The man was in an unfamiliar place.

The woman woke up, not knowing where she was.

Where am I? The man thought in his basic language of Japanese.

How did I get here? The girl thought in English.

He appeared to be in an arena of some sort. An ancient arena.

She was amazed at the ruins; how beautiful they were now.

And then, one saw the other.

Wow, he looks pretty strong! She thought. But where's his weapon? Doesn't he need one to fight?

Woah! I haven't seen a warrior like that before! He thought. Smirking, he got into a battle position. She'll make a great training partner!

Huh? Looks like he wants to fight. She readied her scythe. Alright then, it's his funeral.

And thus, the fight of the ages, between the Silver-Eyed Huntress, Ruby Rose, and the Saiyan Raised On Earth, Son Goku, began.

"HAAAAAHHHHHHH!"

"TSYAAAAAAAAHHHHHHHHHH!"

Crescent Rose collided with fist, the battle off to an epic start! Between swings, punches, and kicks, attacks were dodged either with the Speed Semblance or Instant Transmission. Multiple twirls of the scythe blocked each rapid punch and kick.

"NNNNNGGGHHHH!"

"DADADADADADADADADADA!"

The force was enough to send the two flying to opposite sides of the Coliseum. As Ruby reloaded, Goku prepared his next attack.

"Ka…."

"Me…."

As blue energy formed in his hands, Ruby charged up her speed.

"Ha….."

"Me…"

Within the same second, both unleashed their power.

"IT'S OVEEEERRRR!"

"HAAAAAAAAAAAA!"

The red streak collided with the blue energy beam, causing a struggle.

"Kkkkgggggghhhhh…. KAIOKEN!"

The increase of power broke the struggle, yet Ruby recovered.

"Ha!"

"YAH!"

Ruby managed to hit Goku in the chest with the back of Crescent Rose, making him cough up blood and sent him flying.

She's really amazing. He thought. Time to kick things up a notch!

He began to scream, as Ruby noticed small debris begin to rise.

"What the-?"

"HAAAAAAAAAAAAAAAAAAAAA!"

As the dust settled, Ruby saw her opponent now flying and with golden hair.

Alright, Goku thought. Let's see how she handles against a Super Saiyan!

As the two clashed yet again, Ruby found herself at a slight disadvantage.

He's getting stronger! She thought. How can one guy get so powerful when he doesn't have a weapon?!

After skidding backwards, Ruby began firing Fire Dust Bullets at him…

But Goku only dodged some, knocked back others, and even caught and crushed one!

She's pretty good. But now it's time to get serious! Time to go Super Saiyan 3!

After transforming, Goku leaped into the air and began to channel his energy.

Let's see her handle this! The power of a Spirit Bomb!

He threw the large sphere, which remained its course no matter how much bullets hit it. As it closed in, Ruby realized she had just one trick left. She concentrated, then released the power within her!

"Nani?!"

As the Spirit Bomb was destroyed, Ruby emerged, her silver eyes now glowing with energy.

Heh! She's not the only power player!

Goku transformed yet again, this time all the way to Super Saiyan Blue! She may have special powers of her own, but he could go beyond the powers of a god!

Who does this guy think he is?! Ruby thought as she and the alien clashed yet again. He's even tougher than a Grimm! No matter, a Silver-Eyed Warrior can still beat him!

Such power! And Frieza thought the Super Saiyan was just a legend!

Even with the power increase, they were evenly matched. Goku knew he had to turn it in his favor.

"Kaioken times 10!"

The battle was becoming more and more chaotic even with the transformation. A chunk of rock on the wall came crashing down from the sudden shockwaves of the two fighters colliding.

Time to end this! With one last strike, Ruby slashed upward, knocking Goku onto his back, defeated.

"Huff…. Huff…. Huff….. ha." Ruby panted, her eyes returning to normal. Man, that was close. Wait until the others hear about this. When I get back home, of course.

Suddenly, a white pillar erupted behind her.

"WHA-!"

She shielded herself, then activated her powers again. Goku got back up…

And Ruby saw that HE had silver eyes too!

"W-what is that!?" She gasped.

"You've got a lotta power, kid." Goku smirked. "Let's see that power against the true, complete form of Ultra Instinct!"

The two charged at each other, continuing their battle. Goku freely moved to dodge Crescent Rose and whacked back the bullets. Yet at this rate, the entire arena would be destroyed by their epic battle! Dust Bullets were shot, and Kamehameha waves punctured the walls. Both knew that one or the other would be victorious! It was time to end this once and for all!

"KA…..ME…HA…ME…"

"DYYYAAAAAHHHHH!"

"HAAAAAAAA!"

The beam and streak met yet again, this time in a flash of white.

And when the dust finally cleared….

Son Goku stood victorious. As his body reverted back to normal, he told his opponent why he won.

"Sure, you look like you may be an expert at weaponry," He said. "But you rely too much on yours. On the other hand, even with you fancy eye powers, my own power increased the farther I transformed. It was pure power and strength that won this battle, so you need to not only rely on that giant sickle of yours, but you need to rely on yourself, rely on the power within you."

As Ruby got back up, Goku heard another voice behind him.

"Son Goku. Congratulations." The voice said. As the Saiyan turned, the figure who had spoken seemingly looked just like him, yet his face and appearance was different. He had a tail, yet it didn't look anything like a Saiyan's, even though it was monkey-like.

Wait, that's not Black! Who is that guy?

Is he… a Grimm? Or is he a Faunus? I've never seen a Grimm like a human before!

"I know what you're both thinking, Son Goku and Ruby Rose." The man said. "My name is Goby. I am no Saiyan. I am no Grimm. I am no Faunus." He snickered.

"I'm all three of them."

"Huh?"

"What are you talking about?"

Goby smirked. "Your two worlds have just collided with each other and many others. I am born from both of your worlds. I have both of your powers, both of your skills, and even…. both of your secrets."

"?!"

He… he knows everything about me?! Who I am and where I came from!?

"And anything either of you can do, I can do as well. Observe."

Goby began to scream as the debris around him lifted into the air. After a purple flash, Goby, now with purple hair, smirked as he drew out his twin scythes.

"I have both a fascination for weapons and a desire for combat." He said. "This is the combined power between a Mutant Grimm and a God of Destruction! Not even the teamwork of you two can become my weakness."

He then sensed another presence. He smirked.

"Not even you."

He turned around, with the two warriors shocked at what they saw.

The white clothed man confronting Goby had Ruby's eyes, yet the hair and face of Goku!

"We meet at last, Son Ruku Rose." Goby smirked. "Shall we go all-out from the start, or work our way up?"

Ruku readied his sword, Silver Sun, and transformed into a Super Saiyan.

"How about the latter?" He suggested. "But first.."

He concentrated, then teleported Ruby and Goku back to their own worlds.

"There. Now the real fight begins."

Smirking, Goby lowered his power to a mere Super Saiyan, and charged at Ruku.

As their battle began, the two warriors who had fought previously, back at their own worlds, began to wonder of this was the start of an adventure no one would forget.
