To call the occurrence the young changeling drone saw an "Explosion of colors" would be quite the understatement. In a very similar fashion to the ever-so legendary "Sonic Rainboom" that the Element of Loyalty's bearer could pull off, the changeling saw a rather bright assortment of warm and cool colors explode out from the top of the hive in all directions, forming a veritable ring in the air. The drone's slightly glossed over opal eyes were filled with all sorts of wonder and amazement, the colors they saw streaking across their vision left their mouth agape. Then, for the first time ever, or for as long as anyone can remember, the drone smiled. The changeling sat there on their haunches, watching the seemingly phantom rainbow explode outward like a little filly watching their first ever fireworks display, totally engrossed in every little detail they were seeing; after all, this is the first time they've seen in color. As they sat there, their mind filling with all sorts of feelings and emotions for the first time ever, they failed to notice their eyes becoming a rainbow suddenly.
All at once, the changeling's body began to slightly glow a bright green color, the process of which made them feel tingly and warm. Letting out a soft meep, the drone shivered at the feeling of their carapace tingling and shifting a little, the glow growing brighter by the second. Despite all the strange tingles and feelings they were feeling at the moment, the changeling's smile only increased in size, the supposed rainbow growing brighter and more vivid in their eyes. The strange glow surrounding the changeling grew brighter and brighter, slowly enveloping their entire body in a white light, the drone's smile growing more adorable as they basked in the sudden array of colors. However, when the blinding white light started to blind them as well, their smile quickly changed into a frown of confusion, frantically looking down at themselves as the parts of their body encased in light began to seemingly harden and grow stiff.
"...W-Wha...? What is h-happening to me...?!" the changeling squeaked out quite loudly, perhaps in an attempt to call for help. Not a moment later however, they were quickly silenced as the open-air room was assaulted with a bright flash of colorful light. Once the semi-natural flashbang faded, where the changeling once stood (or sat, rather) now existed a brightly glowing cocoon of sorts similar to the ones the reformed changelings were wrapped up in before they changed. However, unlike the generically glowing white chrysalises of the average color bug, the cocoon the young drone found themselves entrapped in shined a rather pearlescent light, a multitude of colors shimmering across the woven threads. The unnaturally colored cocoon pulsed softly for a few moments, the fate of the changeling contained within unknown as everything was dead silent, not even the sounds of the throne room above crumbling could be heard. Then however, a rather soft whining noise was heard from within the confides of the woven changeling silk, akin to that of the hum one would hear with a tuning fork. The glowing colors slowly drained from the cocoon, being seemingly transmitted to the creature caught within as a very distinct changeling-shaped object became visible via luminescence.
Just as a certain dark chitinous monarch dived down the side of the hide, flying off into parts unknown as high speeds, the small changeling cocoon suddenly burst open in a blinding flash of light, a rather differently shaped changeling silhouette seen through the flash. Once the light died down, a rather colorful looking lump-of-a creature could be seen laying on the ground where the cocoon was. The "lump" let out a rather tired sounding groan, slowly shifting its position to roll onto its stomach and sit up, wobbling and almost falling over for a moment.
"Ugh...w-what...what happened...?" the changeling said through a groan, blinking a few times before clamping a hoof to their mouth in surprise. "w-w-wait, is this...my voice...?"
To the drone's surprise, the voice coming out of their mouth was not the somewhat soft, droning voice they were used to, but instead a rather cheerful feminine sounding one. They blinked once again, holding one of their front legs out in front of their eyes, their face slowly paling as they no longer saw a black, hole filled chitinous surface, but rather a smooth, somewhat fuzzy green colored one. The changeling meeped and quickly looked over the rest of themselves, seeing the smooth slightly-fuzzy exterior was commonplace on their body now, even their Elytra. They blinked a couple dozen times more, their eyes growing wider in shock upon seeing their old translucent blueish colored changeling wings no longer be there, instead replaced with a shimmering smooth green shell / elytra that held their actual wings. Just as they were about to open up their shell and inspect their wings, the sounds of some other changelings approaching made them meep and try their hardest to get up and go hide. The drone managed to wobble over into a conveniently placed nearby bush, flopping into it to hide from whoever was coming. Out of the darkness of the hive's tunnels came two more changelings, both surprisingly un-reformed: one dressed in the armor of a Hive Guard, the other, a dark gray colored eye patch over their left eye.
"Sounds like it came from ovah here," the one with the eye patch said in a rather strained voice "you don't think there's a little lass hidin' over here somewhere, do ya?"
"Nah, there's no way some mare would even think of coming close to the hive," the other one spoke, their tone of voice somewhat soft, yet equally loud at the same time "you should know this already, Rostrum." the armored changeling rolled their eyes, turning back around to walk into the hive once more.
