Her name is 'Sweetie Belle'...

... and she was just woken up by Rarity's scream, frightened out of bed by Spike's roar, and ran down stairs looking for her sister when she found Rarity's bed empty: fortunately not coming into the room until AFTER spike and Rarity's genitalia had vanished, but now being under the misapprehension that her beloved Sister is being attacked by a teenage dragon! Even more unfortunately she is almost utterly fearless, under the delusion common to most 8-17 year old foals that she is invincible, and has been taking lessons in Judo... All of these factors combine result in a VERY poor decision on her part...

"Let go of my SISTER!" She cries launching a flying kick at Spike's head which Spike jerks out of the way letting the airborne foal fly past, slamming instead into one of Rarity's modelling mirrors and breaking it into dozens of razor sharp shards. Undaunted the she rounds on Spike and grabs his right arm channeling her Ki just as Master Kang has taught her to actually pull him off balance!

"Sweetie Belle, STOP!" Rarity cries but the two combatants are past hearing now, a challenge has been given, an attack made, and this fight will only end when one of them concedes or can no longer do battle!

The bad news for Sweetie Belle is that she is totally outclassed by her opponent: though Spike almost opens with his trump card of draconic fire he manages to hold off on that and instead unsheathes his claws, cutting Sweetie Belle's fighting-gee like nightgown with a slash of his fore arms and making her back up a step, but then she does a flip off the modeling stand and kicks him in the eye, to which he responds with an armored fist on an intercept course that cracks a rib, and sends her flying directly into a dressmakers dummy which buffers the impact by crumpling and snapping into three pieces while falling over! The wind knocked out of her by the impact Sweetie Belle APPEARS to be down and the fight over, until she rises, bruised but unbroken, and throws the metal base of the broken dummies' stand at the back of Spike's head! It impacts with a resounding *Clang!* and spike turns, slowly, eyes dancing with green flame and reason burnt away in the fire of draconic RAGE and launches himself at Sweetie Belle full ****! Only a quick telekinetic snatch by Rarity at the back of Sweetie Belle's nightgown keeps her from having her spine broken when Spike would have slammed her into the wall, and Spike instead smashes through the plaster and beams out into the night: but he is NOT done with this belligerent little filly, OH NO! Turning around he bounds on all fours back into the boutique, **** on his 'mind' and right now calling it that is being extremely generous, where from somewhere Sweetie Belle has gotten a freaking SWORD and tries to use it to cut his head off, but the blade only chips one of his spines and a glancing hit from his elbow leaves her with a split lip!
