On a village in a small corner of India couple was afraid, they were very much afraid as they looked at their first and only child, adopted as he might be. His hair was as white as snow and his eyes were a light blue near green, his features were naturally sharp but still pretty enough.

The child in question was playing with his toys but the couple did not seem to register the innocence in the boy and instead focused on the other thing, the fact that he had a staff of his own size on his back that had just came to him out of nowhere together with two more items. A body-suit like armor that covers his entire body while also wearing great earrings that looked to be made of gold. And he also had bow and arrow on his hips that looked to be for his size but emanated danger all the same.

All of it came out of quite literal nowhere for the humans in question while the Demi-God that brought them was on the air looking at his parents with concern. He had just fulfilled his long promise to his rival after fending off the Gods and others who wanted the weapons that were entrusted to him had returned to the rightful owner even if the spear was not to be as he had to give it back to the God who owned it as it was just lent in the first place.

Sighing he shook his head, he had not given the spear back but at least a staff of equal value should be worth something.

"I hope that this life does you better, my eternal rival and that we can once more cross paths but this time as allies." The Demi-God said before coughing in his hand, seeing the blood in it as he looked at the horizon.

As he looked at the young reincarnation of his eternal rival he thought of the blood on his hands from a simple cough and the wrinkles that now adorned his once handsome face.

"Age, such a dreadful thing indeed. It makes me wonder if me killing you back then was a terrible act or one of mercy." Chuckling to himself the Demi-God continued as if talking to his friend. "I guess it is time, after all, you might be young but I am not, I would be too ashamed to appear before you as I am so instead I have other plans. You will not be the same Karna I once knew nor will I be the same Arjuna, let's let our descendants be the ones to decide how our destinies will play out in the future." Arjuna thought to himself as the demi-god searched the globe for the person who had his blood and was the most perfect match for what he intended to do.

Locating the said person was easy but it left a wry smile on his face as the person in question ended up being the neighbor of Karna's own family, the daughter to be precise who was currently close to dying on her sleep due to the poison of a snake that entered the house without the parents realizing a thing. It truly is destiny playing with him just like it always did.

"I guess this time destiny is playing with me instead of you my rival, interesting, truly interesting." Arjuna said as he started turning to dust, his body had long since given out and he only stood strong due to him using his powers to delay the inevitable, but this condition was one he would not accept.

He would never be able to face his rival, or his descendant in this case, with being in such a weakened state as the more time passes the weaker he got. If so he would choose to be like his rival, living a new life in a new body and experiencing life anew.

His soul entered the body of his dying descendant as his weapons started going to her. However, before he went fully, he sent one last message for an old friend of his.

"Wukong, I want you to look after two kids for me, they are on Kamak Village in east India and will need your help. Do this as a last favor for an old friend." Arjuna sent this message before the process completed.

Sun Wukong, the Sage Equal Heavens, heard it loud and clear before sighing as another one of his old friends passed away, the least he could do is go and fulfill the last request of his friend, not like he hadn't helped him before as he now had to use a mere copy of his original staff instead of the original that he had given Arjuna.

"At least it is better than to give it to the snotty brat of my house, to think that Biko is the one that was most suited for it makes my old bones annoyed already." Sun Wukong said before jumping up as a cloud came to him before anyone could see where it came from.

Back on the village, the young boy looked at his parents' terrified expression and he could see the fear on their eyes. They were afraid of him even if he didn't do anything, he just talked to some old man a while before who had appeared out of nowhere and that gave him these weapons he now was carrying on his body.

They all felt natural to him even if he would admit that he didn't felt just the same for the staff, but it was a gift and as such he would not deny the old man's wishes for him to have them.

The boy then heard something, it was like a voice on his head that started talking to him.

'Myself, you should feel grateful for the gifts bestowed upon you. If he gave you such gifts then he knows who we are, it is not safe to be here as soon those who would hurt your parents will appear as others realize who we are. So, I shall bestow upon you a gift to help in your protection before we can't contact each other again.' The voice said this was the last vestiges of his previous life that surged with the contact with a strong stimulus like the presence of his rival and the weapons he had recovered. But this was only a temporary situation at best and after it, the voice would fully integrate with the soul and the new life would begin properly. 'I unlock our potential as descendants of Surya, the power of the Sun is now ours to use and to protect those who need. Use it when you deem fit, and if you ever meet my rival try and not make him your enemy as I did on my time, he is a scary one but also probably the best one you can ever find, also if possible try and know him well. I felt it, on our last encounter, how he is actually someone who is sad inside and carry too much on his shoulders, just too much.'

That would be the last time the 'voice' spoke to the young boy named Karna, the rebirth of the Hero of Charity Karna, one of the most legendary and strongest heroes to ever walk earth.

As Karna wondered what to do he saw a golden cloud in the distance when he felt warm in his right eye before the cloud nearly being vaporized as a bean of fire launched from the eye without any control from the boy.

Sun Wukong, who nearly died then and there (the power of Brahmastra was not to be underestimated) sighed in relief in how he managed to escape in time. He would have some choice words with whoever did just that, already figuring out that it was likely one of the kids that Arjuna asked him to watch over.

However, he did not expect to, right after, a white light appeared where he stood and the fur on his whole body stood on end as he aimed his staff to the ground.

"Expand Yeoui." he said and the staff on his hand expended, sending him flying high and away from the attack. "Damn snotty kids trying to kill me." He said and just as he was about to go see the two he saw a colossus coming in his direction, one he identified well enough as he had given it to Arjuna not long ago.

"Fuck. My. Luck!" Sun Wukong said as the original Yeoui, also known as Ruyi Jingu, came to him in quick expansion due to his own orders (he did tell it to expand and even if it had a new owner the weapon would obey him for a while yet) and it didn't grow only in extension but also in grit as it now was of the same radius as the size of a small mountain and it hit him right where it hurt.

But, even so, Sun Wukong could only laugh.

Yes, this is what he wanted, those who might be able to receive his heritage completely as he could not make Biko be the one as it just was not into his bones to be able to be taught, he had his own destiny to follow and his own path. But these two, he recognized what was the likely situation and it could only make him laugh, he might not have his descendant to teach all he knew but he had the next best thing, two heroic descendants of two of the strongest heroes to ever live and with the souls of their ancestors in full power no less.

Yes, he could work with this very well.
