"Hey come on give it back!" A peagsus colt named Hoops said who was currently trying to get his favorite basketball from the ego-maniac Rainbow Dash and one of her friends Spitfire. Dash wasn't exactly the kindest pegasus like it was stated she had a massive ego, a bad attitude, a record of pick pocketing and stealing from many pegsi.
This behavior ended up rubbing off onto her friends Spitfire, Soarin and Lightning Dust. They even went as far as to call themselves the Shadowbolts and even gave Rainbow the leader the nickname Slippery Eel the first part relating to her illegal hobby and the second part to her name and some irony since the group lived in Cloudsdale the highest point in Equestria.
Rainbow and Spitfire continue to throw it back and forth when Soarin joined and when they tossed he pulled out a needle. "NO! Please don't pop my ball!" The basketball colt says in a begging position "Oh yeah what are you gonna do about it?" right as he is about to make the needle touch the ball, a portable ball air pump pokes him directly in the making him drop the basketball which is caught by Rainbow.
"OUT OF MY WAY!" Hoops shoves Spitfire aside which quite frankly serves her right
"GIVE IT BACK!"
"Oh yeah you want it try to catch me! See ya loser!" Rainbow dashes away Hoops following behind now enraged.
Meanwhile back on the ground level in Canterlot was Twilight Sparkle who was trying to pass an entrance exam by hatching a dragon egg, key word trying. Speaking of trying the whole reason why she was doing this was because she was trying to enroll in Princess Celestia's School For Gifted Unicorns.
"We don't have all day." One of the judges reminded her, the filly attempted to use her magic on the purple dragon egg but only managed to release a signal spark before giving up.
Back in Cloudsdale
"See ya loser!" the rainbow maned filly said rudely knocking Hoops aside. Knowing that he could catch up to her again, gained a really sudden spike in speed and when she hit a cloud ring she seemed to release a massive sonic boom like rainbow wave.
"HA! You didn't catch me!" the filly bragged and taunted to the colt who was recovering from her sabotage. She gently punches him which also gives him a static shock which she swore was rainbow rather than yellow or blue.
"What in Celestia's name was that?" she asked herself and tried to do it to Hoops again but the electricity seemed to have gone away.
Back in Canterlot Twilight Sparkle by this point had given up on trying to hatch the dragon egg "Sorry I wasted your time." she said admitting defeat which was followed by the sonic rainboom going over the area. Twilight's eyes glowed and her horn shot a strange rainbow bolt of electricity which shattered the egg to pieces releasing a baby dragon which was still surging with rainbow electricity.
Twilight was enveloped in a blob of the same rainbow magic. Not wanting to accidentally use it on anyone tires to control it. "Must..keep...it...stable!" the unicorn filly ends up absorbing the magic into her body most of it getting in her brain and as a result she blacks out.
Once Twilight was placed onto a stretcher, into an ambulance and headed towards a hospital the stallion who brought the dragon in now wearing electricity insulated gloves picked him up and placed him in a box "You're clearly no good anymore." he says planning to throw him into the alley behind the building only to drop his glasses into the box.
"AH WHERE THEY GO!" he stumbles around trying to find his glasses only to trip and drop the baby dragon's box into Canterlot's stream which goes down a waterfall and into a river. The box eventually washes up on Manehattan beach where the dragon is somehow not found by anypony and ends up living on the streets growing up.
A Few Years Later
"AH HA FOUND THE JACKPOT!" The teen dragon who had named himself Spike says reaching into a dumpster and into bag full of clean unsold, leftover donuts. He grabs a glazed one but before he can take a bite it slips out of his grasp and ended up in the middle of the road.
Looking forward and behind for ponies rather than left and right for cars. He went for the treat only to see a black van speed towards him. He closes his eyes and braces for impact but that never came, not because he wasn't hit in fact he was right in front of one of the wheels but because he had somehow flipped the van over which had knocked out pony bank robbers and all their stolen money.
Not wanting to be seen and with no hiding place in range he stupidly jumps to backwards. This move turns out to be not so stupid as he suddenly find himself floating in the air. He yelps and allows himself to fall back to earth faceplanting into the pavement which damages the ground with a crater rather than the dragon with serious injuries.
"Was I flying?" he asks himself before noticing that he had grown a pair of wings. Reaching into the box he originally arrived in he pulls out a Superpony comic book "Superpony had invulnerability the inablity to be hurt by anything from heat to explosives."
"Could I also have-" he picks up a dumpster full of trash which would usually weigh a bunch but to Spike it was as light as a single donut. He places it down he tries to breathe fire but nothing comes out, annoyed he stares at a metal trash can only to see it start melting.
"May not have fire breathe but I have a fire stare." Spike thought as he referenced the comic again "A costume I need a super suit."
