Strawhat's Saiyan

Training begins!

Goku charges at Roger and swings his staff at him but the Pirate King dodges and kicks Goku very hard. "Hehehe... He sure does kick very hard." Goku said as he got back up. "My hands are shaking in excitement." He says. Oden pulls out his two swords and runs toward Goku.

"Son Goku prepare yourself for my attack!" Oden yelled. "Nintoryu Paradise Waterfall!" He shouted as he cut through Goku's gi. The saiyan didn't have time to dodge the attack from the samurai. "A little closer and I would have a scar on my chest." Goku told himself as he removed his top weighted gi.

"Gurarararara!" Whitebeard bellowed. "Son Goku you avoided Oden's attack... Now it's my turn." Whitebeard told the saiyan. 'Oh shit!' Goku thought to himself. Newgate held his fist... which began to glow white. Goku moved out of the way and just in time from getting hit by Whitebeard's earth-shaking punch. Still the impact caused the ground to shake.

"Try some of this!" Goku screamed as he fires his ki blasts at Whitebeard. Newgate takes the ki blasts and dust covers the old warrior.

Goku stops firing ki blasts and tries to see if Whitebeard got taken any damage by it. As the dust clears Whitebeard jumps up in the air and pulls out his halberd (bisento), the blade glowing white.

"Eat THIS!" Whitebeard roared as he slammed himself on the ground and the blade into the ground creating a huge tremor that caused a huge shake on the dimension, and Goku was hit head-on by the force!

"AAAAAAAGH!" Goku screamed as he was sent rolling across the ground. "Damn they really are the strongest." He said, "But let's see you three handle this!" Goku yelled as he releases his ki. 

He starts firing ki blasts at Roger, Whitebeard, and Oden. He then rushed towards at Oden and kicks the samurai and removes Oden's weapons from Oden.

"Let's see how you do without your swords! Here I come! Now it's my turn!" Goku said as he charges at the opponent and elbows them away. Then, he attacks the Oden with a powerful barrage of kicks and punches, ending with a heavy punch to their stomach.

Oden lies on the ground paralyzed; Goku jumps up in the air and shouts. "Ka... me... ha... me... Ha!" and he fires a Super Kamehameha down at his opponent, inflicting a massive amount of damage.

"One down! Two more to go!" Goku says. Goku creates a razor-sharp disc of ki from his palm. He throws the disc at Roger which was a distraction. Goku teleports in front of Roger and attacks with a strong left punch. He then attacks the samurai with several high-speed punches and kicks. Goku finishes the attack by knocking Roger away with a left-hook kick, inflicting a huge amount of damage.

"Just you and me Whitebeard!" The saiyan shouted as he fires multiple one-handed Kamehamehas from both hands, inflicting a great deal of damage to Whitebeard.

Goku stopped his attack and was panting really hard. "How's that?!" Goku said.

Whitebeard directly cracks the air in front of Goku, causing severe damage as the shockwaves directly pass through the saiyan's body, as Goku suffered.

Goku tried to get up but he couldn't. 'I have to be more careful fighting them! One little mess up and I'm a goner!' Goku thought as he saw Whitebeard grabbed the two swords and throws it at the samurai. "Oden catch!" Newgate yelled. Oden catches his swords and smiles. "Thanks captain."

 Oden crosses his swords and charges forward, slicing Goku in his path. "Gun Modoki!" Goku gets a mark on his arm.

Roger was waking up and saw Whitebeard and Oden attacking Goku.

Goku then fires flurries of large bright ki blasts at Roger. The waves themselves just chase Roger. But Roger uses Busoshoku Haki. He imbues his saber with the Haki, allowing it to evenly clash against the ki blasts.
