"Applejack, wait!" shouted Applebloom, waving her hooves frantically in the air, looking wide-eyed at the stubborn mare headed full-throttle towards Goku, "Don't hurt him, Goku's real nice!"
"Ah'll teach y'all ta hurt mah family, ya giant shaved ape!" roared Applejack, her eyes set on the creature in front of her. Applebloom shouted again as her sister spun around, planted her front hooves before pulling in her hind legs as far as possible and thrusting them back with enough force to uproot an old oak.
A thud embellished with terrible cracks echoed around the forest.
"Hey, are you alright?" Applejack collapsed as Goku crouched for a better view of his aggressor, "You don't look so good, could you use a little help?"
"W-what in the hay are you m-made of?" whimpered Applejack, struggling up to four hooves only to collapse in a pile at Gokus' feet, "F-felt like ah was b-buckin' a steel wall."
"Sis!" Applebloom shouted, squirming her way out of Gokus' grip and running over to Applejack, tears streaming from her eyes, "Yer so stubborn! Ah told ya not ta try an' hurt Goku."
"W-what are you doin' with a m-monster like that, anyway?" Applejack looked back at Goku, "An why am I the one unable t-to get up? Y'all shoulda went flyin'."
"Goku ain't no monster, Sis! He's a say-an," Applebloom slowly mouthed the syllables to 'saiyan', "an' he saved us from a pack a timberwolves!"
"You should've seen him go! He was like BAM and POW and BOOM," Scootaloo struck at an imaginary enemy along with the Goku in her memories, "and then he was all," she deepened her voice in imitation, "'You lose. Leave now.', and they all ran away! It was like something out of Daring Do, but with even more action!" she let out a small squeal of excitement before glancing around, blushing slightly.
Goku laughed nervously, "It really isn't that big a deal, I was just doing what anyone would do." He gave a bashful smile, "I was just helping those who needed it. Really, no big deal!"
Applejack looked at Goku incredulously before widening her eyes and looking around the group, an irritated look covering her face, "Now where did that Rainbow Dash fly off to now? Probably took one look at this here 'say-an'," her pronunciation wasn't any better than her sisters', "an' ran away ta nap." she chuckled lightly at her joke.
"Hey! You take that back! I'll deal with this so-called 'say-an' myself, just lemme -" Rainbow grunted with each effort to remove herself from her bindings, binding her tighter the more she struggled, "- get out of these stupid -" another series of grunts followed by an exasperated sigh, "- vines. Um, Applejack? Little help?"
"Here, I got it." said Goku, before pointing his finger at one of the offending vines.
"Um, what're you doing? How is that gonna hELP! , " Goku shot a bright yellow ki blast straight through one vine after another, riddling the tree behind Rainbow with small circular holes that passed right through its' aged trunk. Rainbow landed on her back and easily shook off the now detached vines, and thanked Goku. She made to fly towards Scootaloo, before her face joined the others in shocked amazement, "Wait, did you just shoot lasers?" she motioned towards Gokus' hands, "Out of those?"
"Lasers? No, those were just low-power ki blasts, nothing impressive," Goku replied, before turning his head towards the sputtering purple unicorn standing there. Her right eye twitched, pupil practically non-existant, her pink-striped purple mane noticeably disheveled. Goku could have sworn he saw steam rising from her ears.

"Urgh! Those two always running ahead!" an exasperated Twilight grumbled.
"You heard Rainbow Dash, Twilight! Let's go save the crusaders from the super scary thing!"
The four remaining elements (and Spike) sprinted down the overgrown path. Twilight led the group, Pinkie Pie bouncing along, a shivering Fluttershy draped over her back, not slowing her pace. Rarity barely kept up with the others, dodging from side to side, away from anything deemed remotely dirty by her keen eyes.
"Yes, but it's a bad idea to just charge in without a plan. We should observe, take notes and calculate strategies. Celestia knows what those fillies have gotten themselves into this time!"