"This design will just simply never do!" Spike heard a voice say which turned out to be a white unicorn mare who threw out some kind of shirt. Once the mare had left he checked the failed design which to him looked pretty nice it was a red long sleeve shirt with a U on it, it also came with a belt with the same letter on and a black face mask. Spike checked the belt out and found it was trademarked by a buckball team named the Underdogs.
"Now for my superhero name something that starts with a U....Underdog...Underduck...Underdrake that's it!" Although drake to some ponies referred to a male duck, to others it meant a flightless dragon which to Spike sounded ironic since he had wings. He tires the suit on, adjusted the belt to fit him but found the red shirt a bit oversize "Eh i'll grow into it."
Princess Celestia checked up on her somewhat faithful student in her personal quarters only to find papers scattered all over the floor. A bit concerned the powerful unicorn approaches the younger one who had her back turned to a random corner.
"Um how are the studies going Twi-" she cuts her own sentence off when Twilight turns around revealing an injured pupil "What happened?!"
"You want to know what happened?! A tried asking one of my guards for some candy but he refused he told me I wasn't a high enough rank but I'm a princess the highest rank a pony can have he even went as far as he poke me in the eye with his spear.
"I'm sure he didn't mean to, maybe you made him." Celestia suggested which Twilight cringed at "He poked me like this!" the filly stupidly pokes her injured eye with a sharpened pencil, making scream and stumbled around eventually slipping on some paper.
"My faithful student you can't be indulging yourself in crazy fantasy, becoming a princess takes a lot of hard work and the role itself is not a walk in the park.
"Fine you won't support my role of princess I show you! i'll show all of Equestria!" Twilight starts laughing like a maniac and jumps out a window somehow unharmed by the glass. Where she found her brother Shining Armor mopping the floor "Hey Shining come on!"
"But Twily I'm training to become a Royal Guard!"
"I know a better way to become one!"
"Yeah no, sorry little sis i'm taking the sim-" he gets cut off by his deranged sister firing a spell at him which turn his eyes pupils from black to blue.
"As Princess I command you to follow my orders! Follow me!" Twilight says which seems to work as the stallion starts following the latter command. Twilight knew that the only way to get her unruly subjects to obey her was to take over Equestria.
A Few More Years Later
A large figure loomed in the streets of Manehattan and once it had come out of the shadows revealed to be a crab tank, robot with 2 metal crab like claws and a furnace that acted as some sort of mouth, which was operated by a messy maned, eye patch wearing unicorn "Attention citizens of Manehattan surrender yourselves and your city to me Princess Twilight Sparkle or see it and yourself utterly destroyed."
Crowds of citizens started laughing at the slightly older unicorn and her piece of machinery, which even got the attention of the city's mayor Mayor Mare who joins in on the laughter.
"Run along little unicorn you can play with your toy somewhere else." Mayor mocked struggling to hold her laughter back. "You think i'm playing?" Twilight asks pulling 2 levers which makes the 2 claws grab the mayor and lift her up "Surrender your city to me or else!" the deranged pony demands then lowering the mayor to the open furnace threatening to throw her in.
"You won't get away with this!" A white unicorn mare says
"I'll take that as refusing to surrender!"
"No need to shake here's Underdrake!" It becomes Twilight's turn to laugh at the super dragon more specifically his suit. "You call yourself a hero your suit doesn't even fully fit you."
"You release her at once or else!" he says rolling one of his sleeves up and balling a claw into a fist "Let see you handle this!" she deploys an entire pad full of heat seeking missiles and since dragons were pure heat they all homed in one him. Underdrake manages to grab the first one, bringing it to a stop right before it can push him into a building and destroys with his super strength crushing it into a ball.
He gets overwhelmed by the rest of the missiles which directly strike him. Despite this once the smoke clears up both him and his suit are shown to be okay.
"WHAT IMPOSSIBLE!"
"invulnerability ever heard of it?" The unicorn switches to her last resort and goes to throw Mayor Mare into the mouth furnace only for Underdrake to crash right through the furnace destroying the robot in the process. The smoke clears up to reveal both creatures unharmed simply covered in soot.
Twilight on the other hand ended up under a pile of rubble, she's picked up the heroic dragon. "You saved the city er....Underdrake."
"That's right i'm just here to keep Manehattan safe!"
"You know Underdrake a hero like you deserves a kiss!" the white unicorn mare offers, the dragon blushes and backs up. "I'm a humble hero, a true one, not looking for any rewards, please and thank you fellow citizens." he says then takes off at a supersonic speed, where he drops Twilight off in jail.
"Look up in the sky it’s a bird!" Special Delivery started
"No it’s a plane!" Parcel Post countered
"It’s a snake!" Derpy randomly added
"A snake?" the 2 mail stallions asked
"No bird nor plane or snake just friendly old me U-" the dragon crashes ends up crashing into a clock tower. "Underdrake!"
