This story takes place after Dragon Ball Z series ended, and 6 months after Sōsuke Aizen Betray the Soul Society.
"Call Head Captain Yamamoto since Arturo Plateado has appeared in the human world along with Grimmjow Jaegerjaquez and Coyote Starrk" a messager said.
Later at Captain Meeting.
"Head Captain Yamamoto what are we gonna do about Arturo Plateado, Grimmjow Jaegerjaquez and Coyote Starrk that they are in the world of living" said Captain Hitsugaya.
"I'm going to send 3 captains and 2 Lieutenants" said Head Captain Yamamoto.
"Who might they be?" Ukitake asked.
"The Captain's are Byakuya Kuchiki, Shunsui Kyōraku, and Kenpachi Zaraki and the Lieutenant's are Shūhei Hisagi and Rangiku Matsumoto, also Kudo Twins Fujimaru Kudo, Matsuri Kudo will go to the world of the living Head" Captain Yamamoto said.
"So is it at Karakura Town" Captain Hitsugaya said.
"No it's at Ginger town Head" Captain Yamamoto said.
"Isn't that located near West City where Cell when he was still absorbing from the human's energy?" Captain Kyōraku asked.
"Correct" Head Captain Yamamoto said.
At Ginger town.
"So Arturo the humans can't see us right?" Grimmjow questioned.
"We are in the world of the Living so highly unlikely" Grimmjow Starrk said uninterested.
"Let's get this over with" Arturo said with no patient.
Suddenly two men appeared in front of Arturo Plateado,
Grimmjow Jaegerjaquez and Coyote Starrk before they could blink.
The first one wearing an orange gi width a blue shirt underneath and he has an orange pants and the second guy wearing an blue jacket with an orange circle on his back with the word "wisdom" in Kanji writing in the circle.
Who are you two dead man? Grimmjow asked.
"I'm Goku and this is my Son Gokenku and I can tell you 3 are very strong so Gokenku should we power up" the man named Goku said.
"Yeah" Gokenku said.
"Huh power up?" Grimmjow asked.
"Yeah you'll see in a few sec's" Goku said.
Then Goku & Gokenku began to power up.
"Ahhh" said Goku as to change.
"First Goku & Gokenku eyes turns from black to Turquoise then their went straight up and turned Golden colored, then Goku & Gokenku went to go to the next level to Super Saiyan, Super Saiyan 2 their strength and speed increases and Lightning begins to surround their body."
"What exactly are they?" Grimmjow asked.
"I never heard of this before and they don't seem to be Soul reaper's" Arturo said.
"Sorry for the wait" Goku said.
"Yeah now we are ready" Gokenku said.
At Captain Kyōraku location.
"We got to hurry I don't know how long the city is going to be in one piece" Matsuri said.
"Yeah since there are 3 Arrancar Espada there we got to hurry then" Captain Kyōraku said.
Back at Ginger town.
"You two can get the first hit on me" Arturo said.
"Fine then" Goku said.
Goku & Gokenku shouted "Ka...Me...Ha...Me...Ha...!" The Kamehameha wave that Goku & Gokenku shot at Arturo and took him down on one knee.
"Arturo! We will take those two Both" Grimmjow and Starrk said.
"Fine" Arturo said as he realized that they are stronger than he originally thought.
"Your Mine Goku I should be more than enough" Starrk said.
"We see" Goku said.
"Yeah we'll see won't we" Starrk said.
"Gokenku I'm gonna destroy you" Grimmjow said.
"Just then the Soul reapers that Head Captain Yamamoto sent to the world of the Living arrived."
"Huh there is not one building damaged" Fujimaru Kudo said.
"Why is that?" Matsuri asked.
"Maybe cause those two with the golden hair arrived before we did and I think that's why nothing was damaged" Captain Kuchiki said.
"Captain Zaraki Arturo is down on one knee" Matsumoto said.
"Those two must be very strong then what is their Spiritual pressure?" Zaraki asked with a big grin.
"Yay Kenny is in good mood cause you found a strong fighter huh Kenny" Yachiru said.
"Yeah that's right Yachiru" Zaraki said.
Back with Goku.
"You might be putting more than you can handle" Goku said.
Starrk pulls out his Zanpakutō.
"Ok then "Kick About" Los Lobos" Starrk said.
"First his upper body is covered in a grey fur-lined jacket over a double-breasted vest then his legs are covered in some kind of dark skin-tight pants with grey knee-high fur leggings covering his lower legs and finally his arms are covered in some kind of gray elbow-length fur armbands that appears to end at his wrists."