"Darling, now is neither the time nor the place to spend time planning. My sister could be in danger for goodness sake!" Rarity ran straight through a particularly muddy spot, "Eugh! No, be strong, Rarity, for Sweetie Belle!"
They ran in relative silence (that is, Pinkie Pie talked, the rest tuned her out) before Twilight skidded to a halt.
"Here, I got it." said a strange creature, pointing it's... claw? at an entangled Rainbow Dash, before blasting the vines with what Twilight could only call high-powered magical beams. But it had no horn and practically no magical signal, "Wh.. Buh... How.. I-I... What?" Twilight bumbled, speechless at the display of powerful magic.
"Sweetie Belle!" Rarity cried, eyes locking onto the unmoving form of her sister, grasped in the creatures' forelimbs, "Get away from her, you brute!" she lowered her head in challenge, her horn glowing blue as she levitated around twenty gems out of her saddlebags, pointing them at Goku, "Or you'll regret it!"
"Rares, wait," Applejack stated, the authoritarian calm in her voice causing Raritys' ears to twitch in acknowledgement, "Apparently this here 'say-an' -" Goku interjected with the correct pronunciation, "- saiyan, right. Well, this here saiyan saved mah sister an' her crusader friends from a pack a timberwolves."
"A pack?! By itself? And you believed it? We both know that's impossible -"
"- Ah know, they jus' put themselves back together whenever ya hit 'em," Applejack shook her head a little, "But ah also know lies whenever ah hear 'em. An' my sister ain't lyin' about this."
Rarity stood there for a moment, shards of moonlight bursting through the heavy canopy and reflecting off her mane. Either it had somehow survived the dash through the forest, coming out in perfect condition, or she had found the time to style it again after stopping. Goku couldn't tell which.
Something pink twitched behind the alabaster unicorns' equally well-kept tail. Originally brushing it off as some fabric, Goku diverted his attention before returning it as he sensed a separate power to Raritys'. A small one, mind you, but definitely a real one. He leaned to one side, peering behind Rarity. The pink thing ducked further behind her cover, avoiding Gokus' gaze, before Gokus' eyes shot left. He flipped back in a display of great speed, barely avoiding the bright pink blur that almost collided with him.
"Woah!" Goku shouted, performing a perfect landing, Scootaloo clinging to his head and shaking slightly, and Sweetie Belle somehow still asleep, "What was that?"
The pink blur was now sprawled on the ground, revealing itself to be an aggressively pink (Goku could vaguely remember Vegeta once wore a shirt of similar colouring) earth pony mare, the mud that now covered her fur and mane doing nothing to dull the colour, "Hey, no fair! Nopony avoids a Pinkie Pie hug!" Pinkie pouted momentarily, before hopping over to Goku, "You must be, like super-duper ultra fast to dodge it!" she leaned in to Goku - the gesture losing a lot of its' intended effect due to her being waist height at best - and whispered, "Maybe even faster than Dashie. Don't tell her I said that, though." she gave an exaggerated wink, "Anyway, I'm Pinkie Pie, resident party pony of Ponyville! These are my friends: Applejack -" she gestured a hoof towards the stetson-wearing orange earth pony, "- she grows the bestest apples in Ponyville, Rarity -" a pointed hoof directed Gokus' eyes towards the white unicorn with the purple mane, "- she makes brilliantly fantastic dresses that are super pretty, Rainbow Dash -" the cyan blue pegasus with the rainbow mane and tail, "- she's, like, super-amazing at flying! Did you know that she's the only pegasus in history to pull off a sonic rainboom? I know, crazy, right! Anyway, fluttershy -" Pinkie pulled the pastel-yellow pegasus with the pink mane from behind Rarity, "- She's such good friends with animals! I've never seen her not be friends with an animal. I mean, can you imagine what it would be like if she wasn't friends with an animal? This one time, I met a pony who didn't want to be friends with me. Me! And I'm friends with everypony! It was terrible! And, last but definitely not least, Twilight Sparkle! -" the purple unicorn with a darker purple mane with a pink stripe, "- She's the most super-powerful unicorn ever! Of course she is! She's the element of magic! There was this one showpony who said she was more powerfuller, but Twilight sure showed her! Anyway, now you know a little about us, you can tell us all about you!" she giggled, a hoof covering her mouth slightly, "Oh wait. I forgot to ask your name." she concluded the introduction, panting slightly from speaking for a good ten seconds straight without stopping.
