Hello again! I'm so sorry for the VERY long wait. I've been busy with school, tennis, explorers, etc. I made the chapter longer than other chapters, so I hope it makes up for the delay, so... enjoy!

"GO!"

The two racers zip right past Goku with a rainbow and yellow streak following behind them. Goku's hair sticks backwards from the force, but he shakes it off and follows the trail as the duo fly at incredible speeds. Goku smiles to himself and thinks, "Now this is more like it!"

The duo flies through the sky with intense force as they speed past the terrain below them. At first, Nimbus holds the lead with Rainbow trailing behind it. However, in a burst of speed, Dash flies right past the yellow cloud as they enter the halfway point; the forest. One after the other, they dive into the thick trees as they begin the toughest part of the race.

Both of them seem to pass the tree stumps with ease as they cut through the forest left and right. Nimbus watches as Rainbow swerves from every tree with little effort as she flies at top speed in front of it. The yellow cloud knows that it can't past her at this rate; he decides to go for a different approach.

It cuts through a nearby branch, which causes a snap to occur. Rainbow looks back, thinking that Nimbus hit a tree. However, she only found the yellow cloud to be completely unharmed, and before she faces forward again, it happens. She smashes right into a tree, but it doesn't stop there. One by one, at least ten trees are cut from their roots as the mare smashes through them as well.

Goku watches as a huge row of trees come crashing down and the birds scatter away from the wreckage. He reacts to the sight by widening his eyes and then an expression of uncertainty. He mutters, "Well that's not good."

Nimbus stops for a bit to see if the pony is ok. After the dust clears, Dash is seen getting back on to her hooves. She has a few scratches, but none of them are too serious. When it sees her, Nimbus flies off.

"Hey!" Rainbow yells before she chases him through the forest. Cutting left and right between the trees once more, Rainbow Dash trails Nimbus before they reach the clearing. They are very close to the finish line. All they have to do now is to fly upwards to the highest cloud and then shoot straight down before they reach Goku and the finish line.

The duo burst upwards as they fly higher and higher in the sky. Rainbow Dash seemed to be trailing Nimbus, and is unable to catch up. She tries to push herself even harder, but the yellow cloud always seems to be one step ahead of her as it matches the mare's speed. They were getting close now. A few more moments and then they will begin descending to the finish line below. It would seem that Nimbus has the edge and the win.

However, something clicked inside of Rainbow. "I can do it," she thinks to herself, "Push it!" They reach the highest cloud. Nimbus completely changes course and starts to head downwards at full speed. When Rainbow reaches it, she yells at the top of her lungs, "I WON'T LOSE!" She then begins her descend. She rapidly accelerates faster than a speeding bullet and all that can be seen by the normal naked eye is a rainbow blur. She feels every muscle tense up in her body, her skin burns like its on fire, and her lips are brought back by the powerful force.

It seems to work as she starts to catch up to Nimbus at a slow pace. Goku watches from not too far below as the two racers are about to fly by him and the finish. As he watches his daughter catching up to Nimbus, he smiles in excitement. "This is going to be close," he states to himself. As the two continue descending, it seems that Rainbow is actually catching up faster and faster.

Suddenly, Rainbow finds herself surrounded by a clear colored cone, which is also known as the mach cone. She just broke the sound barrier. Goku looks at this in wonder, but then the barrier got sharper. Rainbow is seen going faster and faster while the mach cone gets smaller and smaller. At this speed, she easily catches up to Nimbus, and she causes him to spin out of control as she passes him with incredible force. Nimbus comes to a complete stop as it looks back at Rainbow to see her race to the finish.

She didn't stop there. She knew by now that she passed Nimbus, but she felt a great surge of adrenaline and wanted to keep pushing herself to the breaking point. The mach cone was now almost the width of her body, and she pushed herself even harder. The next thing everyone knows, it happens.