"Let see you take this Ka...Me...Ha...Me...Ha" Goku said as he fires the Kamehameha wave shot at Starrk but he deflected it like it was nothing.
"Dam I'll try one more time Ka...Me...Ha...Me...Ha" Goku said.
"it won't work" Starrk said.
"Goku used Instant Transmission with a Kamehameha to vanish from Starrk sight and reappear in front of Starrk and blast a Kamehameha at full blast."
"Dam huff...huff...huff... I need to stop him" Starrk said weaken by the Kamehameha wave.
With Gokenku.
"My father is stronger than me but you still might be putting more than you can handle" Gokenku said.
Grimmjow pulls out his Zanpakutō.
"Ok then "Grind"" Pantera Grimmjow said.
"First his teeth become jagged and sharp, then his hands turn into black claws and his feet become black clawed paws, similar to that of a cat, along with a slender whip-like tail. His hair becomes very long and flowing, and the markings around his eyes enlarge and extend to the tips of his ears, which become cat-like. He loses his distinctive jaw mask, which is replaced by a sort of a headgear on his forehead."
"Your mine" Grimmjow said as he went to attack Gokenku with a Cero.
"Yikes Ka...Me...Ha...Me...Ha" Gokenku said as he launches a Kamehameha wave to delay the Cero.
"Your attack will not go through mine" Grimmjow said as Gokenku's Kamehameha wave did go through Grimmjow's Cero.
From behind Grimmjow came Captain Kyōraku to help Gokenku.
"Who are you?" Gokenku asked.
"I'm Shunsui Kyōraku Captain of the 8th Division in the 13 Court Guard Squads."
"Ok I don't mind the help but don't get in my way" Gokenku said.
"Don't worry about that Captain" Kyōraku said.
"So a Captain came to help this worm huh doesn't matter who helps you I'll still win" Grimmjow said.
"Oh yeah Captain" Kyōraku said.
Captain Kyōraku pulls out his two Zanpakutō.
"Flower Wind Rage and Flower God Roar, Heavenly Wind Rage and Heavenly Demon Sneer" Katen Kyōkotsu Captain Kyōraku said.
Captain Kyōraku attacked Grimmjow but Grimmjow use a Cero at full blast with both of Captain Kyōraku swords were enough to stop a full blast Cero.
With Goku.
"You won't defeat me" Starrk said.
"It's time I get serious" Goku said.
"Serious?" Starrk asked.
"Yes time to go to my full power" Goku said.
"Fine I'll still beat you" Starrk said.
"Goku began to go to his super Saiyan 3 form His hair begins to grown down his back and his eyebrows disappear. Lightning begins to surround his body increases the raw power and speed."
"Starrk used Sonído to try to get behind Goku but Goku proofs to be too fast for Starrk. Ka...Me...Ha...Me...Ha Goku said as he fires his Kamehameha wave at Starrk."
"I don't think so" Starrk said as he fires a Cero at full blast but Goku Kamehameha wave still went though but it was weaken due to Starrk Cero.
"Ahhhh it hurts" Starrk said.
"You just delayed your defeat" Goku said.
"I didn't imagine you would be this strong and your speed to change so drastically" Starrk said while trying to catch his breath.
With Gokenku.
"This "Grimmjow" is quite strong but what's with the #6 on him" Gokenku said.
"Oh you don't know who I am well Arrancar #6 Grimmjow Jaegerjaquez."
Gokenku puts the hands up to the face and shouts Solar Flare shouted Gokenku.
"The light reflected into the Grimmjow's eyes and thus blinding him."
"Now Captain Kyōraku strike now while he blinded" Gokenku said.
"Right" Captain Kyōraku said.
"Ka...Me...Ha...Me...Ha...!" Gokenku launch a Kamehameha wave at Grimmjow and Captain Kyōraku strikes him with Bushō Koma and with the two attacks Grimmjow falls to the ground due to Captain Kyōraku's Bushō Koma and Gokenku's Kamehameha wave.
With Arturo.
"Weakling Grimmjow I should of known of bring the Arrancar #6" said Arturo.
"We're your opponent" Matsuri said.
"Yeah that's right" Fujimaru said.
"Two flea's fighting me now huh" said Arturo.
"I'm no flea Bankai" Matsuri said.
"Matsuri has a dragon head on her left shoulder and a cape on her waist to foot and on her right shoulder is a piece of gray fur and her blade itself also seems to be composed of a bright pink energy."
"I'm no flea also Bankai" Fujimari said.
"Fujimari gains a tiger head on his right shoulder and a cape on his waist to foot and on his left shoulder is a piece of gray fur and his blade is composed purely of blue energy"