"Well, I'm Son Goku, but my friends just call me Goku and, erm, I'm a saiyan and..." he struggled to find the words, "Hey! How about you ask me a question, I answer it, then I can ask you a question!" Goku beamed at his idea.
"Don't tell me ya caught all a that?" Applejack asked, her disbelief evident, "Nopony's ever kept up with Pinkie Pies' introductions."
"Sure I did!" he pointed to each of the six mares present, "Twilight Sparkle, Fluttershy, Rarity, Pinkie Pie, Applejack, Rainbow Dash. See!" he gave a grin, before noticing the purple lizard on Twilights' back, "Hey, what are you?"
"Um, m-me?" asked Spike, pointing a shaking claw at himself, "I-I'm a dragon. M-my name is S-Spike." he extended a claw. At full height, Goku estimated this dragon would probably come up to his knees at best.
"A dragon? Like Shenron or Porunga or just a regular dragon?"
"Who're they? And what do you mean 'just' a regular dragon?"
"Regular it is! Although you are a little small by dragon standards. Maybe that's different here, too?"
"Small?!" Spike gave a snort of indignation, "I'm still a baby! Just you wait 'till I grow up, I'll be bigger than a house!" he puffed his chest out in pride, "Then we'll see who's 'a little small'!"
"Geez, touchy subject!" Goku whispered to Applejack, eliciting a giggle from her, "Now, who's first?" Everyones' hooves shot up in the air, even the downed Applejack, who Goku pointed towards, "Applejack."
"It's gettin' a might late, shouldn't we be headed back? This forest ain't safe at day, let alone night!" A chill seemed to pass through the whole group apart from Goku, who looked on, confused.
"Tell you what, point me in the right direction and describe someone in detail, and I'll get us there in the blink of an eye!" Applejack looked on, confused, before telling Goku about her brother, Big Macintosh. Goku smiled, nodded and placed an extended index and middle finger on his forehead, "OK, everyone, make a chain. Be sure to touch someone who is touching me, or me directly." they all obeyed the saiyans' orders with varying amounts of confusion and distrust.
Big Macintosh paced back and forth in front of the Apple family barn. His eyebrows furrowed in concentration as he stared intently at the distant Everfree and Ponyville, interchangeably. He knew the time it'd take his sisters to reach Zecoras', and that had long since passed. For what was probably the hundredth time today, he walked towards the forest, only to pause for a second before getting back to his post. He was not going to miss his sisters' safe return.
"Group teleportation... Over two miles distance... Accurate down to the inch... NO HORN!" Twilight blinked, her pupils widening as smoke billowed out of her ears in full plumes. Big mac jumped a foot in the air before turning around. A grin formed on his muzzle when he saw Applebloom unharmed, but quickly left at the sight of Applejack laying in the dirt. He rushed to her side.
"Earth to Twi... Hello, can you hear me?" Goku waved a hand in front of her face, "Great, I think I broke her."
"You have reached the answering machine of Twilight Sparkle. I'm afraid she can't take your call right now, but please leave a message after the freak out, and she'll get right on it. Have a nice day." Twilight stated in a perfectly level voice before screaming, followed by a few (read: hundreds) of choice words in quick succession. The others still occupied themselves with twisting their heads around and blinking madly. Only Pinkie Pie seemed unaffected.
This is actually Chapters 3 and 4 of the story. Chapter 3 was too short, so I decided to fuse them together.
