Chapter 1: Ace! The Saiyan Warrior!

Prologue

The Future Warrior or simply called Ace was flying around in space. He guided a CC (Capsule Corporation) spaceship. It was small, made for one person. It was yellow, blue and white. It reassembled Jaco's spaceship.

The logo of CC was on the side. Ace sighed, wondering why he was doing this particular mission. It started back in the Time Nest...

~Flashback~

"Oh, my, Ace, Trunks come here!" A female voice called out. It was Supreme Kai of Time or known as Chronoa. She kept an eye on over the flow of time.

"Oh wait is it now?" An older man's voice said. It was Old Kai; he advised the current Supreme Kai over Universe 7.

"Kehhhhhh!" A bird call ranged out. It was Tokitoki; he is a divine bird with the ability to create time within Universe 7. Furthermore, Chornoa is the caretaker of Tokitoki as well.

Chornoa, stood alone in the middle of the Time Vault. It was a special place, within the Time Nest where she and Tokitoki live. The Time Vault keeps the entire history of everything!

There stood a table alone in the Time Vault, books scattered all over it. Chornoa frantically searched through all the books for something! She has found it at last!

"There! After hours of looking! I finally found you! Ace! Trunks!" Chornoa shouted. Old Kai entered the scene, hands behind his back.

"What's happening? You found something interesting?" Old Kai said. He wondered about his fellow Supreme Kai.

"Yes! Old man, it took me a bit, but," a couple of footsteps echoed throughout the place. Chornoa and Old Kai looked at the entrance.

A purple-haired guy along with a jet-black haired person came. It was no other than Trunks and Ace! You see, they are heroes of history!

Trunks is the son of Vegeta the IV and Bluma Brief. A hybrid between an Earthling and a Saiyan. He helped Goku and the others with their fight with the androids and Cell before. Trunks didn't know he broke the rules of time. Now he is forced to help the Time Patrol! He became one of the strongest and best warriors they can offer.

Trunks' attire is a World War-esque black trench coat with a fur-lined collar and an olive green sweater underneath, olive green pants with lighter-coloured bandages around his shins and brown coloured laced boots. Don't forget his sword, that he used to kill Frieza!

Ace is a Saiyan from a "faraway land." He doesn't have parents you know why? When Trunks asked Shenron for a mighty warrior to defend history. Shenron instead created Ace from scratch. It was weird for him, and for others to find out. However Ace didn't mind that, he wanted to save people and look for a good fight. Ace fought and killed Demon God Demigra, along with the help of Trunks and Goku! Ace is now the most active fighter in the Time Patrol; he has many titles. Like, "Toki Toki City Hero," or, "Mysterious Warrior," etc.

Ace's is a young male, his hair and facial features are similar to Gohan and is fair-skinned. His attire is an indigo Capsule Corporation jacket, a white cape, gray pants, and golden boots. A green Scouter rests on his left ear.

"What's going on? Is there a disruption in history?" Trunks asked his superior. Ace nodded along; he doesn't talk that much.

"No Trunks! I finally found the planet that I've been looking for a long time!" Chornoa explained, she held up a brown book. It was rotting away, with the words, "Remnant's History," on it.

"Remnant? Never heard of it," Trunks replied. He and Ace came closer for a better look.

"Remnant? I didn't hear about it either," Old Kai added his two cents. The word did make him think for a bit. Old Kai swore he heard it before.

"Yes, Remnant! It's a planet near the edge of Universe 7. I am surprised that it's still there from Frieza's army plaguing the universe or Majin Buu's destruction millions of years ago. I forgot about it too, until an apple fell on my head," she explained. She opened the book and started to flip and scan each page.

"... Oh, I remember now!" Old Kai shouted. Trunks and Ace listened, while Tokitoki flew in the air. "Kehhhhhhh!"

"It's a very ancient planet! It resides near the edge of the universe. Let me think... OH yeah! Believe it or not, Humans live there. Also, an animal-like race live's there too. The race's name is "Faunus," I think," Old Kai stretched his head.

"Humans!? Amazing, I can't believe there's Human's out there, besides Earth. Faunus? They sound neat; we do have animal-like warriors here. What do you think Ace," Trunks asked Ace, who nodded.

"Eheheh, you don't talk that much, I forgot. Well, anyways you found anything appealing about this planet, Supreme Kai of Time?" Trunks wondered more about this planet.

Chornoa closed the book, giving out a smile. "Yes, I did. I didn't find lots of things. However, I found some interesting stuff. It turns out a seal kept them hidden from us," Trunks and Ace gave a surprised look.

"A seal? How," Old Kai asked.

"Two beings, The Gods of Light and Darkness, made it. It said, they left the planet a long time ago. It doesn't give a reason why. They made a magic-like seal around it, hiding it from the outside world. Until now, the old man and I rethought of it again," The Supreme Kai of Time explained.

"Old man!? We're only thousands of years apart!" Old Kai yelled.

"Anyways, now the seal should be broken. The book only says so much. It does tell the seal would break after a couple of millions of years later. I don't know what happened to the Gods of their world, they disappeared."

Ace jumped into the air, smiling away. Trunks knew what his action means. "You're happy right? You are wondering how powerful they are?" Ace nodded, hoping they would appear so they can fight him.

"Ace didn't have a good fight since Demigra. He pushed you beyond Super Saiyan, to Supers Saiyan 2, right?" Trunks asked Ace, who nodded again.

"Ah, you Saiyan's and your fighting. I am surprised Ace didn't go Super Saiyan 3 yet!" Old Kai said.

