Thunder and lightning rained heavily in a multitude of colors as Beerus and I clashed. The location we were in was really close to the edge of universe 7, so in a way we could interfere with universe 6. Another worry would be the break in the barrier between the universes. I assumed that Whis made a barrier because the planet we were fighting on was starting to break. Every clash shook the planet, I remembered when Goku first fought Beerus, Goku had to match or synchronize his exchanges with Beerus to keep the excess of power shockwaves from destroying the universe. Almost every exchange I made sure not let any shockwaves be created for the sake of the universe but the same cannot be said for the barren planet we were on.
Whis: Oya, Sage-san has grown at an extraordinary rate. Beerus-sama is actually using about 80 percent of his strength.
Goku: Only 80 percent?! How much of his strength was he using when he first fought Sage?
Whis: About 60 to 65 percent.
Vegeta: If that's accurate, then even Sage still stands no chance against Beerus.
Whis: That's not true Vegeta-san. I only said that Beerus-sama is using 80 percent but Sage-san is using about the same amount.
Goku & Vegeta: WHAT?!!
After a few more clashes and techniques…
Sage: I'll show you mine if you show me yours.
Beerus: Smartass. Fine, but it's your funeral.
Whis: Ara, it looks like this area might get a little dangerous. Both of you better brace yourselves.
Beerus clenched his fists and briefly closed his eyes as he gave it full strength. Beerus made no transformations because he was being who didn't need to, he simply powered up.
Beerus: Your turn.
I knew Beerus was serious as his smile became similar to mine when I was going for a kill. From the feel of his God Ki, there was a significant difference from how he was fighting with me before and now. Like Beerus, I clenched my fists and closed my eyes. I transformed into my True Saiyan form. I opened my eyes and felt my new found strength. As I internalized all my power I felt different, almost apathetic to the current situation. In the next moment my fur turned from brown to a deep raven black. My muscles tightened and swelled then softened until my optimal amount was met. My hair stayed the same, nothing standing on edge or anything of the sort. After giving myself a look over, I looked at Beerus and returned the same smile.
Beerus: HAHAHAHA!!!! FINALLY!!! A WORTHY OPPONENT!!! Don't disappoint me.
Sage: Right back at you.
In the next moment both of us disappeared and a cataclysmic blast went off causing the barren planet to finally give way and turned to space dust. Whis, Goku and Vegeta were in Whis' barrier bubble a ways away watching the fight.
Vegeta: Same as you.
Whis: Haha, focus your God Ki and follow their traces. Other than eating, this is the first time I have ever seen Beerus-sama so happy. But to think that Sage-san has reached the answer I was trying to teach the both of you on his own.
As Beerus and I were exchanging blows, Whis continued with the explanation.
Whis: The transformations you make from Super Saiyan to Blue is power displayed at a mortal level where you exude energy. Granted, with every transformation there is a significant difference in energy but even then, there is a limit. In order to strengthen your base forms you both didn't need a transformation that shows on the outside, but must come from within.
Vegeta: You say that but why has Sage turned black?
Goku nodded in agreement.
Whis: Sage-san has a multitude of different energies within him, if you think of the energies as colors, what color do you get when you mix all of them together?
Vegeta: (Coming into realization while putting his hand to his temple) Ugh, you get Black!
Whis: Right.
Whis: Both of you can feel the difference in his power, correct?
Goku & Vegeta: Yeah.
Whis: This is what happens when a mortal steps into a higher plane of being. It is not like Super Saiyan Red, Blue or just Migatte no Gokui where you gain a momentay footing into that stage.
Goku: What do you mean by momentary?
Whis: Super Saiyan, no matter the transformation, is very taxing on the stamina of whomever is using it, especially when one first uses the new transformation. If you do not have a grasp of the state, then your stamina will drain that much faster.
Vegeta: Then how is Sage lasting this long against Beerus?
Whis: Oya oya, did Vegeta-san and Goku-san not catch the movements Sage-san made when his fur changed color?
Goku: You mean when he closed his eyes and clenched his fists?
Whis: Percisely. To you his movements were probably just that, but to me he made movements that were so fluid, fast and precise that he grew accustomed to his new state the moment he opened his eyes. (Turning his head) Oya, here comes some spectators.
Since we were so close to the barrier between the universes it didn't take long for Champa and Vados to arrive. Because Beerus was finally using 100 percent of his strength and another being of equal power fighting him, how could they not be curious about who Beerus was fighting?
Between me and Beerus there were no big techniques nor flashy moves. We collided in an old hand to hand combat. Although the amount of surges in energy waves said otherwise. Our power was too strong and I couldn't synchronize with Beerus' attacks to stop them. I had almost no room to spare a thought but because this was not my universe I did not want to destroy it.
Champa: What the f.u.c.k?! Whis! Who the hell is Beerus fighting with?!
Vados: Champa-sama, it appears to be the third Saiyan that fought in the little tournament between you and Beerus-sama.
Champa: WHAT?! HOW CAN HE BE THAT STRONG?!! (Under his breath) He's almost as strong as me.
Vados: Champa-sama, it's not good to lie. Hohoho.
Champa: VADOS!!!
Whis: Nee-sama, were Beerus-sama and Sage-san causing too much of a disturbance?
Vados: Only a bit. A few planets were destroyed but nothing too major. Just in case, I reinforced the barrier wall.
Goku: (Whispering to Vegeta) A few planets she says, and it's still no big deal?
Vados: So Sage-san has finally reached an equilibrium with himself?
Whis: It appears so Nee-sama.
Vados: To think it would be this much though, universe 7 will be stronger during the next tournament of power. Champa-sama, if you continue to laze around you won't be able to keep up with Beerus-sama anymore.
Champa: Why are saying that as if Beerus is going to lose?
Champa turned his head quickly at our fight and came to a sudden realization that he tried to deny.
Champa: You're telling me a mortal is going to beat a GOD?! A MORTAL?!
Vados: Champa-sama, I'm afraid that your current display of knowledge leads me to believe that you are in dire need of training in education and fighting. You can call him a mortal but that does not mean he is one.