"Well I don't know anymore, aight? It very well could be, what with all them clown-colored bugs up there buzzin 'bout." harrumphed 'Rostrum', shrugging their shoulders and following the other one back inside. "besides, its not like dumb old Nim would be able to protect the west wall anyway, what with her puttin' about blindly and all that~"
Both of the changelings laughed rather heartily as they vanished back into the hive, their almost bully-like personas soon gone from sight and hearing. Sensing that it was safe to come out now, the effeminate-voiced drone slowly walked out of the bushes, managing to keep "her" balance now. They sighed and flattened her ears against her head somewhat, seemingly depressed from what the two changelings from before were talking about. The reformed drone slowly walked away with their head down, scuffing their hooves as they headed down the small slope that lead to a lower part of the hive. As they continued down the path, the changeling passed by a rather large chunk of the hive wall that had broken off, unveiling a super reflective surface underneath. Blinking a few times, the changeling stopped and turned to look at the "mirror", slowly approaching it with caution, as if worried for what they were about to see in the reflection.
Upon seeing themselves in the makeshift mirror of sorts, their suspicions and worries were proven true somewhat: the young changeling drone had indeed reformed, their entire black chitinous form fully replaced with the smooth coat of a reformed-ling. The drone blinked a few times once more, staring at their face in particular in the "mirror"; their facial shape had changed to be softer and less threatening looking, and upon opening their mouth, confirmed that they no longer had fangs either. What made the changeling confused however was how their eyes looked: it was weird enough that they now had eyelashes befitting a mare, but now their eyes were a solid shade of pink, their "pupils" a barely noticeable lighter shade as well. Upon further inspection of their body in the reflection, and what little they remembered of the two changelings from before when compared to how they looked now, the drone saw their body was more lithe and smooth then before. Which, when combined with the rather embarrassing knowledge and feeling that "something else" was different about them, confirmed their possible suspicions that they both sounded and looked like a female now; which she shrugged off somewhat, the drone had always had a softer more girly personality anyway.
The thing that made her truly stop and stare at herself however was what her neck-fin and tail had become. Where a dime-a-dozen black neck-fine once was now harbored a full head of hair, naturally styled and arranged in a fashion similar to a buffalo chief's headdress; and her once blueish slightly-torn looking changeling tail was now replaced with a somewhat bushy and naturally "dread-locked" tail. What truly caught creature's eyes when they looked at her mane / tail however was how they were colored, a splash of color weaved into each and every strand that came from her head and rear, forming a veritable rainbow over her body (even if it was a few colors short of an actual rainbow). The changeling mare raised an eyebrow as she tilted her head from side to side, moving her rump a little to get a better look at herself.
"Huh...that's...probably not normal...?" she said as she gave her body one final look in the make-shift mirror, blinking and standing up straight as she remembered something. "Oh right, wings...gotta see if those still exist~"
The slightly gradient-tinted green Elytra on her back softly opened up, a pair of semi-transparent wings now peeking out gently. Then, as if excited by something, both of her wings shoot out of her back into flying position with a sort-of "pomf". The moment her wings hit full mast in the air, the changeling's vision was suddenly assaulted with a rainbow of colors and gradients, almost as if the bug had stumbled onto some hallucinogenic plants. The drone meeped and quickly closed her wings, tucking them back inside of their shell before lurching over onto the ground, clamping her eyes shut and pressing her hooves against them to try and block out the colors. A few moments later, she slowly opened her eyes and blinked rapidly, her vision normalizing finally. Letting out a sigh of relief, she plopped back onto her haunches and shook her head.
"Oh thank goodness..." she said, softly chuckling under her breath at her vision returning to normal.
" 'EY! THERE YOU ARE!"
The changeling was snapped out of her soft happy trance by a loud shout, quickly looking up to see the eye-patched drone pointing towards her. The other changeling's face slowly curled up into a devious smirk, lowering their hoof before starting to walk over to her.
"I knew there was a little ole' lass hanging about out here, I just needed to catch 'er in the act," they said, starting to speed up their approach towards the mare. "and oh boy did I catch 'er~"
The changeling mare slowly tilted her head to the side, staring at the other drone as they approached with wide eyes. She raised an eyebrow and tilted her head to the other side, giving her "pursuer" a confused and curious look
"Huh...so that's what I used to look like...neat" she said under her breath, giggling softly. she sat up straight once more as her cute giggling expression slowly faded, pointing to the changeling like they once did to her; or rather, to the air beside them.
"So uh...what's that next to you...?" the mare questioned out loud this time as she gestured to the other drone's side. The eye-patched changeling stopped their advance and blinked, looking over their shoulder to where the fem-ling was pointing.
"...I don't see nothin...you gotten into the 'shrooms or somethin, lass?" they questioned back, seeming rather confused. While the roughed-up changeling couldn't see anything, the mare certainly could, and she was very confused by what she saw.
Besides her vision slightly slipping back into the rather vivid color pallet from before, she also saw a cloudy-looking apparition beside the eye-patched changeling; or to be more specific:
A phantom looking skull