"Well, you wouldn't believe this. Yesterday Goku came and trained with Ace. Who can now finally go to Super Saiyan 3!" Trunks explained for his friend. He is amazed by his friend's power!

"Woah? Good job! I am sure you'll become stronger Ace!" The Supreme Kai of Time cheered for Ace, who blushed from the praise.

"Good job young one! Another step in your growth! Now enough about that. Back on the topic on hand! Found anything else out?" Old Kai said.

"Yes, turns out they use "Dust." It's a source of energy over there. The book doesn't say much; I am guessing they use it for machines and stuff. They also have creatures called "Grimm." That's about it. Nothing else most of the pages of empty," she let out a gasp.

"I have an idea. I want Ace to go to the planet and record data for the book. We can't have a book without no knowledge here in the Time Vault!" The Supreme Kai of Time said.

"Sounds good," Trunks nodded, along with Ace and Old Kai.

"Good, Ace prepare to leave in a day or so. Guys, I believe we got something special here!"

"Of course, I wonder what is "Dust," and "Grimm" is," Old Kai said.

"Me too," Trunks also said, with Ace nodding away.

Back to Ace In The Future

Ace flew faster throughout space. "Hey is this thing on?" The Supreme Kai of Time said, "Yep," Old Kai also said. Ace was getting closer, he can feel it.

He wondered about Grimm, creatures they said. Are they strong? He wants to believe that. Ace feels his Saiyan blood boil like a raging fire.

"There! I can see it!" Trunks who was there from the start yelled. Ace peaked up; he saw the planet. It was dark; the moon looked broken.

It looked like Earth, but a lot darker. "Huh, wasn't expecting that," Old Kai said over Ace's Scouter. "Yeah, it doesn't look great," The Supreme Kai of Time added. Ace shrugged as his spaceship descended onto the planet.

Ace's spaceship started to shake, "Something is wrong-" the transmission between Ace and his allies broke off. Ace clicked his Scouter, over and over.

"Huh, guys," Ace finally spoke. His voice also sounds like Gohan. "This isn't going to end well!" Ace's spaceship erupted in a ball of fire.

His spaceship entered the atmosphere. Ace was crashing landing, more than landing!

"I got no other choice!" Ace got up from his seat. Ace suddenly punched the glass dome around him; he flew out of it as his broken spaceship flew into the clouds.

"Woah, I better get down fast," Ace flew downwards.

Ace entered the clouds; he felt the air. It was rather nice and warm. That doesn't change the fact, that his spaceship is crashing landing!

Ace flew faster towards the ground to save it... *BOOM* or not.

Ace stopped himself, "Well there goes my ship," it crashed landed into a forest area. A fire started to spread around it; it made a crater. "That isn't good," Ace descended on the ground.

He sighed, as he watched it burn. "Great, now what?... I should start looking around now," Ace pressed his Scouter, it scanned around him.

..."There!" Ace pointed towards a random direction. "I see power levels over there! Four I read, one is 13, one is 24, one is 28, and the last one is 39."

"Hm, they are weak, a Saiyan baby is stronger, eh. Doesn't matter I should go over there now!" Ace flew upwards and used his speed to move fast.

Jaune Arc's POV

I can't believe this! Why is there so many Grimm here! Our mission only says there should be only twenty Beowolfs! It's doubled, luckily my team is doing good, at least. Ren and Nora are destroying them one after another. Pyrrha our real star is taking them down easy. Me, I am useless as usual.

"Jaune watch out!" Pyrrha shouted at me? I turned to look; a Beowolf came to swipe me. I brought up my shield to block it. "Hold on I am coming!"

Pyrrha yelled she got surrounded quickly. "NORA SMASH!" I hear Nora using her hammer to break Beowolf's left and right.

"Nora! Don't be so reckless! Ren's echoed, he used his weapons to slice and dice them easy. They keep on coming and coming!

"There's more coming guys!" I shouted I turned to look as more came. Ten more, I used my trusty sword and cut the head of the Beowolf.

"Pyrrha watch out!" She quickly killed three; she didn't notice one creeping on her. "NO!" I yelled out, is she going to die? I am useless; I should've never come here...

No one's POV

Jaune Arc was going to watch his partner die in front of him. Pyrrha turned and met with a claw. Suddenly a small blue Ki blast came. It instantly set the Beowolf to dust.

Pyrrha and Jaune had surprised looks, "Huh, Dust Bullets?" Pyrrha said out loud. They looked up to see him!

Ace had his arms crossed, with his white cape flapping in the wind. His right eye only showed, with his left one covered.

"Hmph, they just have a power level of 8, disappointing." Ace quickly landed on the ground.

"I see nine-teen of them, easy," Ace disappeared.

To them, he disappeared, but he is going fast. Ace quickly went through each one, punching and kicking them to oblivion! Ren and Nora had their backs together, as the Beowolf's eight in totelly died instantly in front of them.

"W-w-what? I can't see him!" Nora shouted, who was puzzled.

Only a couple of seconds went by, as all of the Beowolfs died. Ace reappeared behind of Jaune.

"W-w-who are you?" Jaune question the mysterious man.

"Me, I have many names. But for you, call me Ace... The saviour of history and time." Ace stated.


Alright I changed a few things. First this takes place before the 2nd game, Ace now has jet-black hair. He's a Saiyan he has to. I left the name still. I won't change this into Ace going around one-shoting people. That would be boring as shit. I wanna keep this intresting, like I said beforehand. Anyways, thanks for reading dis shit.
