of power produced by Kast at this time is also stronger.
"Okay! So awesome!!"
Looking at Kast at this time, Supreme Kai now finally knows what unimaginable strength is! Because the strength he possesses at this time has made him unable to express it in words.
"Obviously nothing has changed, but at this moment he is exuding a powerful power that surpasses Super Saiyan! This! This is really unbelievable!"
At this time, Old Kai, who was being supported by Supreme Kai and Kibito, heard Shin's words and couldn't help scolding him.
"Idiot! It's not that transformation is a good thing, that thing is evil!"
After listening to Supreme Kai's words, Kibito on the side immediately continued the topic.
"It's really unbelievable! Is this Saiyan!? What a terrifying race!!"
Gradually, as Kast's potential was stimulated, and as the breath on his body slowly calmed down and stabilized, the whole Supreme Kai World also began to stop shaking, so Supreme Kai and others hurriedly walked in the direction of Kast.
Soon, I came to Kast and looked at him as usual. Although he had not transformed into Super Saiyan, the power exuding from his body at this time still made Supreme Kai and others standing next to him feel a strong sense of oppression in their hearts, so they involuntarily took a few steps back and said reluctantly.
"What, how's it going? Mr. Kast, how do you feel now!?"
Hearing this, Kast nodded, but then he saw the depressed Supreme Kai and others, so he restrained his breath, let the breath wrapped around his body be restrained, and then said with a smile.
"Very good!"
Hearing this, Laila on the side looked very happy. At the same time, because Kast had already restrained his breath at this time, he ran over and held Kast's arm.
"That's great Kast! Then you haven't forgotten our agreement, right!?"
Kast looked at Laila beside him and nodded.
"Don't worry! I won't forget."
Hearing Kast's words, Laila's face immediately turned red, but then his eyes were full of happiness.
But Supreme Kai on the side was confused and couldn't figure his head out.
"Promise? Is it worth being the devil Majin Buu?"
But looking at Laila's expression, it didn't seem like this. After all, this incident wouldn't make her look like this, so Supreme Kai asked with doubts.
"Mr. Kast, do you have any other agreements with Sister Laila?"
After hearing Supreme Kai's words, Kast turned around and admitted.
"Yes! But this is a matter between us only. I think that's not what you care about now, right!?"
Hearing this, Supreme Kai suddenly thought of some things that had happened before. He glanced at the two of them and then nodded thoughtfully. He stopped paying attention to this matter and spoke seriously.
"Yes! Mr. Kast, your current strength has completely exceeded the previous limit. Now it is easy to defeat Majin Buu with your strength! So I want you to fulfill the promise between us and help us eliminate the demon Majin Buu!"
