7 Dragon Fist vs One Punch

Duke used five of his fingers to create five supernova energy bombs to attack Saitama when he was flying away from his kick. Each of the five supernova energy bombs hit Saitama as they flew out from Dukes's five fingers.

In the centre of the multiple mushroom clouds explosions, a fist slammed out pushing all the explosions away. Saitama rushed out of the explosions with his bald head which was reddish in colour due to the explosions.

"Good job !", Saitama shouted out clearly impressed that Duke found a flaw in his fighting style.

Duke rushed out to meet Saitama jumping from the ground causing the ground to crack from his power.

Two parties met in mid air again. Saitama's fist hit Duke's cheeks. Duke's fist hit Saitama's cheeks.

Bang ! Boom ! Bang ! Boom ! Bang ! Boom !

The sound of the fights and continuous explosions could be heard. Both parties figures have disappeared from sight as they moved at the speed of light. The area of their fight have evolved into a vacuum due to the speed and strength both parties fight at. If you are a living being in this area you would have died due to lack of oxygen.

As Saitama was moving at the speed of light he lost sight of Duke's figure, he wondered what tricks Duke was up to. An arm stretched out to Saitama and grabbed his wrist.

Oops !

Saitama was surprised, as he was being held , Duke's other hand converged five supernova energy bombs from his five fingers and directed it at Saitama.

Boom ! Boom ! Boom ! Boom ! Boom !

With multiple successful hits with his supernova energy bomb, Duke jumped back away from Saitama.

Following Duke's actions an extremely dangerous presence could be felt in the air of the dead desert.

From the multiple explosions, Saitama appeared unscathed blowing white smoke which was coming out of his mouth.

The air around the dead desert seem to be shaking with space appearing to be torn in the dead desert.

An invisible pressure appeared in the dead desert.

Saitama's appearance became extremely serious and the excitement in his eyes was overwhelming. Saitama murmured a few unintelligible words as he rushed towards Duke with his hands forming two fists.

At the same time the alarms in the heroes association headquarters would not stop blaring as the staff in the heroes association headquarters was in full panic mode.

Duke looked at Saitama as more Qi in his body converged as he released his second limit, Duke's power level soared again as his whole body is bathed in a white light. Duke rushed towards Saitama as an uncharacteristic smirk appeared in his mouth as his hand concentrated on creating an energy ball.

Duke rushed towards as the energy ball in his hands grew bigger and bigger. Duke appeared next to Saitama as the energy ball in Duke's hands blasted towards Saitama.

Kamehameha !

The most powerful attack learned from Dragon Ball world Duke !

After the energy ball was released by Duke it enveloped Saitama's whole body.

Saitama's last thought was, "Is this the sun ?".

Kamehameha the strongest attack in Dragon Ball world when released caused the dead desert's sand to be melted into glass while the energy blast made the dead desert brighter than day time as the light rushed out from the dead desert causing the other side of the Earth which was night to experience another day time.

A giant mushroom cloud appeared in the dead desert as multiple explosions could be heard.

Boom ! Boom ! Boom !

"Ha ! Ha ! Ha ! Art is an explosion !", Duke laughed happily. The multiple explosions pierced the sky causing the whole Earth to be brighter than the sun for a moment.

The explosion caused the clouds to part in the dead desert.

"No this isn't possible.", Duke said out in disbelief as he looked in the direction of the explosions where Saitama was.

Saitama the bald headed monster descended from the multiple explosions unharmed but almost naked. The only piece of clothing left on him was his tattered underwear which he had protected with his hands. Saitama walked out of the pit that he was buried in.

Saitama looked at Duke calmly with his gold fish eyes.

This time Duke did not wait for Saitama to compose himself, Duke rushed towards Saitama.

Saitama rushed out towards Duke with a serious expression on his face as his speed became faster and faster. Duke released more and more of his limiter becoming stronger and stronger. Both parties moving figure could no longer be seen or heard. They were now moving above the speed of light. Every punch and every kick carried terrifying destructive power enough to destroy the world.

Duke could feel himself getting stronger and stronger as the fight progressed with Saitama. Because of the difference between one punch man world and dragon ball world, the Duke of one punch man world could not become a super Saiyan but high intensity battle could increase Duke's strength continuously.

Saitama punched out his fist but it was caught by Duke. Saitama was surprised, it was the first time in his life that someone could catch his seriously serious punch and was unharmed.

"The last blow Saitama ! We both go all out !", Duke shouted to Saitama.

Saitama nodded his head.

Duke clenched his fist as Qi energy converged in his body condensed into his clenched fist.

"Dragon Fist !", Duke shouted out.

Following Duke's dragon fist who was punching out at Saitama, the space around Duke's fist and arm was torn apart causing ripples in space.

"One Punch !", Saitama shouted out as he punched out as well with his fist.

Dragon Fist vs One Punch !

Which was stronger ?!

As both fist collided, the energy of the explosion was so great the Grand Canyon in the dead desert blew out, the space in the area became distorted and earthquakes roared through the ground around the dead desert and City A. The explosion of the two fist meeting caused another light that was bright it enveloped the whole Earth causing night to become day time again for a moment in the other side of the Earth.

Far away in City A, buildings were collapsing and people were running for their lives. The clouds in City A disappeared. The satellites from the heroes association headquarters directly monitoring the dead desert was destroyed from the explosion.