With a sudden burst of acceleration, Rainbow accelerates to at least twice her previous speed, and she does it in style. A huge sonic boom behind Rainbow covers the sky above the forest intensely, and vibrantly. The sonic boom shows off its vast amount of beautiful colors. The outer layer of the sonic boom shines the greatest shades of red, orange, yellow, green, blue, and purple that anyone has ever seen. As the colors surround the sky, Rainbow Dash literally has a rainbow trail following right behind her.

If Nimbus could show emotions, his expression would be the same as Goku's. Goku's jaw drops as he stares at the rainbow blur zipping through the sky faster than he has ever seen before. His eyes sparkle as the glow from the rainbow colored sky reflects light from his eyes. The next thing he knows, he realizes that the she's speeding towards his direction. She is heading right for him.

Goku immediately crosses his arms to block himself from the extreme force. Rainbow zooms right past him, including the finish line, a second later, and her speed causes Goku to fly back a few feet, but he's able to keep his stance. When he looks back to see if she hit the forest, Goku finds that the rainbow streak made a sharp turn that runs toward the sky above, so he looks up. When he spots it, he finds his daughter doing something completely amazing. With the rainbow streak following behind her, she's forming an arc high in the sky. She's literally producing a rainbow.

Rainbow feels amazing. This has to be the fastest she has ever gotten in her entire life. She decides to turn her head to see any damage that might have accidently been caused, but what she really finds struck her. She finds a rainbow trailing behind her, and the vast amount of colors that surround the entire sky. Her eyes widen from this in shock. She then focuses on looking in front of herself again, and has the same expression on her face as she tries to take it all in. When she does, she makes a wide grin and thinks to herself, "Now this is awesome!"

She opens her wings and levels them parallel to the ground when she gets close to the surface in order to land in the clearing of the forest. She begins to slow down rapidly and touches the ground softly moments later. When the mare looks behind her in order to find her dad and Nimbus, she spots the rainbow that she caused. The colors shine in the sky with the power similar to the full moon on a perfect night. The rainbow can be seen sparkling intensely and the colors spread throughout the entire atmosphere above her. Rainbow gazes at it with a look of aw before she spots something else.

Two dots are seen in the distance and they increase in size as if they're heading right for her. The pony already knew who they were. A few moments later, the dots grow large enough to be identified as Goku and Nimbus as they head right for Rainbow Dash with excitement on Goku's face.

"Way to go Rainbow!" Goku yells before he lands on the ground and runs over to her. When he reaches her, he immediately comments, "That was the fastest I've ever seen you! You really outdid yourself this time!"

"Sorry dad," Rainbow replies with a smirk, "I couldn't help myself."

Goku wraps his arm around her and scruffs her hair as he says, "That's my girl."

"Rainbow Dash!"

The pair turns to find Chichi running over to them with Gohan behind her. Rainbow finds a concern look on her face, and she immediately knows why. When she reaches them, Chichi immediately hugs Rainbow and says, "Thank goodness you're alright! I was so worried about you."

"Didn't you see the awesome rainbow I made mom?"

Chichi stopped hugging Rainbow and then the worried mother started to check her daughter's entire body for any damage. So far, she hasn't seen anything out of the ordinary. "I did, and it was very beautiful, but I heard you slam into the trees in the forest before, so I was so worried about you-"

All of a sudden, Rainbow can hear mother gasp. Rainbow looks over to her mom to find her… staring at the side of her rump. The pony is very confused by this, so she asks, "What's up mom?" Chichi doesn't respond for a short period of time, but then she slaps the mare in the back of the head. "Hey, what was that for!?" she yelps. Now Goku and Nimbus are confused.

Suddenly, Chichi yells at her daughter, "What did I tell you about getting a tattoo!?"

Rainbow immediately gives her mom a confused look, and Goku just looks dumbfounded. "A what?" Rainbow asks. She looks back to see Gohan looking at the same spot her mother did, and the he stares at it in wonder as if it's a new toy. Rainbow Dash glances over to what her brother is looking at. At this point, Goku also catches a glimpse of something he catches on the other side of her flank, so he adjusts his view to see what it is.

