Thorax, King Of The Changelings as most say and being the first one of the Hive was quite happy that Ocellus and many of his friends and fellow Buggos were enjoying the new Transformational Potions that were created from the Alicorn Princess Twilight Sparkle as the Student Changeling was enjoying being a rubbery living pool toy out on a beach while also hearing about Sandbar and Smolder becoming even a living Balloon and another Pool toy respectively. Despite his excitement and literal love for these potions he was still a bit shy on taking and trying one of them, in which his older Brother Pharynx would tease him about him being more passive than the General and Prince of the Hive. Thorax was quite a bit touched, understanding he was in a fact quite still a bit shy even from Ember's advice but it was mostly around taking the potions...and it was then he decided to go ahead with one that was a gift from Pinkie Pie from helping her babysit for a while a few days ago, how grateful!

The Potion in question was an Elasticity and Rubber Potion, its contents were a shiny, rubbery and tick liquid that smelt like rubber but at the same time smelt of sweet peaches and lemon, even when his species had no nose-holes he still had his nodes to sense the said love and care put into this potion and with no hesitation he drank a big portion of it, which was intended to have a side effect which would benefit even more to the Friendly Bug-horse.
TF Sequence start:

His semi-hard Chitin was beginning to bubble all over which in first scared him as he thought it felt like his skin was melting, but thus he calmed down as his chitin was feeling a lot more smoother and rubbery, the sun was giving him more shine than usual as the sequence was working quite fast in regards! And soon his entire body was fully converted into rubber! Well externally for the most part as his features like mouth and eyes began to feel a lot more flatter and painted on, but still functional as always as his antlers began to even wobble on their own due to the stimulus of control that was seeping into him...he felt he had more control of his body parts than ever before with he could shape his hoof into a rectangle, which surprised him!

It was now over yet of course as his insides were changed and melted into pure, living, breathing rubber...he was now a molded rubbery construct of himself...as he felt more nerve and control to malleate his body in anyways how! But before he could test some more he suddenly saw orange rings appear on his forelegs on both sides, which made him gasp but and blink a bit in confusion. On his legs and hip area, a Dark Magenta the same as his elytra colored raced up his thighs and stopped at the belt that had formed around his waist, stretching his neck down to see it also had a Crystal Heart emblem engraved into it...this made him smile to that day of meeting his new friends when he was still a Drone...but thus while retracting his neck back a Dark green that was the same as his Thoracic shell's color also engulfed the rest of his...well...thorax! Even covering up his elytra though he felt he wouldn't need them anytime soon...he could still feel the natural shapeshifting power of himself still resonate and now he was gonna have more options with his own body in a stretchy way...

And as the said costume of Dark Green and Magenta had fully formed and merged with his new rubbery form, becoming a literal part of his body as there was no edges to even pull on them like normal clothing, this didn't bother Thorax really, he could possibly feel the need to mold some new wings in place on his covered back after all! And finally, looking into a reflective mirror he could see an eyemask forming around his compound, magenta eyes, in the style of his orange antlers with spikes on the ends for a stylistic choice...and on his chest was a big orange "T" all all bendy and stretchy in the style of said appendages and even had transparent wings at the back of it!

TF Sequence End:

With all the changes now done to his body he now was all rubber and no organic material now...with full shapeshifting dialed up to eleven and now with a perma-costume of a superhero he just felt so happy, joyful and more confident too as he stood up on his hind legs, using his flexible form to adjust his back to a bipedal position to take a look at his proud looking form with a gleeful smile! Smirking as Pharynx and the others would be surprised he thus arched over to a clear area where nothing or anyone could get hit accidentally as he took a deep breath. And thus in a few seconds he was contorting his torso like a spring! Stretching it longer and longer and to accommodate his hind legs also began to elongate and stride over to further places, the knees and legs themselves noodling out comically like a real elastic superhero!

His front legs would stretch out in a less twisty fashion upon reaching the same as his hind legs, his hoofs began to wobble as he focused something that he read before in his interest in comics from the Ponies. His right hoof enlarged and reshaped into a large cylindrical mallet, whacking it at a cracked stone it was smashed to pieces with the shrapnel harmlessly bouncing off his rubbery body which made him smile more. His right hoof on the other hoof had split and lengthened individually until it was a giant claw of a spanner! With even an adjustable grip as he snapped it like a crab at some imaginary villains which made him chuckle playfully at that.

Stretching out his neck until it was long as a young giraffe, he focused all the elastically power into his antlers as the top of them began to inflate and flail around at first...and then with a big FWOOMPF, The top of his antlers, once sharp Stag-beetle horns were turned into rectangular plates! They looked like giant fly swatters as thus stretching them out to the front of his snout for him to see he clapped them together, this would be a good sorta power to squish villains while being creative with his new power. And that, still being stretched and proudly standing he declared a new name: Thorlastix! as his new secret-identity! Or an alternative one being Elastix for a less obvious one! He was ready to save his friends and hive anytime! Maulwurfs beware! Cause Elastix the Rubbery Changeling King is Here!

The End
