Dan cronus was ment to be different than any other hunter ( hunters are group of people with powers to control the elements, charge with hunting down demons & monsters) with magic, he came from the cronus bloodline. A bloodline that had the ability to control or manipulate anything time, but the downside is only one can exist in a generation. Before Dan there were others Like him who possessed the Cronus bloodline, hunters who had the ability to stop time, some could manipulate space & time to their will in order to travel through time, they were legends, myths, and stories told to young hunters about how great they were... Well except for Dan who only had the power to speed up & slow down his own molecules.
The news came in when everyone least expected the barrier once used as a prison to hold Hidan was no more, Hidan was feared by many hunters, because of how powerful he was, the first hunter to be able to control two elements at once, strong enough to rival a Cronus bloodline. Legend has it that he became corrupt in his quest for more power and made a deal with the demon king, therefore he sold his soul. He brought destruction to the world until Zerd Cronus used his magic to create a space within time it self ( another demision) to seal Hidan, Loosing his life in the process.
The hunters needed all the help they could get, the only Cronus alive was as good as useless, the highest he could do was speed up his body system to degist & eat more food, we are doomed the hunters thought. The best amoung the best has been sent to stop Hidan, but no news. Hidan still under the control of the demon king is trying to release his demon army on earth, and no hunter could stop him.
Dan having left the Cronus estate out of shame heard the news, feeling guity of being usless decide to at least try or die trying. With the help of two other hunters he began his journey, to the tower of gods. ( it is belived gods usually hold meetings here, it is said that the door to the underworld would open at the tower of gods when two powerful elements mix on a blood moon)
Knowing this the hunters had to create an army to save the world, thus the war to save humanity began. Leading the army was the head hunter gray. He lead the army to the valley were the tower of gods stood, the war began, demons were already roaming the earth thanks to the demon kings presence. Gray fought with all his might but the demons were too many, and it seems they would loose, usuing his wind element he created a force field big enough to shield the survivals. When Dan got there he was moved by the pains and death of so many hunters, he increased the speed of his body system allowing him to move almost as fast as the speed of sound, taking down one demon to the other, gray seeing this was impressed on how much Dan has improved ( gray is the only one who actually belives in Dan & loves him like his son ) but the wind shield he created was cracking, the demon ambush was just too much. Dan noticed this and moved to their direction but was stopped by a drakon ( from the family of dragon, they cant fly but can still breath fire) dan with his speed was still not fast enough to avoid a direct hit from the drakon, landing face flat to the ground, he saw his master the only one that ever cared for him get crushed by another drakon. Grey was dead.
Nooooooo! Dan shouted feeling fury like never before, suddenly everything around him stopped moving, no they were still moving but in slow motion, is that even possible? He just slowed down everything around him, moving without thinking he killed everything in sight, but it was still late gray was indeed dead.
From the top of the tower Hidan sensed it, a cronus was here, not a very strong one but his power was growing, fearing this, he sent a dragon.
Dan still feeling guity for the death of gray, saw the dragon come directly at him, speeding up his body system he was able to dodge a direct hit from the dragon. Looking around he saw many of the hunters dead or injured, this needs to end he thought. Moving at speed faster than sound this time he moved towards the direction of the dragon before the dragon could breath fire, he slowed down the time in the atmosphere around the dragon and touch it. In an instant the dragon grew old and turned to dust, he didnt know if it would work but he had no choice, and it did. He was able to manipulate the life span of the dragon by increasing the speed of its growth in an instant.
Hidan saw it happen, he knew the boy's ability he was not just a Cronus bloodline with the ability to control time, the boy was time itself, he could steal time, he needed to be stopped.
Dan now having a better understanding of his powers did not have enough time to celebrate before he saw Hidan coming in all his might, having the ability to control two elements Hidan commanded the earth it self... The grounds began to tear, hunters were being eaten by the earth it self, rocks flying round them crushing anyone in sight, then it rainned, fire falling down like rain Hidan was indeed powerful.
Dan tried slowing time around Hidan, but clearly the demon king was protecting him somehow. He needed to get close to Hidan and touch him, like he did with the dragon. Hidan seeing Dan created a fire tornado crushing anyone in sight and heading straight for Dan.
tapping into his bloodline magic, he shouted, eyes once as blue as the sea became blood red, moving at speed faster than before, ran straight into the fire, the remaining hunters seeing this shouted nooo, but it was too late their only hope disappeared in the fire, then suddenly the fire it self was gone not even a trace of it was left, standing there was Dan.
Hidan saw this and was impressed & at the same time scared, the boy had surpassed his limits. Dan eyes were set on the demon king & his host, what just happened? He actually erased the time around were the fire existed to a time there was no fire. Even his wounds he reversed his body to a time there was no wounds nor pains.
Running straight to Hidan, the fight began, hidan sending fire balls directly to dan using all his powers, dan got close enough and touched Hidan, sensing this the demon king feared it would be trapped forever, forced it way out of Hidan which was exactly what Dan wanted.
As soon as the demon king came out, Dan raised his hands and everything stopped it was Just him and the demon king, it asked who are you? Dan smiled and answered i am Dan Cronos. Bending time it self the demon vanished. Dan created a time were the demon never existed ( in actual sense the demon was sent to a place & time that was not within time)
Dan released time to the way it was, Hidan even without the help of the demon king was still powerful enough to at least fight a Cronos. Before he could take action, Dan touched him, speading up his body and age that he died instantly.
With he cronos powers he reversed time around him and his fallen hunters to a period were they were alive and healthy.
Thus began another legend of Cronus.
