The Siayan and the Cat girl (Goku x Bagi) (DBZ x Osamu Tezuka)

Kisame

A few days had passed after their first training session with the melon god. Goku and Bagi had grown stronger because they were training with an even stronger being. 

Goku(Base) - 3,000

Goku(Powerstar)15x - 45,000

Bagi(Base) - 3,000

Bagi(Powerstar)15x - 45,000

Goku and Bagi were again training with Melony yet again. This time, Axol was watching his girlfriend use her B rank jutsus against the two now more stronger teens. Mario walks in and looks at Axol.

Mario: Why don't you train with them, Axol.

Axol: No thanks. I'm already getting started on learning magic once Gandalf comes here.

Mario: I heard he's going to come any day now. 

However, this is the day the Neo Akatsuki would launch their attack on this world. 

An hour later at the SMG house

Melony: If you want, I can help you two learn about chakra and take you to Konoha.

Bagi: That sounds like a good idea.

The TV then began to show Villager News and a minecraft villager at the news desk.

Villager #4: Breaking news! The city is being under attack by an unknown force that seems to be coming from an airship of sorts. Villager #9 is on the scene as we speak.

It then cuts to Villager #9 at a scene of chaos.

Villager #9: Thank you, Villager #4. I am standing here amidst the chaos that is ensuing here in the streets. Two figures who are identified as the infamous Dr.Eggman and a sharkman of sorts named Kisame Hoshigaki.

Goku: Hey, these guys might be with Bowser!

Bagi: We gotta tell the others!

At the streets of Gmod city

The Tarkatans rampaged through the streets along with the mist shinobi and the egg doctor riding in his eggmobile. 

Eggman: Soon, we'll take our forces to city hall and declare our takeover of this city. 

Eggman's robot version of Sonic, Metal Sonic, agreed with him.

Kisame then senses a huge amount of chakra coming towards them.

Kisame: A chakra user? Here?

Then a blue blur zooms in taking down several tarkatans and then right towards Eggman.

Sonic: This ends here, Egghead!

Eggman: Ha! That's what you think, Sonic the hedgehog. Metal Sonic, destroy him!

Metal Sonic: Combat mode engage!

Metal Sonic charges towards Sonic only to be hit with a cannonball coming from a flying ship that came out of nowhere. The Black Pearl had come with reinforcements. 

Jack: Ahoy, Mateys!

Eggman: Jack Sparrow?!

Jack: Captain! Captain Jack Sparrow!

As soon as the ship touches down, Jack's pirate crew comes out to fight the Outworld army. Wolverine leaps from the ship snagging a few tarkatans with his adamantium claws. Sam and Kaizo with their own weapons came in cutting through the army along with Knuckles and Donkey Kong as the vanguard. 

Kisame smiles as he had thoughts of how he could quickly dispose of them all. That train of thought was interrupted by a punch in the face by none other than Son Goku who came along with Melony and Bagi.

Kisame looked at Goku and at Bagi. He was confused and angry at the same time.

Kisame: These are the Chosen Ones?! A Saiyan kid and a Cat girl?!

Goku: What was that?

Kisame realizes that Goku was not aware about his true origins. He smiles as he was about to reveal his true origin until his Neo Akatsuki ring rendered him from telling Goku. Kars used his telepathy to talk to Kisame.

Kars: I shall be the one to tell him. IF he survives this attack.

Kisame: Nng...Yes...Lord Kars.

Goku: Who's this cars guy?

Kisame: His name is Kars. HE is the true mastermind of our Grand Plan.

Bagi: So it isn't Bowser who's behind all this.

Kisame: Bowser is a member of our organization. We are the Neo Akatsuki!

Goku and Bagi with this information now realize that they were in a much larger plot at play here.

Kisame: Now that you know, YOU! WILL! DIE!

Melony: I don't think so, sharkface!

Melony VS. Kisame

Round 1 FIGHT!

Both the Samehada and the Deity sword clash as a huge shockwave affected the entire battlefield. 

Kisame: Nice sword. Once I'm done with you, I'll take that sword from you and use it to bring my own world to its knees. 

Melody: Only if you take me down first.

Kisame and Melony, both masters of Kenjutsu, were on par as each sword clash send small shockwaves and with another sword struggle, Melony uses her lightning shadow clone technique to take Kisame by surprise. kisame however was well aware and jumped up and used his Samehada to summon a few water sharks down upon Melony and her shadow clone. She use her swordbeam to disperse the sharks and then aims at KIsame but was already gone.

Kisame appears from behind and goes for a punch. Melony blocks the punch and uses her lightning ball jutsu to blast Kisame off. He lands on his feet and uses his water clone technique to summon two of himself. 

Kisame: Take this! *Uses his handsigns* Water prison technique!

Kisame and his shadow clones shot out three large water balls aimed not at Melony, but at Goku and Bagi.

Melony: NO!

Melony and her shadow clone get in front of the water balls and use their swordbeams to disperse the two water balls with the last one the shadow clone jumped in front of to sacrifice itself. Kisame smirks at her clever move.

Kisame: So. Why don't you use your Fierce Deity form already.

Melony: Oh I will. But first...

She pulls out two powerstars to give to Goku and Bagi. Their power levels increased by 15 times. Kisame looked shock at the two's increasing power.

Kisame: Hmph. Such power. Wild water wave!

He spews out a large amount of water at the three heroes. The Fierce Deity, and the two chosen ones in their powerstar forms were able to tank the attack. Kisame was shocked as he tried to use his Samehada but was punch by all three of them. He flies away from the punch as a certain King saw it all in his own eyes.

???: Hmm. They might be fun.