Both Goku and his pony daughter grow wide-eyed in shock at first. There's definitely a tattoo there, but neither of them knows where it came from. The tattoo shows a grey cloud, and there are three lightning bolts below the cloud. Each lightning bolt has a different color; red, yellow, and blue. These lightning bolts also seem to be stuck together to form one huge lightning bolt.

Goku quickly move to the mare's other side, and is again shocked by what he sees. Rainbow seems to have the same exact mark on both sides of her rump. Rainbow Dash begins to smile. "I don't know where it came from," she says, "but it sure looks awesome."

"Awesome or not young lady," Chichi speaks harshly, "You're going to get that thing removed by tomorrow."

"But mom, it looks so cool! Besides, one can't hurt, right?"

While Chichi and Rainbow argue back and forth on what would be the fate of the tattoo, Goku starts to question the very thing that most of the family hade in mind. "Where in the world did that mark come from? I know I haven't seen it at all today. Heck, I don't even remember seeing it when she was next to me before-." As if a light bulb went off in his head, Goku is hit by the realization. "The race." He turns to the sky to see the rainbow that shined the sky before, and it now fades away as if it evaporated into thin air. Goku then looks back at the mark that's on Rainbow while she and Chichi are still arguing over it.

"Come on mom! I have no idea how I got it, honest." Rainbow says.

"How am I supposed to think that you got that tattoo out of the blue? I swear, one more bluff like that and that's not the only thing you'll be loosing!" Chichi yells in return.

"I don't think that's a normal mark Chichi." Goku interrupts.

Chichi and Rainbow quickly turns to him. "What the hell is that suppose to mean!?" the mother asks.

"I didn't know how she got it either, and I was right next to her before the race." Goku notices that Chichi keeps her tense, pissed off expression on her face before he continues, "Just think about it. How can she get one without even going to a tattoo artist? Wouldn't she be caught by those government guys that you talked about if this was true?" Chichi's expression softens a little bit as the reality struck her. "And besides, didn't you notice that she has the same mark on the other side of her flank as well?" Chichi and Rainbow are struck by this and they turn to the other side of the mare's flank. He's right. The same mark is on that side as well. While they stare intently at it, Goku continues, "I think that rainbow that she made had to do with it." Rainbow, Gohan, and her mother look back at Goku after he says this. "This mark might be a symbol for something, like her special talent."

"You really think so?" Chichi asks.

"I'm sure of it. The mark suits her, too."

Chichi looks back at the mark once again, and she would have to agree. "I guess you're right."

Rainbow smiles at this before asking, "Does this mean I get to keep it?"

The pony's mother looks at her for a moment. She then sighs in defeat and answers, "Yes, you can keep it."

In response, Rainbow cheers while Gohan giggles joyfully. Goku grins before I thought popped into his head. "Say, how about we give that move a name. Don't you agree Rainbow?" Goku asks the mare.

Rainbow looks back at him and smirks before replying, "Are you talking about that Sonic Rainboom I made?"

Everybody looks at her before Goku responds, "A Sonic Rainboom?"

"Ya, I came up with the name myself. You like?"

"That sounds like a fine name sweetie," her mother answers.

"I'd have to agree with you there," Goku comments, "I wouldn't have it any other way."

"Then it's settled," Rainbow states, "The new technique will be called the Sonic Rainboom!"

Gohan giggles at this while Chichi smiles. Goku smiles as well, and then looks at the mark again with a pensive expression before he looks behind him and towards the sky where that rainbow was before. "The Sonic Rainboom," he thinks to himself. He grins at this before thinking, "That's a perfect name."

This has been an interesting day for Goku. Not only does his daughter create a technique that he has never heard of before, but she also gains a strange mark that no one knows where it came from. For now, Goku thinks that he will eventually find out these mysteries in the far future. It's late October and the Son family is ready for the upcoming holidays, so Goku also thinks that it's only going to get better for the family.

If only he knew what's going to happen the very next day.
