Boreas hadn't a clue how to tell the passage of time here. He tried his best to calculate it with his internal clock. With what he presumed to be minutes, that soon turned into hours. And after that, days. Subsequently, the days became months. Before long, even years began to pass while Boreas's body continued absorbing the growth serum, and kept growing...
It was clear the time Boreas spent inside the growth capsule was far different to how humans grew up, where most only need a couple years before they could start standing on their own two feet. But for humans, they needed to be cared for by other humans. Here, Boreas was all alone.
There was not a single sign of life to be found near the ocean's depths. The Frost Clan was likely residing somewhere much farther away from Boreas's current position.
Crack.
A single crack tore through the sturdy glass of the growth capsule. Crack. Crack.
As Boreas's thoughts stirred once again, the stillness lasted only briefly before he heard a loud crack to strike against his capsule.
'Is it time?', Boreas thought, feeling much more freedom of his body now. He didn't have that floaty feeling. He could move around, somewhat. The growth serum was most, if not all dried up at this point. There was hardly anything left. He didn't realize at first, but Boreas's body grew more than double since he was first placed inside it.
Unbeknownst to Boreas, a full five years passed!
According to the previous two Frost Demons, his initial Battle Power was 500,000. He likely had the highest Battle Power amongst the Frost Clan, perhaps out of most Frost Demons altogether. He was now the current generation, but it was likely the last.
Boreas wondered where his current Battle Power lay. Unbeknownst to him, he would receive his answer sooner than later.
Frost Demons are naturally born with their "final form" state, the last state one would see Frieza use against the Z-Fighters before he goes "Full Power" against Super Saiyan Goku.
That was the same for Boreas. This state, he had 500,000 Battle Power. With the growth serum all absorbed, it was likely much more now. He could feel something smooth flowing throughout his entire body. Just like a river. It didn't stop no matter where it went. Boreas paused, relishing this newfound feeling.
'So this must be Ki that resides in all living things...', Boreas thought. He recalled his faint memories, and felt foreign to this new feeling. He did not know whether or not Ki existed in his past life. He knew that much, that he didn't train in martial arts. But here, his body was experiencing Ki as naturally as breathing in air. Or in this case, breathing in water!
Perhaps that is why this feeling was so smooth? It just felt...natural.
As he thought that, the cracking grew louder and louder. The ocean's pressure was constantly pressing against the capsule. Thanks to the growth serum preventing the capsule from turning into broken glass, it didn't break apart in the past. But it was used up now. There was nothing left to act as a shield against the intense ocean pressure. CRACK!
With one last push, the capsule entirely collapsed, allowing dark water to gush inside, quickly filling what was left up. But the intense pressure broke the capsule's glass, shattering it entirely.
Boreas completely found his body submerged in darkness, the ocean itself. He had yet to take a breath, but a glint of light streaked across his eyes like he had decided on something.
'It is time to find out if the Frost Clan's breathable water trait exists or not...', Boreas thought. He had instinctively held his breath once he was inside this water, because he used to be human. He felt resolved, and let go of his breath.
One moment turned into two, while two moments turned into three...
All Boreas did was blink his eyes. His mouth was moving in and out, still breathing. Water was flowing through it, and was going throughout his entire body, like if it was a natural thing to do. His eyes lit up, experiencing this trait for the first time.
"Neat. This is definitely going to have its advantages. Fights in DBZ destroy its surroundings a lot, lakes and such included. They also fly into various environments. And in those moments, I could have the upper advantage...", Boreas said, speaking aloud this time. Boreas paused, entering a momentary stupor. He realized he had spoken words, and wasn't inside his thought bubble. His voice was quite deep, firm. One typical befitting that of a Frost Demon.
Boreas quickly shook that away, and regained his composure. Looking around, he was all alone. And because he was inside the deep ocean, he couldn't see anything. It was entirely dark. It was then he heard a strong voice strike against his mind. A similar azure glow swept around Boreas's body, which briefly illuminated his being. Shortly after, he heard the voice speak.
"Young Lad, if you are hearing this then luck shone in your favor. Do not seek us out. We were on borrowed time. You are likely the last of our Frost Clan. There are only a few members of the Cold Force left, and they are now living in seclusion.", The firm voice started. It sounded familiar. Boreas realized this voice belonged to the first voice he heard, King Frost!
"And I am sure you are wanting to know what it was that was surrounding your body. That was the specialty of our Frost clan. The Cold Force doesn't know about it. It is with this growth serum that we've been on par with the Cold Force for decades on end, and that damn purple cat just happened to ruin it all.", The voice continued, causing Boreas to chuckle.
'Heh. This voice must be referring to Lord Beerus. Sounds like these Frost Demons had it tough...', Boreas thought. He didn't disturb the voice he was currently hearing. He continued, and what he listened to next surprised Boreas greatly.
"But that's enough of that. You don't need to know what it was, or how it was made. Just know this. This growth serum amplifies a Frost Demon's Battle Power by two or three times, depending on your talent. And I am to believe that you are of the latter, as you are the culmination of our Frost Clan. You should have noticed by now, but your body is now much larger than what it once was. This growth serum tempers our bodies directly. The increase in Battle Power is just a byproduct of that. Unlike those lazy bastards, we grow stronger through training.", The voice continued.
Hearing that, Boreas paused. A three times increase to his battle power...?
Did Boreas hear that right?
"You did not hear me wrong. You were initially assessed at 500,000 Battle Power. If the serum worked as intended, you should now be out of the capsule, and at 1,500,000 Battle Power. This alone should let you live how you want to live without Cold Force's influence. And well, if they come knocking on your doorstep one day, do not be kind. Finish them. Every single one of them is a backstabbing bastard who shows no remorse to who they fight alongside.", The firm voice said, only for its tone to shift, becoming colder.
'That sounds about right. I have no idea why they brought Frieza back of all people...', Boreas thought, acknowledging the voice.
"At the end of the day, this is but a mere recorded message that I had planted on your capsule before you were tossed out into the ocean. By this point, I am likely dead, as the rest of the Frost Clan is. If by some stroke of luck you find our home, you can study our techniques to your heart's content. It is a shame that, as their King, I will not be alive to see you grow. But hopefully, you will carry the will of the Frost Clan, and live on.", The voice said.
It was then the voice turned quiet, and nothing more came out. Boreas was grateful. He wasn't sure if he would carry the Frost Clan name onward, but he was still alive right now. Boreas simply did a silent prayer.
'We may have not known each other, but may you rest in peace.', Boreas thought.
One thing for certain, Boreas was still alive, and that is all that matters.
